Typhoon Pat,known in the Philippines as Typhoon Luming,was a powerful typhoon that struck Japan during the summer of 1985. Pat is also one of three storms in the Western Pacific which interacted with each other. Originating from a monsoon trough towards the end of August,Pat first formed on August 24 several hundred miles east of the Philippines. It gradually intensified,and two days later,Pat was upgraded into a tropical storm. The cyclone initially moved east-northeast while continuing to deepen. However,Pat leveled off in intensity on August 27. After turning northwest,Pat attained typhoon intensity on August 28. Pat accelerated towards the north,and reached its peak intensity of 80 mph (130 km/h) on August 30. The next day,the storm crossed the southern Japanese islands and entered the Sea of Japan. Gradually weakening,Pat transitioned into an extratropical cyclone later on August 31. Early the next day,the storm moved ashore along northeastern Japan. The system dissipated on September 2 after reentering the Pacific Ocean. A total of 23 perished due to Typhoon Pat and 12 others were rendered as missing. Additionally,79 people were injured. Furthermore,38 houses in Japan were demolished,110 were damaged,and over 2,000 were flooded. More than 160,000 homes lost power. A total of 165 flights were cancelled.
Typhoon Pat originated from an active monsoon trough located east of the Philippines in the last two weeks of August. Forming around the time as Typhoon Odessa and Tropical Storm Ruby, an area of enhanced convection was first noted towards the end of August. At 0600 UTC on August 24, the Japan Meteorological Agency (JMA) started watching the system. Fifteen hours later, the Joint Typhoon Warning Center (JTWC) followed suit. At this time, the system was located within a favorable environment. The JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the afternoon of August 25. [1] Early the next day, the JMA upgraded the disturbance into Tropical Storm Pat. [2] [nb 1] Later on August 26, a Hurricane Hunter aircraft reported winds of 70 km/h (45 mph) and a pressure of 999 mbar (29.5 inHg), but did not locate a surface circulation. That afternoon, the TCFA was re-issued. Following additional Hurricane Hunter reports, which noted evidence of a surface circulation, the JTWC declared the system Tropical Storm Pat. [1]
Initially poorly organized, Pat headed east-northeast, south of a subtropical ridge. [1] At 0600 UTC on August 27, the JMA increased the intensity of the storm to 95 km/h (60 mph). [2] Meanwhile, the JTWC anticipated the storm to move east-northeast and separate from the monsoon trough before turning west-northwest under a weakening ridge. Instead, Pat drifted northeast, but remained situated within the monsoon trough. As such, the JTWC revised their forecast, and now expected the storm to move northwest due to the presence of an eastward moving trough situated over Mongolia. [1] Meanwhile, the JMA increased the intensity of Pat to 105 km/h (65 mph) early on August 28. [2] Several hours later, both the JTWC and the JMA upgraded Pat to a typhoon. [4] [nb 2] According to the JMA, the storm leveled off intensity for about a day. [2] By midday on August 29, some tropical cyclone forecast models began to show Pat emerging into the Sea of Japan west of the ridge. However, this theory was not supported by the JTWC as they believed that the ridge was too narrow to be picked up a trough. [1] That same day, the JTWC increased the intensity to 160 km/h (99 mph), equivalent to a Category 2 cyclone on the United States-based Saffir-Simpson Hurricane Wind Scale. [4] The next day, the agency finally revised its forecast and predicted the storm to enter the sea. [1] Around this time, the JTWC estimated that Pat attained peak intensity, with winds of 170 km/h (105 mph). During the evening of August 30, the JMA reported that Pat reached its peak intensity of 135 km/h (85 mph) and a pressure of 955 mbar (28.2 inHg). [4] By this time, the ridge was gone, though a trough was now located near South Korea. [1]
