From Wikipedia, the free encyclopedia
The 1996 Pacific typhoon season was an above average season, producing 30 tropical storms, 16 typhoons and six super typhoons. It has no official bounds; it ran year-round in 1996, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.[1] These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. However the first named storm, Ann, did not develop until April 3. The final named storm, Greg, dissipated on December 27.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1996 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. 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.
On February 23, a large area of convection developed south of the Philippine Sea. The convection developed into a low pressure area and was at first bombarded by wind shear, but conditions soon turned favorable which allowed it to strengthen rapidly on February 27 before becoming a Tropical depression later that day. The JMA upgraded 01W into a Tropical Storm before it drifted over the Philippines on February 29, and weakened slightly due to land interaction.[2][3] On March 1, a cold front brought cold, dry air and vertical wind shear which pushed the system south caused the system's low level circulation center to become exposed. The exposed remnants of 01W continued to drift south, before being completely absorbed by the Intertropical Convergence Zone.[citation needed]
Tropical Storm Ann (Biring) was a destructive tropical storm that hit the Philippines in 1996. Making landfall on April 7th, it caused widespread flooding and landslides, leading to over 1,000 fatalities. The storm's impact was severe, resulting in significant property damage estimated at $40 million. Ann was the second tropical cyclone to affect the Philippines that year, highlighting the region's vulnerability to such weather events.
Tropical Depression 03W was a short-lived tropical cyclone that formed in the South China Sea during April 1996. It existed for only a brief period, from April 25th to 26th. While its lifespan was short, it was a part of an active typhoon season in the region. Despite its limited duration, it contributed to the overall weather patterns and maritime conditions in the area during that time.
Typhoon Bart, also known as Konsing, was a tropical cyclone that formed in the Western Pacific Ocean in 1996. It developed on May 8 and intensified into a typhoon on May 12. While it didn't make landfall, it was a significant storm that tracked northwestward across the open ocean. Bart eventually weakened into an extratropical cyclone on May 18.
Cam developed over the South China Sea on May 18. The cyclone headed northeastward to east-northeastward and dissipated over the Pacific Ocean on May 23.
Dan existed from July 5 to July 11.
A Tropical Upper Tropospheric Trough spawned Tropical Depression 7W on July 10 over the open Western Pacific. It tracked generally west-northwestward, strengthening to a tropical storm on the 14th. On the 15th Eve became a typhoon, which was followed by a period of explosive deepening to a 100 mph Typhoon, with a pressure drop of 40 mb from early on the 15th to early on the 16th. An eyewall replacement cycle weakened Eve to a 95 mph typhoon, but as the outer eyewall contracted, the storm again reached wind speeds of 97 mph before hitting southern Japan on the 18th. Rapidly weakening over the mountains, Eve turned eastward over the islands and the last warning was issued on the 20th. It restrengthened to a tropical storm east of Japan, and continued northeastward until dissipation on the 27th. Eve, despite being a Category 4 at landfall, caused no reported deaths and only 9 injuries.[4] However, it destroyed 2,361 homes and damaged another 933 homes. Total damage in Japan is estimated at ¥78.8 billion (USD$513 million).[5]
An active monsoon trough over the Western Pacific Ocean developed 3 typhoons; Frankie, Gloria, and Herb. The first, Frankie, developed in the South China Sea on July 19. It tracked west-northwestward and became a tropical storm on the 21st. After crossing the island of Hainan Frankie rapidly intensified to a 100 mph typhoon, 945 millibar over the Gulf of Tonkin. It made landfall over northern Vietnam on the 23rd, and dissipated 2 days later over China. 104 people were reported killed or missing in association with Frankie,[4] and damage figures in Vietnam are estimated at over 16.65 trillion (US$1.4 billion) (1996 US Dollars).[6]
The same monsoon trough that spawned Frankie also spawned a tropical depression on July 19 east of the Philippines. It headed northwestward, slowly organizing into a tropical storm on the 22nd. The next day Gloria reached typhoon strength, and a day later it reached its peak of 100 mph winds. Gloria brushed the northern coast of the Philippines and turned northward to hit Taiwan on the 26th. After crossing the island and the Taiwan Strait, Gloria hit China where she dissipated on the 27th. Gloria caused 23 casualties, 20 of which were in the northern Philippines. In addition, damage was estimated at $20 million (1996 USD).[4]
Super Typhoon Herb was the strongest and the largest storm of 1996. Herb struck Ryūkyū Islands, Taiwan and China. Maximum sustained winds of the cyclone reached 160 miles per hour (260 km/h) over the open ocean. The system led to 590 casualties and US$5 billion in damage (1996 dollars).[4]
Ian existed from July 27 to July 31.
Joy existed from July 29 to August 6.
A monsoon depression developed on July 28 over the open Pacific Ocean. It headed northwestward, slowly consolidating to become a tropical storm on the 5th. While south of Japan, Kirk drifted to the southeast and looped back to the west, strengthening to a typhoon on the 8th while looping. It continued slowly northwestward, and while curving to the northeast Kirk reached a peak of 110 mph winds. The typhoon struck southwestern Japan at that intensity on the 14th. It weakened over the country, and dissipated on the 16th over the northern Pacific. Kirk caused heavy flooding, resulting in at least 2 deaths and ¥20.6 billion (USD$134 million) in damage.[4][5]
Lisa developed over the South China Sea on August 4. The storm headed northeastward and struck China on August 6, then dissipated two days later.
Tropical Depression 15W existed from August 11 to August 17.
The monsoon trough spawned a tropical depression over southern China on August 11. It drifted southwestward, entering the Gulf of Tonkin on the 12th. An extremely small cyclone, it reached tropical storm strength on the 13th and a peak of 60 mph on the 14th. Marty made landfall on the 14th on northern Vietnam, where it dissipated 3 days later. Though small and somewhat weak, Marty managed to cause severe damage and flooding, amounting to the deaths of 125 with 107 people missing.[4]

