1940 Pacific Hurricane Season
The 1940 Pacific hurricane season ran through the summer and fall of 1940. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. During this season, there is a former typhoon that crossed into central north Pacific. Systems Hurricane One Late on June 17, west-northwest of Acapulco and close to the coast of Mexico, an area of thunderstorms formed into a tropical cyclone. The system was very small, and eventually became a hurricane. It headed west-northwest or northwest, and was last detected early on June 18. A ship in the eye measured a pressure of . Tropical Storm Two On July 20, a tropical depression was observed southwest of Acapulco. Historical Weather Maps show this depression near 17N 102W. It intensified into a tropical storm on July 21, tracked northwest, and dissipated on July 24. A depression/remnant low was tracked until July 26. The low was last seen near 24N 129W ...

1938 Pacific Hurricane Season
The 1938 Pacific hurricane season ran through the summer and fall of 1938. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. However, 1938 saw an unusually active season, with numerous tropical cyclones forming in January and a hurricane struck Northern California in February, killing five people. On August 18, Cyclone Mokapu caused record August rainfall, and a record low pressure when it struck Hawaiian Islands. It brought down power lines and damages into a plantation. Systems Tropical Cyclone One and Two Two tropical cyclones existed in January, one near the International dateline and another near the Revillagigedo Islands The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of C .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1939 Pacific Hurricane Season
The 1939 Pacific hurricane season ran through the summer and fall of 1939. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. However, 1939 saw a large number of storms threaten California. Systems Hurricane One On June 12, a hurricane was detected. The lowest pressure reported by a ship was . The hurricane was last seen June 13. Possible Tropical Cyclone Two A possible tropical cyclone was located off the coast of Mexico on June 27. A ship reported a gale and a pressure of . The system was last seen on June 28. Tropical Cyclone Three On July 19, a tropical cyclone was detected. A ship reported a pressure of . Tropical Cyclone Four On July 29, a tropical cyclone was located midway between Manzanillo and Acapulco. It moved up the coast, and a ship reported a pressure of on July 29 as the cyclone made landfall in the vicinity of Manzanillo. Tropical Cyclone Five A small ...

1941 Pacific Hurricane Season
The 1941 Pacific hurricane season ran through the summer and fall of 1941. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. 1941 season was the last season before ''Monthly Weather Review'' stopped publishing temporarily due to World War II. 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] |
1942–48 Pacific Hurricane Seasons
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

Weather Satellite
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator). While primarily used to detect the development and movement of storm systems and other cloud patterns, meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, and energy flows. Other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El Niño and its effects on weather are monitored ...

Monthly Weather Review
The ''Monthly Weather Review'' is a peer-reviewed scientific journal published by the American Meteorological Society. It covers research related to analysis and prediction of observed and modeled circulations of the atmosphere, including technique development, data assimilation, model validation, and relevant case studies. This includes papers on numerical techniques and data assimilation techniques that apply to the atmosphere and/or ocean environment. The editor-in-chief is David M. Schultz (University of Manchester). History The journal was established in July 1872 by the United States Army Signal Corps. It was issued by the Office of the Chief Signal Officer from 1872 until 1891. In 1891, the Signal Office's meteorological responsibilities were transferred to the Weather Bureau under the United States Department of Agriculture. The Weather Bureau published the journal until 1970 when the Bureau became part of the newly formed National Oceanic and Atmospheric Administration, ...

