1940–49 Pacific typhoon seasons

The decade of the 1940s featured the 1940–49 Pacific typhoon seasons. The seasons had 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 1940-1949 Pacific hurricane seasons. 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.

1948 Pacific typhoon season

Typhoon Karen, the strongest cyclone of the season, developed on January 11, well west of the Philippines. It curved westward while slowly intensifying. After a prolonged period of the slow intensification, the tropical cyclone began to rapidly strengthen. It became a super typhoon on January 16. Shortly after, it weakened and dissipated on January 19.

Ophelia formed on June 10 in the South China Sea. It moved west and struck southern China. It dissipated the next day, without attaining maximum sustained winds any higher than 45 mph.

Typhoon Ione struck Japan in mid-September killing 838 people.^[6]

1949 Pacific typhoon season

Typhoon Della struck Japan in mid-June killing 468 people.^[6]

In July, tropical storm Irma killed 1,600 people and destroyed more than 63,000 houses in Shanghai, China, the worst typhoon on record in the city.^[7]

Typhoon Gloria struck Okinawa on July 23. Gloria killed 38 people and destroyed 42,502 buildings on the island. Typhoon Gloria then continued westward and struck Shanghai, China killing 29 people.^[8]

Typhoon Kitty struck the Tokyo/Yokohama area August 31 through September 1, 1949. From reconnaissance reports the maximum sustained winds were near 110 knots 12 hours prior to landfall, but had fallen to minimum typhoon strength by the time it reached Honshū. The death toll reached 123 due to rainfall induced flooding and landslides (NY Times, 9/3/1949), and caused about 15 billion yen in damages. As its center passed near Tokyo, the JMA's Central Meteorological Office was able to launch eight rawindsondes in the typhoon environment. Researcher Dr. Hidedoshi Arakawa was able to analyize these soundings to make a vertical analysis of the storm.^[9]
