1978 Pacific typhoon season

The 1978 Pacific typhoon season was a very active season that lasted more than a year. It has no official bounds; it ran year-round in 1978, 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 1978 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.

Seasonal summaryEdit

 

33 tropical depressions formed this year in the Western Pacific, of which 29 became tropical storms. 15 storms reached typhoon intensity, of which 1 reached super typhoon strength. Many of the storms either remained at sea or failed to do any damage.

Tropical Depression 28 developed October 15. Three and a half days later, it strengthened into a tropical storm. Rita became a typhoon late on October 19. Rita reached Category 5 status on October 23, reaching a minimum central pressure of 878 millibars, only 8 mb higher than Typhoon Tip's record set in 1979. After spending over three consecutive days at that intensity, Rita weakened to a Category 4 and smashed ashore on Luzon. Rita stayed a typhoon during its entire passage over the Philippines and emerged into the South China Sea as a minimal typhoon. Rita then decayed slowly and dissipated as a depression near the coast of Vietnam. The typhoon caused considerable damage and loss of life in the Philippines, though exact numbers are unknown.

Increased convective activity in the monsoon trough was first noticed on satellite data on November 14 about 690 mi (1110 km) southeast of Truk. On November 16, the disturbance was upgraded to Tropical Depression 33. Based on an improved satellite signature, TD 33 was upgraded to Tropical Storm Viola at 1200 UTC November 17.[3] Viola continued to intensify as the storm moved on a northwestward track.[9] Late on November 19 reconnaissance aircraft confirmed that Viola's surface pressure had fallen to 977 mb; and, that an eye was beginning to form. Early on November 20, Viola was upgraded to a typhoon. Viola then started to rapidly intensify and reached peak intensity on November 21 with winds of 145 mph (230 km/h). Viola recurved away from Luzon on November 22.[3] By the next day, the storm had already weakened to a category 1 and further weakened to a tropical storm. Viola dissipated on November 24.[9]

On the 29th, Winnie reached its peak intensity as severe tropical storm with (10-min) winds of 65 mph (100 km/h). Winnie became extratropical early on November 30.

Tropical Depression GardingEdit

Tropical depression (PAGASA)
  
DurationDecember 13 – December 16
Peak intensity55 km/h (35 mph) (10-min) 

Named by PAGASA.

Storm namesEdit

During the season 28 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 from late 1950. However the JTWC changed their naming scheme by the next year, now including both female and male names.

Nadine Olive Polly Rose Shirley Trix Virginia Wendy Agnes Bonnie Carmen Della Elaine Faye
Gloria Hester Irma Judy Kit Lola Mamie Nina Ora Phyllis Rita Tess Viola Winnie

One name, Susan, developed over the Central Pacific and was named from this list. The storm never became a part of the West Pacific basin.

PhilippinesEdit

Akang Bising Klaring Deling Emang
Gading Heling Iliang Loleng Miding
Norming Oyang Pasing Ruping Susang
Tering Uding Weling Yaning
Auxiliary list
Aning
Bidang Kading Delang Esang Garding

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 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1982 season. This is the same list used for the 1974 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.

RetirementEdit

Due to extreme damages and death toll caused by Typhoon Rita (Kading), PAGASA retired the name Kading in its auxiliary list. The name replaced was Katring.
