1983 Pacific typhoon season
Encyclopedia : 1 : 19 : 198 : 1983 Pacific typhoon season
The 1983 Pacific typhoon season has no official bounds, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
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 1983 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. This can often result in the same storm having two names.
Storms
24 tropical depressions formed this year in the Western Pacific, of which 23 became tropical storms. 12 storms reached typhoon intensity, of which 4 reached super typhoon strength.Tropical Storm Sarah
When Tropical Storm Sarah formed in the South China Sea on June 24, it became the latest start of a season since 1973. Sarah moved northwestward, hit Vietnam, and dissipated on the 26th.Typhoon Vera
The monsoon trough spawned a tropical depression on July 12, east of the Philippines. It headed westward, strengthening to a tropical storm that night and a typhoon on the 13th. Vera made landfall on the 14th as an 85 mph typhoon, weakened over the islands, and restrengthened over the South China Sea to a 100 mph typhoon. Vera struck Hainan Island on the 17th, crossed the Gulf of Tonkin, and dissipated over Vietnam on the 18th. Vera brought torrential flooding, resulting in the deaths of over 100 people.
Super Typhoon Forrest
-->
Super Typhoon Forrest developed in the Western Pacific Ocean in September over the open ocean. At the time it was the fastest-developing tropical cyclone on record, with a pressure drop of 92 mbar in a 24 hour period, a record nearly broken by Hurricane Wilma in 2005. Forrest struck Japan as a tropical storm on the 28th, causing 21 casualties and moderate damage.
Tropical Storm Kim
- Main article: Tropical Storm Kim (1983)
45 mph Tropical Storm Kim, which formed in the South China Sea on October 14, hit southeastern Vietnam late on the 16th. It weakened over land, but retained its circulation, and redeveloped into a tropical depression on the 19th in the northeastern Bay of Bengal in the North Indian Ocean. Kim continued northwestward, and dissipated on the 20th over Myanmar. Kim, though a weak storm, caused 200 fatalities and extensive crop damage from heavy rainfall.
Typhoon Lex
Hundreds of people were killed when Tropical Storm Lex, downgraded from a typhoon, hit eastern Vietnam on October 26.Typhoon Orchid
A tropical disturbance organized into a tropical depression on November 14 over the open West Pacific. It tracked southwestward then westward, slowly organizing into a tropical storm on the 17th. Orchid's motion became erratic, and it drifted northward, always remaining within 850 nautical miles of Typhoon Percy, a slow moving typhoon in the South China Sea. Orchid reached her peak of 145 mph winds on the 23rd, before vertical shear caused it to weaken. The storm turned southward, where it dissipated on the 27th. Though the storm was fairly close to the Philippines, no damage was reported. However, an intra-island ferry capsized, resulting in the deaths of 167 passengers.1983 storm names
Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center. The first storm of 1983 was named Sarah and the final one was named Thelma.
