dading typhoon classification

1 - tropical cyclone winds of 30-60 kph are expected within the next 36 hours. Billie reached tropical storm intensity on September27 as it moved west. The first of the six members of the class to be commissioned was Dmitry Donskoy (TK 208) in 1981, followed by TK 202 in 1983, Simbirsk (TK 12) in 1984, TK 13 in . The new public storm warning signal system, signed last May 18, is as follows: PSWS No. Feature extraction result of some convolution kernels. [196], Clara weakened over Luzon but remained a typhoon upon emerging into the South China Sea, where it eventually reattained one-minute sustained winds of 150km/h (90mph). The 1964 Pacific typhoon season was the most active tropical cyclone season recorded globally, with a total of 40 tropical storms forming. [219][218][12]:78 Louise continued to intensify after passing the island, and attained its peak intensity on November18 with one-minute sustained winds of 305km/h (190mph) and a central air pressure of 915hPa (mbar; 27.09inHg). [117] During this period, an airplane investigating the storm identified multiple wind circulations at the center of Kathy and the storm's clouds were asymmetric. Natural disasters and land grabs:The politics of their intersection in the Philippines following super typhoon Haiyan. [12][230][231][232] A state of calamity was declared for Surigao del Norte,[233][234] prompting an intense relief effort amid an ongoing cholera epidemic and unrelated flooding. [11] Upon its detection, it was 1000km (620mi) southeast of Okinawa. [4] Total tropical cyclone counts for the 1964season include 40 from the CMA, 34 from the JMA, and 52 from the JTWC (including 7 considered "suspect cyclones"). Comput Biol Med. [32][33] Gusts reached 117km/h (72mph) and rainfall accumulations reached 94mm (3.7in) on the island, though there was "little damage. Its center passed between Alamagan and Guguan on May20 while maximum sustained winds in the typhoon were 140km/h (85mph). Naze lost power during the storm. [12]:75 An aircraft reconnaissance mission observed two concentric eyewalls spanning 11km (7mi) and 80km (50mi) across. [173][12]:77 The storm was last identified on September27. [198][201] At Tate's Cairn, a maximum wind gust of 220km/h (137mph) was measured. A tropical wave was spotted off South Vietnam on November 12. [198][12]:77 The storm then quickly weakened inland, transitioning into an extratropical cyclone on October15 and curving northeast back into the Pacific before it was last noted off Japan on October19. After traversing the Yellow Sea, Flossie made landfall on North Korea along the coast of the Korean Bay on July29 with winds estimated at 100km/h (65mph). Assertiveness Skills; Choices for Developing Emotional Intelligence Figure ( A ) shows the accuracy, Model accuracy rate at different neuron ratios. [12]:76, Lorna began west of the Mariana Islands on August10 and took a northeastward path throughout its duration. [77][12], Flossie's peak winds were approximately 75km/h (40mph) at the time of its closest passage to Okinawa, as measured by both aircraft reconnaissance and the USS President Roosevelt. A peak gust of 59km/h (39mph) was registered on the island, as well as 14mm (0.55in) of rain. [149][153][99] Over 10,000people were evacuated out of vulnerable areas in Hong Kong as the storm was feared to strike with a severity comparable to Typhoon Ruby a week prior. 2016 hydrometeology, typhoon warninig system. [20] A strong high pressure area south of Japan caused most storms during July to take slow and westward paths. Typhoons are some of the most serious natural disasters, and the key to disaster prevention and mitigation is typhoon level classification. Clipboard, Search History, and several other advanced features are temporarily unavailable. Modified wind signals [21], August was another above-average month for tropical activity in the basin. Set the target time : After Birth min max Before Death min max. LouiseMarge began as a cyclonic vortex associated with a tropical wave near Yap State on November12. [28], The first tropical cyclone of 1964 developed from a segment of the polar trough. [89] In the city of Kagoshima, 16homes were razed and 36others were damaged. Bethesda, MD 20894, Web Policies [6] The anomalous strength of tropical waves observed during the latter-half of the year may have contributed to season's high activity. Dtudes Dv. [136][23] Ship observations suggested that the system became a tropical depression August17 and became a tropical storm a day later. [73], The initial vortex that became Typhoon Flossie was detected east of Luzon on July24,[6]:121 embedded within an area of low pressure. 