Hurricane Norma (1974)
The 1974 Pacific hurricane season featured one of the most active periods of tropical cyclones on record with five storms existing simultaneously. The season officially started May 15 in the eastern Pacific, and June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean. With 17 named storms and 11 hurricanes, this season was slightly above average. An additional tropical storm formed in the Central Pacific as well. The year also featured a period where six systems, Ione, Olive, Kirsten, Lorraine, Joyce, and Maggie, were all active at once on August 26, a very unusual occurrence. At the time, Olive was a Central Pacific storm that had weakened to a tropical depression while the other five were of at least tropical storm intensity simultaneously and remained so until early on August 27. Five storms were also active between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 current editor-in-chief is Ron McTaggart-Cowan (Environment and Climate Change Canada). History Source: The journal was first published in January 1873 by the United States Army Signal Corps, but issues were later extended back to the start of the federal government's fiscal year (July 1872). It was issued by the Office of the Chief Signal Officer 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 Burea ...

1970 Pacific Hurricane Season
The 1970 Pacific hurricane season was an active Northern hemisphere hurricane season, especially during its early months. It officially started on May 15, 1970, in the eastern Pacific Ocean (east of 140°W), and on June 1, 1970, in the central Pacific (between 140°W and the International Date Line). It ended on November 30, 1970, in both regions. These dates conventionally delimit the period of each year when most tropical cyclogenesis occurs in these parts of the Pacific. This season had an above average number of storms. There were 21 tropical cyclones, of which 18 reached tropical storm strength. Four storms became hurricanes, of which none reached major hurricane strength. In the central Pacific, one hurricane and one tropical depression formed. One of the depressions crossed the Date Line to become a typhoon in the western Pacific. __TOC__ Systems Hurricane Adele An area of low pressure lacked strong convection until May 30, when it s ...

NOAA
The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone. The agency is part of the United States Department of Commerce and is headquartered in Silver Spring, Maryland. History NOAA traces its history back to multiple agencies, some of which are among the earliest in the federal government: * United States Coast and Geodetic Survey, formed in 1807 * Weather Bureau of the United States, formed in 1870 * Bureau of Commercial Fisheries, formed in 1871 (research fleet only) * Coast and Geodetic Survey Corps, formed in 1917 The most direct predecessor of NOAA was the Environmental Science Services Administration (ESSA), into which several existing scientific agencies such as the ...

HURDAT
The Hurricane Databases (HURDAT), managed by the National Hurricane Center (NHC), are two separate databases that contain details on tropical cyclones that have occurred within the Atlantic Ocean and Eastern Pacific Ocean since 1851 and 1949 respectively. The Eastern Pacific database was originally compiled at the NHC during 1976 to help with the initialization with two tropical cyclone forecast models. Initially, tracks for the Central Pacific region and tracks for tropical depressions that did not develop into tropical storms or hurricanes were not included within the database. Over the next few years tracks were archived best track data from the Eastern Pacific Hurricane Center (EPHC) were archived by the NHC on an annual basis. During 1982, the NHC started to include data on Central Pacific tropical storms and hurricanes within the database, before they took over the responsibility for issuing advisories during 1988. The format of the Eastern Pacific database was subsequently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Placencia
Placencia is a small village located in the Stann Creek District of Belize. History Prior to the European colonization of the Americas, the Placencia Peninsula was inhabited by the Maya peoples, Maya. Archaeological evidence suggests that the Maya in this area produced salt and traded it with other settlements along the coast. In the 17th century, Placencia was settled by English Puritans, originally from Nova Scotia and Providence Island colony, Providence Island. This settlement died out during the Spanish American wars of independence in the 1820s. The Placencia Peninsula was resettled in the late 1800s by several families. Placencia prospered and soon became a village, earning its livelihood from the sea. The Spaniards that traveled the southern coast of Belize gave Placencia its name.

Fujiwhara Interaction
The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiwara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one. Extratropical cyclones typically engage in binary interaction when within of one another, while tropical cyclones typically interact within of each other. Description When cyclones are in proximity of one another, their centers will circle each other cyclonically (counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere) about a point between the two systems due to their cyclonic wind circulations. The two vortices will be attract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