Shortly after its peak, Pat moved ashore along the southern tip Kyushu on August 31. [6] Overland, Pat began to weaken, and early the next day, the JMA downgraded Pat to a severe tropical storm. [4] Meanwhile, Pat began to interact with Odessa, as the systems were approximately 500 km (310 mi) apart. As Odessa moved east-northeast, Pat accelerated towards the north, and then emerged into the Sea of Japan later on August 31. [1] That evening, the JTWC downgraded Pat into a tropical storm. [4] At 2100 UTC that day, the JTWC noted that Pat had transitioned into an extratropical cyclone. By this time, all the convection activity was restricted to the northeast quadrant of the system. Early on September 1, Pat made landfall in Hokkaido along northeastern Japan. [1] At that time, the JMA estimated winds of 110 km/h (70 mph). [2] At midday, the JTWC stopped watching the system, [1] although the JMA continued to do so until 1800 UTC on September 2. [2]
While crossing Japan, [1] a peak rainfall total of 374 mm (14.7 in) was recorded in Ebino, including 271 mm (10.7 in) in a day. A peak hourly storm total of 107 mm (4.2 in) was measured at Gokaharadake on Nagasaki. Pat was responsible for strong winds, including a 69 km/h (43 mph) wind speed in Yakushima. [7] The island of Kyushu sustained the worst affects from the typhoon. [8] Twenty-three people were killed by the typhoon [9] while 12 others were listed as missing. [8] A 61-year-old man who died when knocked over by a street sign in Izumi. [10] A 35-year-old woman was crushed to death in Kagoshima when her home was demolished. [11] A total of 179 people were injured due to Pat, [12] including 23 on Honshu and 156 on Kyushu. [13] In Aomori, a tent fell on 400 people attending a sporting event, injuring 18. In the nearby Yamagata prefecture, a signboard at a school ground fell due to strong winds, injuring four students. [12] Nearby, in the Kumamoto prefecture, one man was struck and killed by a flying tin plate, another was swept out to sea, and a man died when a ladder fell on him. [11] Elsewhere, twelve fisherman perished at sea, [9] [12] seven of whom were not confirmed dead until September 2. [9]
A total of 38 houses in Japan were destroyed, [14] 110 were damaged, [8] and more than 2,000 were flooded. [14] Landslides were observed at 56 locations. Power was lost to 160,000 families. [15] A total of 165 flights were cancelled, delaying 15,000 passengers. [16] A total of 160 trains were cancelled. [17] Two bullet train lines experienced delays in Kyushu; [18] ferry and air service were also delayed there. [19] Offshore, ten fishing boats sunk, [11] including one Japanese cargo ship. [12] An additional 12 ships were rendered as missing. Ninety-five other boats took refuge in North Korea, [20] though 59 left on September 2 to return to Japan. [9]
The 2004 Pacific typhoon season was an extremely active season that featured the second-highest ACE ever recorded in a single season, second only to 1997, which featured 29 named storms, nineteen typhoons, and six super typhoons. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2004, though most tropical cyclones typically develop between May and October. The season's first named storm and also the first typhoon, Sudal, developed on April 4, later was reached typhoon status two days later, and became the first super typhoon of the year three days later. The season's last named storm, Noru, dissipated on December 21.
The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.
The 2002 Pacific typhoon season was a slightly above average Pacific typhoon season, producing twenty-six named storms, fifteen becoming typhoons, and eight super typhoons. It had an ACE over 400 units, making it one of the most active seasons worldwide. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2002, though most tropical cyclones typically develop between May and October. The season's first named storm, Tapah, developed on January 11, while the season's last named storm, Pongsona, dissipated on December 11. The season's first typhoon, Mitag, reached typhoon status on March 1, and became the first super typhoon of the year four days later.
The 1999 Pacific typhoon season was the last Pacific typhoon season to use English names as storm names. It also featured the lowest number of typhoons on record, with only five reaching this intensity. This was mainly due to a strong La Niña which persisted from last year. The season was also below-average in named storms, with only 20 of such spawning. It had no official bounds; it ran year-round in 1999, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The first named storm, Hilda, developed on January 6, while the last named storm, Gloria, dissipated on November 16.