55th TC Session. Proudly created with Wix.com. Winds Hit Island In Philippines", Macau Meteorological Geophysical Services, Digital Typhoon - Typhoon Images and Information, https://en.wikipedia.org/w/index.php?title=1964_Pacific_typhoon_season&oldid=1134397479, Category 5-equivalent super typhoon(SSHWS), This page was last edited on 18 January 2023, at 13:43. [139][140] After reaching the South China Sea, Ruby turned towards the northwest and intensified further. [142] The strong winds and heavy rain caused widespread damage in Hong Kong, destroying thousands of homes and damaging thousands of others. [91] One death and 16injuries were reported in the two prefectures. [176] The typhoon caused 47fatalities and 530injuries in Japan. The combined effects of Iris and Joan killed as many as 7,000people and led to the worst floods in six decades. [22][138], The tropical disturbance that organized into Ruby arose from a tropical wave west of Saipan on August29. It then turned northeast and dissipated near the Taiwan Strait on August18. Typhoon is classificated by size. [6]:134 The disturbance became a tropical depression roughly (300mi) southeast of Guam on August2 and strengthened into a tropical storm later that day. [63] At the time, the typhoon was located approximately 320km (200mi) south of Shanghai. [69] However, the cyclone's winds continued to lessen before the system reached the islands. The nascent cyclone did not organize further, with aircraft reconnaissance unable to locate the storm's central vortex. [173] Based on data from the JMA, this was tied for lowest central pressure of any typhoon in 1964, along with Typhoon Sally. With the new typhoon classification, what will be the frequency of occurrence of different categories of typhoons? [12]:78[218] Meteorological agencies disagree on the evolution of Louise after landfall, with the JTWC and JMA determining that it dissipated on November21. These dates conventionally delimit the period of each year when most tropical cyclones form in the . [63] Reconnaissance aircraft observed an eye 75km (45mi) in diameter in Betty's first few hours as a typhoon. FOIA Accurate classification or prediction for typhoon intensity is crucial to disaster warning and mitigation management. [59] South Vietnam delivered 450metric tons (500short tons) of rice to victims of the storm in the Philippines. The probability is a measure of how likely it is that a certain event will occur. The primary objectives of data classification are: To consolidate the volume of data in such a way that similarities and differences can be quickly understood. Upon striking southern China, Ike was a large typhoon with gale-force winds extending out 315 km (195 mi) from the center. How to better use data of satellite cloud pictures to achieve accurate classification of typhoon levels has become one of classification the hot issues in current studies. Fran began its development northwest of the Marshall Islands around October13. [167]:76 It weakened quickly over land with the JTWC issuing its last advisory on the system on September15 and the CMA considering the system to have dissipated on September16. A tropical cyclone, also known as a typhoon, is one of the most destructive weather phenomena. [238] The storm then weakened to a tropical depression and strengthened no further, though data from tracking agencies disagree on Nora's demise, with the HKO and JTWC analyzing the storm to have dissipated in the direction of the South China Sea while the CMA and JMA indicating that the system continued northeast across the Philippines before dissipating over the Philippine Sea. [34] These winds diminished to 110km/h (70mph)just under typhoon intensityas Viola made landfall approximately 160km (100mi) west of Hong Kong at 03:00UTC on May28. [12]:78[251] Rice crops were damaged by heavy rainfall, and together with coconut crops, sustained losses estimated in the millions of U.S. The size of a typhoon is classified by the radius of the area in which the wind speed exceeds 15 m/s. [206][205] Fran continued north before curving east after October20, eventually transitioning into an extratropical system by October21 and dissipating on October23 over the open Pacific. [22] After taking a northward heading, Grace redeveloped on August3 and tracked across the Satsunan Islands. [167]:145 Ninety percent of homes were destroyed in Qung Bnh Province according to early reports. Military operations during the Vietnam War were suspended by the typhoons. Tropical cyclone is defined as a non-frontal, synoptic-scale cyclone developing over tropical and sub-tropical waters at any level and having a definitely organized circulation. The system curved towards the north and east before dissipating in the Sea of