1984 Pacific typhoon season
From Wikipedia, the free encyclopedia
The 1984 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 1984 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.

[edit] Storms
30 tropical depressions formed this year in the Western Pacific, of which 27 became tropical storms. 16 storms reached typhoon intensity, of which 2 reached super typhoon strength.
[edit] Tropical Storm Vernon
Tropical Storm Vernon, the first of the year, developed in the South China Sea on June 7. It moved inland on the 10th, and caused little damage. What makes this storm notable is that, combined with last year's late formation of Tropical Storm Sarah in June, this is first and only time that 2 consecutive years had their first storm develop in June.

- Main article: Typhoon Ike
Typhoon Ike caused extreme wind and flooding damage when it crossed the Philippines, resulting in 1039 fatalities (with 1147 missing and presumed dead), one of the Philippines' worst natural disaster in modern times. In addition, 200,000 to 480,000 were left homeless, and extensive crop damage was experienced in southern China. The name Ike was retired after this season.
[edit] Tropical Storm June
When 50 mph Tropical Storm June hit southeast China on August 30, 67 people were reported dead due to extensive flooding from June's broad circulation.
[edit] Tropical Storm Susan
Extreme flooding from Tropical Storm Susan hitting eastern Vietnam on October 12 caused 33 casualties and moderate crop damage.
[edit] Super Typhoon Vanessa
Super Typhoon Vanessa was the strongest typhoon of the season, reaching wind speeds of 185 mph over the open waters of the West Pacific. At its peak, it had a pressure of 879 mb, only 9 millibars higher than the record-setting Typhoon Tip of 1979.
[edit] Typhoon Agnes
Two months after Typhoon Ike hit the central Philippines, 140 mph Typhoon Agnes hit the same area on the 4th. It crossed the islands, and hit eastern Vietnam as a 115 mph typhoon on the 7th. Agnes rapidly weakened, after causing over 564 casualties and $30 million (1984 USD) in damage.
[edit] Super Typhoon Bill
An area of convection organized into a tropical depression on November 8 while east of Guam. It executed a small loop, reached tropical storm strength later on the 8th, and reached typhoon intensity on the 11th. Bill continued to strengthen as it tracked westward, reaching maximum sustained winds of 150 mph on the 14th. Strong upper level winds weakened the storm, and as a break in the subtropical ridge brought the storm northward, upper level winds from Typhoon Clara weakened Bill to a tropical storm on the 18th. It looped southeastward while just east of Luzon, and looped again to the southwest on the 20th. Bill lost his losing battle on the 22nd, after causing minor damage on its path.
[edit] 1984 storm names
Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center. The first storm of 1984 was named Vernon and the final one was named Doyle. The name Ike was retired after this season.