The 1988 Pacific typhoon season was a very active season in terms of named storms, though it only featured 11 typhoons and 1 super typhoon. It had no official bounds; it ran year-round in 1988, but most tropical cyclones formed between May and November. Tropical storms that formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
The 1987 Pacific typhoon season was a below average season, though it featured a relatively high amount of typhoons. It had no official bounds; it ran year-round in 1987, but most tropical cyclones formed between May and November. Tropical storms that formed in the entire basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
Severe Tropical Storm Wukong was a slow-moving tropical cyclone which produced torrential rains over Japan. The tenth named storm of the 2006 Pacific typhoon season, Wukong developed out of a tropical depression over the open waters of the western Pacific Ocean. On August 13, both the Japan Meteorological Agency (JMA) and the Joint Typhoon Warning Center (JTWC) classified the depression as a tropical storm. The storm traveled along a curving path south of Japan, absorbing the remnants of Tropical Storm Sonamu on August 15 before turning towards the west. Wukong made landfall at peak intensity late on August 17 near Miyazaki City in southern Kyūshū. The cyclone remained over land for about 24 hours before moving out over the Sea of Japan. The storm weakened to a tropical depression before dissipating on August 21. Due to the slow movement of the storm, it produced heavy rains, peaking at 516 mm (20.3 in). Two people were killed due to rough seas produced by the storm and three others were injured.
Typhoon Angela, known in the Philippines as Typhoon Rubing, was an intense tropical cyclone that formed in late September 1989. The storm developed from a tropical disturbance in the monsoon trough and moved generally westward throughout its duration. The storm ultimately peaked in intensity as a super typhoon and struck northern Luzon in the Philippines. After weakening and traversing the South China Sea, Angela bypassed Hainan to the south and struck Vietnam before dissipating. The storm caused severe damage and 119 fatalities in the Philippines. Thousands of houses were damaged, and hundreds of thousands of residents were impacted by the typhoon. Monetary damage is placed at $8 million.
Typhoon Oliwa was one of a record eleven super typhoons in the 1997 Pacific typhoon season. Oliwa formed in the central Pacific Ocean on September 2 to the southwest of Hawaii, but it became a typhoon in the western Pacific. Oliwa explosively intensified on September 8, increasing its winds from 85 mph to 160 mph in a 24‑hour period. Afterward, it slowly weakened, and after passing east of Okinawa, Oliwa turned northeast and struck Japan with winds of 85 mph (137 km/h). There, it affected 30,000 people and killed 12; thousands of houses were flooded, and some were destroyed. Offshore South Korea, the winds and waves wrecked 28 boats, while one boat went missing with a crew of 10 people. Oliwa dissipated on September 19 in northern Pacific Ocean near the International Date Line.
Typhoon Alex, known in the Philippines as Typhoon Etang, affected the Taiwan, China, and South Korea during July 1987. Typhoon Alex developed from the monsoon trough that spawned a tropical disturbance late on July 21 southwest of Guam which organized into a tropical depression shortly thereafter. The system steadily became better organized, and the next day, a tropical depression had developed. Satellite intensity estimates gradually increased, and on July 23, the depression intensified into Tropical Storm Alex. After initially tracking west-northwest, Tropical Storm Alex started tracking northwest. An eye developed on July 24, and on the next day, Alex was classified as a typhoon, when Alex attained its peak intensity of 120 km/h (75 mph) and a minimum barometric pressure of 970 mbar (29 inHg). Alex weakened while tracking more northward, though interaction with Taiwan resulted in a more westward track starting on July 27. The storm struck near Shanghai as a tropical storm, and weakened over land, although it remained identifiable through August 2.
