1940s Pacific Hurricane Seasons
A Pacific hurricane is a mature tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E), while the southern Pacific is divided into 2 sections, the Australian region (90E to 160°E) and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.

International Date Line
The International Date Line (IDL) is an internationally accepted demarcation on the surface of Earth, running between the South and North Poles and serving as the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. Geography Circumnavigating the globe People traveling westward around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line. People traveling eastward must set their clocks: *Forward by one hour for every 15° of longitude crossed, and *Back by 24 hours upon crossing the International Date Line. Failing to do this would make their time inaccurate to the local time. The Arab geographer Abulfed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1933 Pacific Hurricane Season
The 1933 Pacific hurricane season ran through the summer and fall of 1933. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable.

1950 Pacific Hurricane Season
The 1950 Pacific hurricane season was notable for one of the storms being the third-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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1949 Pacific Hurricane Season
The 1949 Pacific hurricane season was the first hurricane season in the Eastern Pacific hurricane database. Six tropical cyclones were known to have existed during the season, of which the first formed on June 11 and the final dissipated on September 30. Another tropical cyclone had formed within the basin in 1949, but was included in the Atlantic hurricane database, had it been classified operationally in the Eastern Pacific basin, would have tallied the overall season to seven tropical cyclones. In addition, there were two tropical cyclones that attained hurricane status, but none of them reached major hurricane intensity (Category 3 or higher on the Saffir–Simpson hurricane scale). Tropical Storm Three threatened the Baja California Peninsula, while an unnumbered hurricane crossed into the Atlantic, later becoming the 1949 Texas hurricane. Season summary Tropical cyclones were recorded in the Eastern Pacific best track database for the first time in 1949. Although officia ...

1942–1948 Pacific Hurricane Seasons
The 1942–48 Pacific hurricane seasons all began during late spring in the northeast Pacific Ocean and the central Pacific. They ended in late fall. Before the satellite age started in the 1960s, data on east Pacific hurricanes is extremely unreliable. In a few years, there are no reported cyclones although many systems certainly formed. 1942 season There are no known tropical cyclones. 1943 season A disturbance developed between the Revillagigedo Islands and the Marias Islands on October 8. It moved rapidly northeastward where it rapidly intensified, reaching pressures as low as . On October 9, as a major hurricane it struck the west coast of Mexico, a short distance south of Mazatlán. The next day, the hurricane dissipated inland. This hurricane caused damage in and around Mazatlán. It sank several vessels. The total cost of damage was $4,500,000 (1943 US dollars), and at least 106 people were killed. 1944 season There are no known tropical cyclones. 1945 season A hurr ...

Systems Tropical Storm One On July 3, a tropical cyclone was spotted, and a pressure of was reported. It possibly headed northeast, towards Cape Corrientes, as a tropical cyclone was spotted in that direction on July 6. However, it is possible that these observations were actually of two different tropical cyclones. Tropical Cyclone Two A tropical cyclone was spotted on July 15, south of Mexico. The next day, another cyclone was spotted further to the west. On July 18, weather possibly associated with a tropical cyclone was reported south of Cabo San Lucas. It is unknown whether either one of these two latter observations are of the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
