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.

1944 Pacific typhoon season

Typhoon Cobra was first spotted on December 17, in the Philippine Sea. It sank three US destroyers, killing at least 790 people, before dissipating the next day.

Maximum sustained winds were estimated at 145 MPH which would classify it as a Category 4 typhoon on the Saffir-Simpson Hurricane Scale.

1945 Pacific typhoon season

A small, yet powerful typhoon, Connie, was first spotted on June 1 by the Weather Central Guam, moving northeast. Winds were reported to have been as high as 140 mph. But by June 7, it began to weaken. Its final fate is unknown. One officer and five men were lost or killed because of Connie.

Typhoon Helen formed on August 29. It moved west-northwest and strengthened into a major hurricane with 120 mph winds. It weakened slightly to a category two and struck Taiwan. It briefly was over waters before it hit China as a tropical storm. It dissipated on September 4.

Louise was first seen developing on October 2 in the Caroline Islands. It unexpectedly veered north and slowed down, only to intensify as it passed over Okinawa with 90 mph wind gusts and a minimum central pressure of 968.5 mbar. Shortly after, Louise began to weaken, and hit Japan as a strong tropical storm. The tropical cyclone became extratropical shortly after on October 12. In Okinawa, 36 people died, 47 people were reported missing, and 100 people were seriously injured. In Buckner Bay, 30-35 waves were reported to have crashed ashore, tearing into the Quonset huts and other building. 12 ships were sunk, 222 ships were grounded, and another 32 were severely damaged. 80% of the buildings in the bay were completely wiped out while all 60 airplanes at the local airports were damaged, but most were repairable. 107 amphibious craft (including the wrecking of four tank landing ships, two medium landing ships, a gunboat, and two infantry landing craft) were grounded and damaged.

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.

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 thestorm.