High Pressure Area
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation. The strongest high-pressure areas result from masses of cold air which spread out from polar regions into cool neighboring regions. These highs weaken once they extend out over warmer bodies of water. Weaker—but more frequently occurring—are high-pressure areas caused by atmospheric subsidence: Air becomes cool enough to precipitate out its water vapor, and large masses of cooler, drier air descend from above. Within high-pressure areas, winds flow from where the pressure is highest, at the center of the area, toward the periphery where the pressure is lower. However, if the planet is rotating, the straight direction of the air flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940 Pacific Typhoon Season
The 1940 Pacific typhoon season marked an interruption in meteorological records in both the Philippines and Hong Kong due to the start of World War II. There were 43 reported tropical cyclones, including 27 that attained typhoon status. The first storm was observed in February, and the first typhoon formed two months later, killing three people along Mindanao. Several storms formed in June and July, including reports of a typhoon in the newspapers that killed 52 in South Korea, and another typhoon reported in newspapers that killed one person on Samar after dropping heavy rainfall. The strongest typhoon of the season originated in July and attained a minimum pressure of , as reported by a ship northeast of the Philippines. On August 18, a typhoon moved near or over northeastern Luzon, killing nine people. In early September, a typhoon passed through the Bonin Islands south of Japan and later moved near Kyushu; heavy rainfall caused a reservoir to collapse in Ōita Pref ...

Wake Island
Wake Island ( mh, Ānen Kio, translation=island of the kio flower; also known as Wake Atoll) is a coral atoll in the western Pacific Ocean in the northeastern area of the Micronesia subregion, east of Guam, west of Honolulu, southeast of Tokyo and north of Majuro. The island is an unorganized, unincorporated territory belonging to (but not a part of) the United States that is also claimed by the Republic of the Marshall Islands. Wake Island is one of the most isolated islands in the world. The nearest inhabited island is Utirik Atoll in the Marshall Islands, to the southeast. The United States took possession of Wake Island in 1899. One of 14 U.S. insular areas, Wake Island is administered by the United States Air Force under an agreement with the U.S. Department of the Interior. The center of activity on the atoll is at Wake Island Airfield, which is primarily used as a mid-Pacific refueling stop for military aircraft and as an emergency landing area. The runway is the ...

Midway Island
Midway Atoll (colloquial: Midway Islands; haw, Kauihelani, translation=the backbone of heaven; haw, Pihemanu, translation=the loud din of birds, label=none) is a atoll in the North Pacific Ocean. Midway Atoll is an insular area of the United States and is an unorganized and unincorporated territory. The largest island is Sand Island, which has housing and an airstrip. Immediately to the east of Sand Island across the narrow Brooks Channel is Eastern Island, which is uninhabited and no longer has any facilities. Forming a rough, incomplete circle around the two main islands and creating Midway Lagoon is Spit Island, a narrow reef. Roughly equidistant between North America and Asia, Midway is the only island in the Hawaiian Archipelago that is not part of the state of Hawaii. Unlike the other Hawaiian islands, Midway observes Samoa Time ( UTC−11:00, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the Hawaii–Aleutian Time Zone ...

1940 Atlantic Hurricane Season
The 1940 Atlantic hurricane season was a generally average period of tropical cyclogenesis in 1940. Though the season had no official bounds, most tropical cyclone activity occurred during August and September. Throughout the year, fourteen tropical cyclones formed, of which nine reached tropical storm intensity; six were hurricanes. None of the hurricanes reached major hurricane intensity. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. As a result of a reanalysis project which analyzed the season in 2012, an additional hurricane was added to HURDAT. The year's first tropical storm formed on May 19 off the northern coast of Hispaniola. At the time, this was a rare occurrence, as only four other ...

1940s North Indian Ocean Cyclone Seasons
The years between 1940 and 1949 featured the 1940s North Indian Ocean cyclone seasons. Each season was an ongoing event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Below are the most significant cyclones in the time period. Because much of the North Indian coastline is near sea level and prone to flooding, these cyclones can easily kill many with storm surge and flooding. These cyclones are among the deadliest on earth in terms of numbers killed. On 27 April 1949, India Meteorological Department (IMD) became a member of the World Meteorological Organization after independence of India, independence. 1940 season *May 17–25, 1940 – A severe cyclonic storm existed over the Bay of Bengal. *June 23–27, 1940 – A cyclo ...