Typhoon Fengshen was the strongest storm of the 2002 Pacific typhoon season. It developed on July 13 from the monsoon trough near the Marshall Islands, and quickly intensified due to its small size. By July 15, Fengshen attained typhoon status, and after initially moving to the north, it turned toward the northwest. On July 18, the typhoon reached its peak intensity of 185 km/h, according to the Japan Meteorological Agency. The Joint Typhoon Warning Center estimated peak winds of 270 km/h, and the agency estimated that Fengshen was a super typhoon for five days. This broke the record for longest duration at that intensity, previously set by Typhoon Joan in 1997, and which was later tied by Typhoon Ioke in 2006.
Typhoon Ken, known in the Philippines as Typhoon Tering, was the fourth typhoon to strike Japan during the 1982 Pacific typhoon season. Forming along the western end of the monsoon trough in the Philippine Sea, the system had organized into a tropical depression on September 16, and by that night a tropical storm. As a compact system, rapid intensification continued, with Ken becoming a typhoon on the evening of September 17 and a major typhoon on September 18. The cyclone up to this point had a history of progressing slowly west-northwest, but Ken eventually stalled on September 20 and became a larger cyclone. As a mid-latitude trough to its north deepened, Ken took off to the northeast towards Okinawa. Ken made landfall upon Shikoku early on September 25, and moved onward into the Sea of Japan where it evolved into an extratropical cyclone. Five people were killed while 18 others were hurt. A total of 114 mudslides were reported, resulted in over 2,000 homes flooded. Additionally, 12 homes were damaged or destroyed. Seventy-four flights were cancelled as well.
Typhoon Thad, known in the Philippines as Typhoon Openg, was considered the worst storm to affect Japan in two years. Originating from a monsoon trough, Typhoon Thad was first classified on August 15, 1981 and was upgraded into a tropical storm the next day. Meanwhile, Thad moved north and northeast and attained typhoon intensity midday on August 18. The next day, the storm reached its peak intensity of 80 mph (130 km/h). On August 22, Thad accelerated northward, striking eastern Japan the next day just before weakening to a tropical storm. After passing through the country, the cyclone transitioned into an extratropical cyclone on August 23.
Typhoon Faye also known in the Philippines as Typhoon Norming was a long-lived typhoon that struck the Philippines in August 1982. On August 16, a weak tropical disturbance was moving towards the southern Philippines. Initially, land interaction with the Philippines with prevented significant development. After crossing the Philippines, the disturbance emerged into the South China Sea and increased in organization. It was upgraded into a tropical storm by midday on August 22. Thereafter, Faye began to steadily strengthen, and attained typhoon intensity later that day. On August 23, Typhoon Faye reached its peak intensity, which the storm would maintain for approximately 12 hours. A small cyclone, Faye moved northward on August 24 due to the weakening of a ridge over China. Thereafter, its center was disrupted by land interaction with the Philippines. As such, the storm weakened slightly before striking Luzon on the morning of August 25. Severe flooding and strong winds were recorded. More than 5,000 houses were damaged while 220,000 were homeless. Furthermore, around 7,000 people sought shelter. There were 18 injuries and 41 deaths in the Philippines. Overall, damage amounted to $9.6 million (1982 USD). Across Japan, two people perished.
Typhoon Hal, known in the Philippines as Typhoon Kuring, was the strongest cyclone to affect southern China since 1983. Hal originated from a monsoon trough that formed in early June 1985. The system gradually became better organized, and on June 20, the storm attained tropical storm. Intensification continued and the storm reached typhoon intensity later that day. On the evening of June 21, Hal reached peak intensity, before passing south of Taiwan. The storm weakened slightly on June 22, and lost typhoon intensity two days later. Later on June 24, Hal moved onshore northeast of Hong Kong. Hal dissipated three days later.