On September 2, a tropical depression developed well east of the Philippines. It headed west-northwestward, reaching tropical storm strength on the 5th and typhoon strength on the 6th. On the 7th Sally rapidly intensified to a 160 mph Super Typhoon while passing just north of the Philippines. It weakened slightly yet steadily to a 115 mph typhoon over the South China Sea, hitting the Luichow Peninsula of China on the 9th, and dissipated the next day over the country. Sally brought heavy rain and damage to China, causing 114 casualties, 110 people missing, and economic losses estimated at $1.5 billion (1996 USD).[4]

Tom existed from September 11 to September 21.
An active monsoon trough that also developed Typhoons Tom (25W) and Violet (26W) spawned a tropical depression in the Gulf of Tonkin on September 16. It moved counter-clockwise around Hainan Island, becoming a tropical storm on the 17th and a typhoon on the 19th. It crossed the narrow Hainan Strait between Hainan and China, and continued west-southwestward across the Gulf of Tonkin. Willie made landfall on Vietnam on the 22nd, and dissipated the next day. The typhoon resulted in 38 fatalities from flooding.[4] Damage in Vietnam reached over 500 billion dong (US$40 million, 1996 dollars).[6]

Tropical Depression 31W existed from October 13 to October 17.
Beth developed on October 13. It struck Luzon on October 17 and then reached the South China Sea. On October 21, Beth moved ashore in Vietnam and dissipated the next day. One person had drowned in northern Philippines, in the province of Ifugao, while another four remained missing in another province. The PAGASA recorded sustained winds of 120 km/h (75 mph) as the storm impacted the northeastern portion of Cagayan.[8][full citation needed]

Tropical Depression 34W formed over the Sulu Sea on October 24. It struck Palawan on the next day. After tracking across the South China Sea, 34W made landfall in Thailand on October 30. It crossed the Malay Peninsula and entered the North Indian Ocean basin later that day. The storm dissipated shortly thereafter, but later re-developing into the Andhra Pradesh cyclone.
35W killed 60 people and caused $138 million in damages.[9]
A cluster of thunderstorm activity formed southeast of Guam on November 2. The system slowly organized, becoming a tropical depression on November 4. Remaining nearly stationary, the depression intensified into a tropical storm late in the day. The cyclone then turned westward, becoming a typhoon by November 7. Late in the day, Dale passed south of Guam bringing winds as high as 74 knots (137 km/h) and high seas which overtopped cliffs 30 metres (98 ft) high. Damage on the island totaled US$3.5 million (1996 dollars.) Continuing to intensify, Dale became a supertyphoon in the Philippine Sea on November 9. On November 10, Dale turned north, recurving east of the Philippines. On November 14, Dale accelerated east-northeast at more than 60 knots (110 km/h) as it became an extratropical cyclone.[4]
In the Philippines, Ernie killed 24 people, left 12 others missing and caused $5.1 million in damages.
Tropical Storm 38W existed from November 4 to November 12.
Tropical Depression 39W developed on November 6. It struck Luzon on November 8 and then dissipated two days later.
Tropical Depression 40W developed on November 25. It struck Mindanao several hours before dissipating on November 30.
Tropical Depression 41W existed over the South China Sea from December 14 to December 20.
A tropical depression formed on December 21, when a low-level circulation center began to produce deep convection. The depression strengthened into a tropical storm the next day, and was given the name Fern by the Joint Typhoon Warning Center (JTWC). The storm slowly intensified into a Category 1 typhoon on the Saffir–Simpson hurricane wind scale, according to JTWC. Fern peaked north of Yap on December 26, with JTWC assessing winds of 150 km/h (90 mph), while the Regional Specialized Meteorological Center, Japan Meteorological Agency (JMA) assessed peak winds of 110 km/h (70 mph), just below typhoon strength. The storm soon became sheared and weakened slowly. Fern continued to weaken to a tropical depression on December 30. Both agencies stopped advisories later on the same day.
Two active monsoon troughs that also developed Typhoon Fern and Southern Hemisphere Cyclones Ophelia, Phil, and Fergus spawned Tropical Depression 43W in the South China Sea on December 21. Due to the troughs' nature, the depression headed east-southeastward, where it strengthened into the final tropical storm of the year on the 24th; Greg. After reaching a peak of 45 knots (83 km/h) winds it crossed the northern part of Borneo on the 25th. It continued east-southeastward until dissipation on the 27th, south of the Philippines. Greg caused extensive property damage on Borneo from torrential flooding, resulting in 127 deaths and 100 people missing.[4]
During the season 30 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list which started in 1996.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. Names not retired from this list will be used again in the 2000 season. This is the same list used for the 1992 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.
This table summarizes all the systems that developed within or moved into the North Pacific Ocean, to the west of the International Date Line during 1996. The tables also provide an overview of a systems intensity, duration, land areas affected and any deaths or damages associated with the system.
