Pacific typhoon seasons
1988, 1989, 1990, 1991, 1992 |
The 1990 Pacific typhoon season has no official bounds; it ran year-round in 1990, 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.
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 1990 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.
Season summary
Storms
35 tropical cyclones formed this year in the Western Pacific, of which 32 became tropical storms. 18 storms reached typhoon intensity, of which 4 reached super typhoon strength.
Severe Tropical Storm Koryn
| Severe tropical storm (JMA) |

|
|
| Duration |
January 12 – January 17 |
| Peak intensity |
100 km/h (65 mph) (10-min) 980 hPa (mbar) |
On January 12, both the JMA and the JTWC identified a tropical depression in the northwest Pacific Ocean. The depression intensified over the period of a day to become a tropical storm on January 13, when it received the name Koryn from the JTWC. According to them, but not the JMA, Koryn reached hurricane-equivalent strength on January 15, when it peaked in intensity.

The monsoon trough spawned a tropical depression east of the Philippines on June 15. It tracked to the northwest then westward, slowly organizing into a tropical storm on June 18. Ofelia turned more to the northwest and became a typhoon on June 20. Paralleling the east coast of the Philippines, it reached a peak of 100 mph (155 km/h) winds before hitting Taiwan on June 23. Ofelia weakened over the country, and brushed eastern China before dissipating on June 25 near Korea. Ofelia caused heavy flooding throughout its track, resulting in at least 64 casualties.
Typhoon Percy (Klaring)

Typhoon Percy, which developed on June 20, reached a peak of 135 mph winds while located a short distance east of the northern Philippines. Increasing vertical shear weakened Percy to a 95 mph typhoon before crossing extreme northern Luzon on the 27th, an area that felt the effects of Ofelia only days before. It remained a weak typhoon until hitting southeastern China on the 29th before dissipating on the 1st. Percy caused serious damage and flooding in the Carolina Islands and northern Philippines, amounting to 9 deaths.

|
|
| Duration |
August 4 – August 11 |
| Peak intensity |
110 km/h (70 mph) (10-min) 975 hPa (mbar) |
The origins of Winona can be traced back to Severe Tropical Storm Tasha.
On August 2, the remnant low of Tasha, as a patch of thunderstorms over northeastern China, was pushed to the east by a weather front from the west. By August 4, Tasha entered the Yellow Sea, before being pushed south by an anticyclone off northeastern Korea, into the East China Sea.
Although the same system, Tasha was named Winona, as it started to strengthen into a tropical storm by August 7. It reached peak intensity with an eye-like feature on August 8, before landfalling over Japan the next day. Later, the remnants became extratropical.
Typhoon Yancy (Gading)
| Typhoon (JMA) |
| Category 2 typhoon (SSHWS) |
|
|
| Duration |
August 11 – August 23 |
| Peak intensity |
150 km/h (90 mph) (10-min) 950 hPa (mbar) |

|
|
| Duration |
August 15 – August 23 |
| Peak intensity |
140 km/h (85 mph) (10-min) 960 hPa (mbar) |
On August 15, an large area of convection associated with the inflow of
developing Typhoon Yancy was cut off, as Yancy was moving too fast to the west for the convection in the east to be absorbed into Yancy. By August 16, the convection developed a mid to low level circulation, and developed into tropical storm by August 18. Zola intensified into a typhoon by the next day, before reaching peak intensity on August 21. By the next day, Zola made landfall over Japan, before dissipating north of Japan.
High winds and heavy rains produced by the storm killed three people and injured 22 others in Japan.
Typhoon Abe (Heling)
| Typhoon (JMA) |
| Category 2 typhoon (SSHWS) |
|
|
| Duration |
August 23 – September 2 |
| Peak intensity |
140 km/h (85 mph) (10-min) 955 hPa (mbar) |
Forming on August 23 from a tropical disturbance, the depression which would eventually develop into Typhoon Abe initially tracked in a steady west-northwestward direction. As a result of an intense monsoon surge, the system's trajectory briefly changed to an eastward then northward path before returning to its original track. Abe only intensified by a small amount between 0000 UTC August 24 and 0600 UTC August 27 due to the disruptive effects of the surge, and on August 30, Abe peaked in intensity as a Category 2-equivalent typhoon on the Saffir–Simpson hurricane wind scale. After peaking in intensity, Abe crossed the Ryukyu Islands and the East China Sea, making landfall in China where it affected the provinces of Zhejiang and Jiangsu before entering the Yellow Sea, crossing South Korea, and finally transitioning into an extratropical cyclone.[5][6]
Typhoon Abe killed 108–195 people after it caused flooding and landslides in the Philippines and Taiwan, ravaged coastal areas of China, and brought high waves to Japan.[5][7][8] Abe, which is responsible for killing 108 in China, affected half of Zhejiang's land area and a fourth of its population, leaving thousands homeless and causing ¥3.5 billion yuan (RMB, $741.5–743 million USD) to be lost in damages.[6][8][9][10] Additional damage and one fatality occurred in Okinawa Prefecture in Japan, where at least ¥890 million yen (JPY, $6 million USD) in damage was caused.[7][11][12]

A tropical disturbance consolidated into a tropical depression on the 23rd of September to the east of the Philippines. Tropical Storm Gene was named as the storm moved towards the northwest and strengthened into a typhoon the next day. Typhoon Gene reached peak intensity of 95 mph on the 27th shortly before recurving towards the northeast. Gene then skimmed the coasts of Kyūshū, Shikoku and Honshū Islands in Japan before moving out to sea and turning extratropical. Winds on 85 mph were recorded on Kyūshū and heavy rains fell across the region, resulting floods and landslides killed 4 people.[2]

Storm names
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 on mid-1989.

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 1994 season. This is the same list used for the 1986 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.
Retirement
Due to the severity of damage and loss of life caused by Mike, the namewas retired and was replaced with Manny and was first used in the 1993 season. PAGASA also retired the name Ruping for similar reasons and was replaced with Ritang for the 1994 season.