Okhotsk on August5. [1][2] All months between and including May and November were featured an above-average number of typhoons relative to the 19591976 period. Ferry services were suspended in the territory. Clara's winds topped out at 150km/h (90mph) as it made landfall on the coast of Aurora at Dilasac Bay on October5. At a certain point in their lifetime, four of them belonged to the super typhoon category (Wanda 1962; Ruby 1964; Rose 1971 and Hope 1979) while two belonged to the severe typhoon category ( Gloria 1957 and Ellen 1983).. [12] High waves and strong winds impacted southern Kyushu across the prefectures of Kagoshima and Miyazaki, unroofing homes and flooding nearly 200 homes. The following day, the a pressure of 1000mbar (hPa) was recorded in the center of the storm; however, this reading was not taken at the storm's highest intensity. The wave became Tropical Depression 45W on the 13th. [128][130] One landslide in Kagoshima killed 11people. Tropical cyclones are classified in accordance with the World Meteorological Organization's recommendation by their maximum sustained wind speeds near the centre. It initially tracked towards the southwest and attained tropical storm intensity in the central South China Sea on September25 according to data from the JTWC. With the introduction of Starfleet's command battlecruiser via the games official Delta Rising expansion . However, the system became more pronounced on October20 as it tracked towards the west-northwest, and became a tropical storm on October21 near the Philippines. By comparison, the U.S. Ohio-class submarines only displace about 19,000 tons. [118][119] The typhoon's winds peaked at 165km/h (105mph) on August14 before tapering as the storm curved towards the west-southwest. Typhoon timeline of 1964. [215] Joan attained typhoon intensity during the afternoon of November8 and reached its peak intensity with winds of 130km/h (80mph) shortly thereafter. [43][40] Further inland, the storm relieved drought conditions in the Chinese province of Guangdong. TYPHOON (TY) - a tropical cyclone with maximum wind speed of 118 to 220 kph. The Tropical Cyclone Warning System in Hong Kong will remain unchanged. The following day, the system quickly organized as it moved in a general eastward direction. [6]:168 The disturbance became a tropical depression and later a tropical storm the next day approximately 320km (200mi) northeast of Chuuk State. During the SALVEX, she was skippered by LCDR Peveril Blundell USN. [53] Thousands of trees were uprooted and basic utilities were brought down by the storm;[56] Manila was without power or water for at least 36hours. It then curved to the northeast, briefly entering the Sea of Japan and crossing the Noto Peninsula before traversing northern Honshu and emerging into the northern Pacific. Figure (. It will include their intensity, duration, name, areas affected, deaths, missing persons (in parentheses), and damage totals. [6]:86 This initial system moved towards the west-northwest, passing near Ulithi on June25. Classification. [12]:78[249] In total, 26people were killed and thousands of others were left homeless in the wake of Opal in the Philippines. Eventually in 1990 this 7th unfinished submarine was scrapped. The next day, the disturbance developed into a tropical depression and gradually took on a more westward course. [173] The JTWC recognized the storm as a tropical cyclone on September19 when it was located roughly 370km (230mi) northwest of Saipan, and assessed Wilda to have strengthened into a typhoon later that day. [12] According to the JTWC, Ida reached its peak intensity with maximum winds of 250km/h (155mph) and a central pressure of 925hPa (mbar; 27.31inHg). dollars. 21. [13] The typhoon then became stationary for nearly two days over the South China Sea with its winds concurrently falling to tropical storm intensity according to the JTWC. [227] Widespread destruction occurred in Surigao City, where the storm killed 312people and caused US$12.5million in damage. [12], In May1964, the western Pacific was characterized by anomalously high geopotential heights towards the northern part of the basin and low geopotential heights in the tropical regions. It then recurved creating a loop and finally exited to South China Sea. The JTWC was tasked with warning U.S. government agencies on tropical cyclones in the northwestern Pacific, in addition to researching and orchestrating aircraft reconnaissance into such storms. Its intensity oscillated as curved west and neared central Vietnam, peaking in strength with winds of 95km/h (60mph) on September26; these winds were inferred from maritime observations near the storm. [57] Abaca and coconut plantations in