Information About

1981 Pacific Typhoon Season




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 1981 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

29 tropical depressions formed this year in the Western Pacific, of which 28 became tropical storms. 16 storms reached typhoon intensity, of which 2 reached super typhoon strength.


Typhoon Kelly

A tropical disturbance organized into a tropical depression east of the Philippines on June 28 . It tracked westward, reaching tropical storm on the 30th before hitting the central Philippines. Kelly weakened over the islands, but restrengthened in the South China Sea , attaining typhoon status on July 2 . The typhoon hit southern Hainan Island on the 3rd, crossed the Gulf Of Tonkin as a weakening tropical storm, and made landfall on northern Vietnam on the 4th as a 40 mph tropical storm. Kelly dissipated the next day, after causing torrential flooding and mudslides, resulting in 200 casualties and leaving thousands homeless.


Typhoon Clara

The monsoon trough spawned a tropical depression on September 13 well east of the Philippines. The depression moved to the west-northwest, strengthening into a tropical storm on the 16th and a typhoon on the 18th. Clara rapidly intensified to a peak of 140 mph winds on the 19th before brushing northern Luzon on the 19th. Its circulation disrupted, Clara steadily weakened as it continued to the northwest, hitting southeast China on the 21st as an 80 mph typhoon. Clara caused extensive damage and loss of life, leaving thousands homeless from the heavy rains.


Super Typhoon Irma

Super Typhoon Irma developed from the near-equatorial trough on November 17 . As a tropical depression, it headed westward, and steaily intensified, first to a tropical storm on the 19th, later to a typhoon on the 20th. Irma quickly strengthened on the 22nd to a 155 mph super typhoon, but its outflow was disrupted by the Philippines to the southwest. Irma hit the northern Philippines on the 24th as a 95 mph typhoon, and rapidly weakened over the country. As a weakened tropical storm, Irma turned northeastward, where it was absorbed by a cold front on the 27th. More than 200 fatalities and $9 million in damage (1981 USD) can be attributed to the typhoon.


1981 STORM NAMES

Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center . The first storm of 1981 was named Freda and the final one was named Lee. The name Hazen was removed from the list after this season for no particular reason.
