1950 Pacific hurricane season : ウィキペディア英語版 | 1950 Pacific hurricane season
The 1950 Pacific hurricane season was notable for one of the storms being the wettest tropical cyclone in United States history. Seven known tropical cyclones occurred during the season, the earliest of which formed on June 14 and the latest of which dissipated on October 3. These dates fall within the range of most Eastern Pacific tropical cyclone activity. ==Season summary== Only seven tropical cyclones were observed in the Eastern Pacific during this season, which is well below the 1995-2008 average of 15 per year. However, it is likely that other tropical cyclones in the Central or Eastern Pacific basin in 1950 went operationally unnoticed, due to small tropical cyclone size, sparse ship reports, relatively unpopulated coastlines, and lack of modern technology. Of the seven tropical cyclones, six attained hurricane status. None of the tropical cyclones became a major hurricane, which is Category 3 or greater on Saffir–Simpson Hurricane Scale. In addition, a tropical cyclone developed within the Central Pacific basin. Similar to 1949, most of the seven tropical cyclones did not differentiate significantly in intensity during the duration, with the exception of Hurricane Hiki and Tropical Storm Five. Although there were no conventional date limits of an Eastern Pacific hurricane season, tropical cyclone activity began almost a month after the dates of the season set in subsequent years, from May 15-November 30. The first tropical cyclone of the season formed mid-June, and two more developed in the month of July. No tropical cyclogenesis occurred for 30 days, and ended with Hurricane Hiki developing on August 12, followed by a quick succession of two more tropical cyclones. No tropical cyclones developed in the Eastern Pacific basin in month of September, records show that this is the only known occurrence of such a meteorological oddity. The season ended after a hurricane developed on October 1 and dissipated two days later.〔