Luzon were seriously impacted. [115][22] Later that day, June attained a tropical storm and reached its peak intensity with winds of 75km/h (45mph). ii) Tropical Storm: Maximum wind speed at the center reaches 48 to 64 knots (25 m/s - 33 m/s) or, iii) Typhoon: Maximum wind speed at the center reaches 64 to 85 knots (33 m/s - 44 m/s) or scale, iv) Severe Typhoon: Maximum wind speed at the center exceeds 85 knots (44 m/s) or over scale. Firstly, the GridSat data set and the satellite of China Meteorological Administration were used to analyze the tropical cyclone scale data, and the typhoon data set was established. Model accuracy under different convolution, Model accuracy under different convolution kernels. Classification and intensity values will be based on estimations conducted by the JMA. [98] Between August67, Ida moved across northern Luzon with these winds. Zeqiang Wang. It's a simple strategy to use, and I'll walk you through it here in about one minute. [34], The Royal Observatory Hong Kong issued typhoon signal No. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low. The Joint Typhoon Warning Center (JTWC) estimates the, Storm durations and intensities are based on the International Best Track Archive for Climate Stewardship (IBTrACS), which is endorsed by the, Philippine Atmospheric, Geophysical and Astronomical Services Administration, United Nations Economic Commission for Asia and the Far East, Quarterly Journal of the Royal Meteorological Society, U.S. Agency for International Development, "Jelawat Strikes Mainland Japan After Slamming Okinawa", An Atlas of 1976 GEOS-3 Radar Altimeter Data for Tropical Cyclone Studies, "An Overview of the China Meteorological Administration Tropical Cyclone Database", "Review of ESACP/WMO Typhoon Committee Development in Past 50 Years", "A Statistical Study of Easterly Waves in the Western Pacific: JulyDecember 1964", 10.1175/1520-0469(1970)027<0195:ASSOEW>2.0.CO;2, Significant Achievements in Satellite Meteorology 1958-1964, "Climatological Data: National Summary (Annual 1964)", "The Philippines' Typhoon Alley:The Historic Bagyos of the Philippines and Their Impact", "The Weather and Circulation of May 1964", 10.1175/1520-0493(1964)092<0374:TWACOM>2.3.CO;2, "The Weather and Circulation of June 1964", 10.1175/1520-0493(1964)092<0428:TWACOJ>2.3.CO;2, "The Weather and Circulation of July 1964", 10.1175/1520-0493(1964)092<0477:TWACOJ>2.3.CO;2, "On the Relative Motion of Binary Tropical Cyclones", 10.1175/1520-0493(1983)111<0945:OTRMOB>2.0.CO;2, "The Weather and Circulation of September 1964", 10.1175/1520-0493(1964)092<0601:TWACOS>2.3.CO;2, "The Weather and Circulation of October 1964", 10.1175/1520-0493(1965)093<0059:AUDM>2.3.CO;2, Tropical Cyclones Affecting Guam (16711980), "Benefits from typhoons - the Hong Kong perspective", "Historical Storm Surges and Storm Surge Forecasting in Hong Kong", "PAGASA TROPICAL CYCLONES 1963-1988 [within the Philippine Area of Responsibility (PAR)]", "89 Dead Listed, 500,000 Homeless In Philippine Typhoon", "Typhoon Sweeps Manila, Causing 16 Deaths", "Official Week in Review: June 28 July 4, 1964", "The Church in the World: Report from the Philippines", Power of Partnership: 50+ Years of Aid in the Philippines, "Statistical Considerations of Pressure Oscillations Occurring near the Typhoon Center", "1964 Super Typhoon CORA (1964187N07150)", "A Pressure-Based Analysis of the Historical Western North Pacific Tropical Cyclone Intensity Record", "Typhoon Cora Weakens, Says Weather Bureau", "2 Navy Ships Collide In Wind Of Typhoon", "1964 Severe Tropical Storm GRACE (1964208N17142)", "Typhoon Grace Seen Southeast of Okinawa", "1964 Super Typhoon HELEN (1964209N17150)", "1 Dead, 16 Hurt As Typhoon Hits Southern Japan", 10.1175/1520-0493(1974)102<0476:HST>2.0.CO;2, "Typhoon-Associated Tornadoes in Japan and New Evidence of Suction Vortices in a Tornado near Tokyo", Tropical Cyclone Disasters in the Philippines, "Craft Missing During Typhoon With 31 Aboard", "Report Typhoon Ida Headed For Tonkin Gulf", "U.S. The rainfall brought an end to an over two-year-long drought that had prompted a year-long water rationing in the territory. [35][36][37]:72 More rain fell in roughly 24hours than in 1964 prior to Viola's arrival. The names were drawn sequentially from a set of four alphabetical naming lists and were all feminine. [120][6]:146, The storm's west-southwest path brought the center across the Ryukyu Islands and near Okinawa on August16 as Kathy began to execute a counterclockwise loop in its track. Its precursor disturbance developed from a trough of low pressure and became a tropical depression by August12; the next day, Lorna became a tropical storm, prompting JTWC warnings. [249][250] Opal caused significant property damage in Luzon and disrupted communications. 