1970–71 South Pacific Cyclone Season
The 1970–71 South Pacific cyclone season, in terms of severe tropical cyclones, was the least active season on record, with none of its six storms strengthening above Category 2 tropical cyclone intensity. It was a below average season, beginning late and ending early. The season officially began on November 15 and ended on April 30, but the first storm formed a month after that, on December 15. __TOC__ Seasonal summary ImageSize = width:825 height:260 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/10/1970 till:01/05/1971 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/10/1970 Colors = id:canvas value:gray(0.88) id:GP value:red id:TDi value:rgb(0,0.52,0.84) legend:Tropical_Disturbance id:TD value:rgb(0.43,0.76,0.92) legend:Tropical_Depression id:C1 value:rgb(0.3,1,1) legend:Category_1_=_63-87_k ...

Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild rain, showers to severe hail, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as Synoptic scale meteorology, large scale (synoptic) Low-pressure area, low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Ea ...

1973 North Indian Ocean Cyclone Season
The 1973 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.

1973 Pacific Typhoon Season
The 1973 Pacific typhoon season, in comparison to the two years preceding it, was a below average season, with only 21 named storms and 12 typhoons forming. However, it featured Typhoon Nora, which ties Typhoon June of 1975 for the second strongest typhoon on record. It has no official bounds; it ran year-round in 1973, 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 1973 Pacific hurricane season. 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.

1973 Pacific Hurricane Season
The 1973 Pacific hurricane season was an above average season, with twelve named tropical cyclones in total. Seven storms became hurricanes, of which three were major (Category 3 or higher on the Saffir-Simpson scale). The season officially started May 15, 1973, in the eastern Pacific, and June 1, 1973, in the central Pacific, and lasted until November 30, 1973. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. All tropical cyclones this season formed in the eastern north Pacific Ocean, often off the coast of Mexico. Most systems traveled generally westward or northwestward, and two reached as far as the waters south of the Hawaiian Islands. The most significant system this year was Hurricane Ava, which was the most intense Pacific hurricane on record at the time. Several other much weaker tropical cyclones came close to, or made landfall on, the Pacific coast of Mexico. Another was Hurricane Ira ...

1972 Pacific Hurricane Season
The 1972 Pacific hurricane season was an ongoing event in tropical cyclone meteorology. There were few notable storms this year. Only one person was killed and storm effects were almost not serious at all. The most notable systems were Hurricane Celeste (1972), Hurricane Celeste and Hurricane Joanne (1972), Joanne. Celeste was the strongest storm of the season, and caused heavy damage to Johnston Atoll. Hurricane Joanne brought gale-force winds to the Continental United States and caused flooding in Arizona and northern Mexico, which killed one person. The only other system to directly impact land was Hurricane Annette. The season began on May 15, 1972, in the east Pacific, and on June 1, 1972, in the central Pacific. It ended on November 30, 1972. These dates conventionally delimit the period of time when tropical cyclones form in the east Pacific Ocean. This season had a below average number of storms. There were twenty tropical cyclones, four of which were in the central Pacifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1973 Atlantic Hurricane Season
The 1973 Atlantic hurricane season was a below average tropical cyclone season overall. Of the 24 tropical or subtropical cyclones which developed, only 8 became named storms, and of those, only 4 became hurricanes, with 1 reaching major hurricane status (Category 3 or higher) on the newly implemented Saffir–Simpson hurricane wind scale. The season officially began on June 1 and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclones form in the North Atlantic. However, the formation of subtropical or tropical cyclones is possible at any time of the year, as demonstrated this season by the formation of multiple pre-season systems, none of which attained storm strength. The first named storm of the year, Hurricane Alice, did not form until July 1. Two of the season's landfalling storms had severe impacts. In August, Hurricane Brenda struck the eastern coast of the Bay of Campeche, killin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1972 Atlantic Hurricane Season
Year 197 ( CXCVII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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.

The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with Weather forecasting, forecasting weather, monitoring oceanic and atmospheric conditions, Hydrography, 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 * National Weather Service, Weather Bureau of the United States, formed in 1870 * United States Fish Commission, Bureau of Commercial Fisheries, formed in 1871 (research fleet only) * NOAA Commissioned Corps, Coast and Geodetic Survey Corps, formed in 1917 The most direct predecessor of NOAA was the Enviro ...