Typhoon Kim, known in the Philippines as Typhoon Osang, was the second typhoon in a week to directly affect the Philippines during July 1980. Like Typhoon Joe, Kim formed from the near equatorial monsoon trough in the northwestern Pacific Ocean on July 19. The disturbance tracked quickly westward-northwest underneath a subtropical ridge, reaching tropical storm strength on the July 21 and typhoon strength on July 23. After developing an eye, Kim began to rapidly intensify, and during the afternoon of July 24, peaked in intensity as a super typhoon. Several hours later, Kim made landfall over the Philippines, but the storm had weakened considerably by this time. Throughout the Philippines, 40 people were killed, 2 via drownings, and 19,000 others were directly affected. A total of 12,000 homes were destroyed and 5,000 villages were flooded. Less than a week earlier, the same areas were affected by Joe; however, Kim was considered the more damaging of the two typhoons. Land interaction took its toll on Kim, and upon entering the South China Sea, the storm was down below typhoon intensity. Kim continued northwestward but its disrupted circulation prevented re-intensification, and it remained a tropical storm until hitting southern China July 27 to the northeast of Hong Kong, where only slight damage was reported. Later that day, Kim dissipated.
Typhoon Songda, known in the Philippines as Typhoon Nina, was the fifth-costliest typhoon on record. The 18th named storm of the 2004 Pacific typhoon season, Songda developed on August 26 near the Marshall Islands. Following a path that Typhoon Chaba took nine days prior, Songda moved west-northwestward and strengthened quickly amid favorable conditions.
Typhoon Dinah, known as Typhoon Luding in the Philippines, was the costliest tropical cyclone to form in the 1987 Pacific typhoon season. It also was the fourth typhoon to form during August 1987. An area of low pressure developed near Guam on August 19, and two days later, the low reached tropical storm intensity as it moved generally west. Intensification was initially gradual, with Dinah becoming a typhoon early on August 24, before it subsequently intensified at a faster pace. Dinah reached its highest strength on August 26 before turning northward on August 28 and into a less favorable conditions aloft, which prompted weakening. Dinah entered the Sea of Japan after passing near Okinawa on August 29, where Dinah leveled off in intensity. The system then began to recurve towards southwestern Japan, and after tracking through the area, Dinah transitioned into an extratropical cyclone on August 31, although the remnants could be traced for four more days as it approached the International Date Line.
Severe Tropical Storm Irving, known in the Philippines as Tropical Depression Edeng, was an early-season tropical cyclone that struck southern Japan during August 1992. A distinct but weak low-pressure area developed within the Western Pacific monsoon trough. A tropical depression formed on July 31, and following an increase in both organization and thunderstorm activity, the depression attained tropical storm intensity on the morning of August 2. After tracking west-northwest and then north, Irving turned to the northeast, and attained peak intensity a day later. In response to a subtropical ridge to the north, the system began to track west-northwestward, and made landfall at maximum intensity over southwestern Shikoku at peak intensity. Irving turned sharply to the west and rapidly weakened, dissipating over the Korea Strait at noon on August 5.
Typhoon Holly, known in the Philippines as Typhoon Isang, affected South Korea, Japan, and the Soviet Union during August 1984. Holly originated from the monsoon trough that extended eastward from its original position in mid-August 1984. Over a period of several days, the system slowly became better organized as it tracked westward, although the system did not initially develop a well-defined center. On August 15, a tropical depression was declared, and on the next day, the depression was upgraded into Tropical Storm Holly. Holly slowly gained strength, becoming a typhoon on August 17 as it passed near Okinawa. The typhoon turned northwest and then north as it rounded a subtropical ridge. At noon on August 19, Holly attained its peak intensity of 130 km/h (80 mph). Shortly after its peak, Holly accelerated northeast due to the westerlies in the general direction of the Korean Peninsula. Land interaction with South Korea triggered a weakening trend, and after entering the Sea of Japan, Holly began to transition into an extratropical cyclone. Thunderstorm activity quickly decreased near the center, and by August 21, Holly had completed its extratropical transition.