2022 May 31;8:e953. "[67] The Royal Observatory Hong Kong analyzed a substantially lower pressure of 920hPa (mbar; 27.17inHg) at the time of Cora's peak strength. [29][12]:74 On May19, a reconnaissance flight investigating Tess observed two eyes: the first and innermost eye measured 9.7km (6mi) across while the second was asymmetrical, with axes roughly 23km (14mi) and 14km (9mi) across. By using the Visual Geometric Group's model, Naval Base Subic Bay were evacuated into the South China Sea prior to the storm's arrival and people in low-lying fishing villages left for higher ground. [241] The Philippine Weather Bureau initially issued storm warnings for the eastern Visayas and Mindanao on December13 in anticipation of Opal;[242] these warnings were later extended to southern and central Luzon. [213], Similar to the formation of Tropical Storm Iris, Tropical Storm Joan originated from a tropical disturbance over the western South China Sea on November5. Can. [166][202][200] The official death toll from the storm in Hong Kong enumerated 26fatalities and 85injuries with 10unaccounted for,[13]:74 though press reports at the time indicated a higher death toll. [30][148] On September7, Sally reached its peak intensity over the Philippine Sea with winds of 315km/h (195mph) and a central pressure of 895hPa (mbar; 26.43inHg). [144]:1 Numerous ships sank or ran aground at the Hong Kong Harbor. [12]:78[252] These crop losses were most severe in central and southeast Luzon. "Nearly 15 hours after the typhoon struck, rain was still falling, but wind had subsided to 30 to 40 miles an hour," it . [107], In Hong Kong, the Royal Observatory advised ships to seek shelter in port and issued typhoon signal no. Dading Chong. [6]:50 The storm followed 1,130km (700mi) behind the larger Typhoon Winnie to its west and was eventually absorbed into Winnie's circulation over the Philippine Sea on June29. [183] At Uwajima, Ehime, a peak wind gust of 259km/h (161mph) was observed;[179] this was the strongest wind recorded in connection with the Wilda in Japan. Typhoon classification is introduced to facilitate the public in recognizing more intense typhoons, prompting people to be extra vigilant with the approach of more intense tropical cyclones. [70][71] By July10, Cora had weakened to a tropical depression. The storm weakened over the island but restrengthened over the South China Sea on approach to Hong Kong. The following day, Anita made landfall near Da Nang, Vietnam, and later weakened over land; the storm dissipated on September28. Set the target area : South North West East. Tracing a path similar to Tropical Storm Billie a week prior, the center of Clara passed south of Hainan on October7. [12]:77 Its proximity to the Crown colony led to the issuance of tropical cyclone signal no. [12]:77 U.S. Marine Corps helicopters were deployed to evacuate those affected by the storm in Tam K, Vietnam. Accurate classification or prediction for typhoon intensity is crucial to disaster warning and mitigation management. Gusts may be much higher than the mean wind speed and can exceed 220 km/h. [75][76] Elsie continued to weaken after emerging into the South China Sea and dissipated on July19. doi: 10.1080/02255189.2017.1308316. [133], The combination of converging low-level winds and divergence in the upper troposphere over the Philippine Sea led to the environmental conditions that resulted in the formation of Typhoon Marie. 1700 - 1800. [12]:76 On September4, Sally intensified into a typhoon and passed over Guam the next day with one-minute sustained winds of 155km/h (100mph). The initial disturbance formed on August12 and tracked towards the north and then curved east, becoming a tropical depression the next day. That is, we could have a strong but not large typhoon, and also a large but not strong typhoon. The intensity class had "weak" (which corresponds to Tropical Storm) and "middle" (which corresponds to Severe Tropical Storm), and the size class had "very small," "small," and "middle."These classes, however, might have given unreasonable relief to the people's attitude . A new type of the ships have been developed, as a reac. [125][126] Sustained winds topped out at 126km/h (78mph) with a peak gust of 195km/h (121mph) on Yakushima. [213], The deadliest storm of the 1964 season, Tropical Storm Joan brought heavy flooding that killed 7,000 people in Vietnam. The Typhoon class was developed under Project 941 as the Russian ''Akula'' class (), meaning shark. In this report, we propose a deep learning technique for high-accuracy estimation of the intensity class of a typhoon from a single satellite image, by incorporating meteorological domain knowledge. Eng. Pamela moved towards the west-northwest and subsequently weakened; on August26, the system weakened to a tropical depression and dissipated after a center of circulation could not be identified by aircraft reconnaissance. [29], Tess tracked towards the northeast after reaching typhoon intensity. [84], Tropical Storm Grace was the first of ten tropical cyclones in the 1964typhoon season discovered by meteorological satellites. [66], The initial system that led to Typhoon Doris began between Pohnpei and Chuuk State on July9. [132] The extratropical remnants of Kathy brought gale-force winds over the Bering Sea. Flooding broke through river embankments in 37locations and washed away 18bridges. The Typhoon-class is 566 feet long, 76 feet wide, and nearly 38 feet tall. HHS Vulnerability Disclosure, Help At around 06:00UTC on October21, Georgia made landfall on Luzon at Lamon Bay and passed north of Manila; one-minute sustained winds associated with the storm at the time were around 65km/h (40mph). [6]:96 The next day, the disturbance quickly developed into a tropical cyclone and strengthened into a typhoon by the end of July2. [80][12]:75 The USS Tawasa was dispatched to tow the stricken Weiss out to sea, but was itself grounded on an unforeseen pinnacle upon dislodging the Weiss. The number of typhoons was a new record, topping the 24 set in 1962. This initial disturbance traveled west-northwest, passing near Ulithi and Yap. [12]:77 An eye emerged on Nimbus satellite imagery on September20,[174]:159 and on September21, Wilda reached its peak intensity over the Philippine Sea with one-minute maximum sustained winds of 280km/h (175mph) as estimated by the JTWC and a minimum central pressure of 895hPa (mbar; 26.43inHg). However, this value was discordant with the 130km/h (80mph) winds occurring at flight level and a surface air pressure of 970hPa (mbar; 28.64inHg) estimated by the flights and by the JTWC. Light damage was wrought to facilities associated with U.S. Marine Corps support operations in Vietnam. [6]:81 Viola reached tropical storm strength on May25 and then curved northwest, strengthening further into a typhoon on May27 and peaking in strength with winds of 130km/h (80mph). [172][12]:77 The system quickly strengthened and reached tropical storm and later typhoon intensity on September14. The authors declare no conflict of interest. tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain. [113] Four people were killed after a mudslide pushed into a refugee camp and razed three houses Kwun Tong, with the 20,000m3 (700,000ft3) surge of mud placing areas under 7.5m (25ft) of debris. [231][235][236] In June1966, the Congress of the Philippines authorized 3.4million to be distributed annually through fiscal year 1969-70 for the province and its municipalities. The size of a typhoon is classified by the radius of the area in which the wind speed exceeds 15 m/s. The Session will also cover the new Strategic Plan 2022-2026 and development issues. [12]:78[219] On December12, Opal reached its peak intensity with one-minute sustained winds of 315km/h (195mph) and a central pressure of 895hPa (26.43inHg). PSWS No. Stud. 2020 Dec;50(12):4946-4957. doi: 10.1109/TCYB.2019.2920268. [87], Winds near the center of Helen were approximately 185km/h (115mph) as it crossed the northern Ryukyu Islands and Kyushu. [61], On June26, a disturbance formed from an easterly tropical wave southeast of Guam and strengthened into a tropical depression later that day. It had no official bounds; it ran year-round in 1964, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. Figures (, Feature extraction effect of different number of convolution kernels (Note: Q1 (1 1 convolution kernel), Q2 (3 3 convolution kernel), Q3 (5 5 convolution kernel), Q4 (7 7 convolution kernel), Q5 (8 8 convolution kernel), and Q6 (9 9 convolution kernel)). Two days later, Cora attained sustained winds of 260km/h (160mph) as it approached the central Philippines on a westward heading, according to the JTWC;[12]:75 this classified Cora as a super typhoon. In November 1991, Tropical Storm Thelma became one of the most devastating tropical systems to impact the Philippines in the 20th century. Winnie reached tropical storm strength on June27 and then typhoon strength on June28 as it rapidly intensified en route to southern Luzon. [73][6]:115 The depression intensified into a tropical storm two days later, with its course concurrently curving west. It maintained this intensity and remained quasi-stationary over the gulf. Dot then curved towards the west and made landfall on northern Luzon the following day with one-minute sustained winds of 130km/h (80mph).
