Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are unofficially classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minut ...

1970 Atlantic Hurricane Season
The 1970 Atlantic hurricane season was the first year in which reconnaissance aircraft flew into all four quadrants of a tropical cyclone. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season was fairly average, with 14 tropical storms forming, of which seven were hurricanes. Two of those seven became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. The first system, Hurricane Alma, developed on May 17. The storm killed eight people, seven from flooding in Cuba and one from a lightning strike in Florida. In July, Tropical Storm Becky brought minor flooding to Florida and other parts of the Southern United States, leaving one death and about $500,000 (1970 USD) in damage. The most significant storm of the season was Hurricane Celia, a Category 4 hurricane that slammed South Te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1971 Atlantic Hurricane Season
The 1971 Atlantic hurricane season was fairly active with several notable storms. Hurricane Edith, the strongest of the season, was a Category 5 on the Saffir-Simpson scale, the highest category on the scale, even though it was the least intense for that category on record, at 943 mbar. It struck Nicaragua at peak intensity, killing dozens, and later hit southern Louisiana. Until 2003, Hurricane Ginger held the record for the longest known duration of a North Atlantic tropical cyclone, lasting 27.25 days from early September to early October; it is currently the second longest-lasting Atlantic hurricane. Ginger moved ashore in North Carolina, producing heavy rains and damaging winds. An unnamed storm in August attained hurricane status further north than any other Atlantic hurricane. On 11 September, seven tropical cyclones were active at the same time, the record for the Atlantic basin. The season officially began on June 1, and lasted until November 30, 1971; these dat ...

1970 Pacific Hurricane Season
The 1970 Pacific hurricane season began on May 15, 1970 in the east Pacific, and on June 1, 1970 in the central Pacific. It ended on November 30, 1970. These dates conventionally delimit the period of time when tropical cyclones form in the eastern Pacific Ocean. This season had an above average number of storms. There were twenty-one tropical cyclones, of which eighteen 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 dateline to become a typhoon. __TOC__ Systems ImageSize = width:800 height:200 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:01/05/1970 till:01/12/1970 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/05/1970 Colors = id:canvas value:gray(0 ...

1971 Pacific Hurricane Season
The 1971 Pacific hurricane season began on May 15, 1971, in the east Pacific, and on June 1, 1971, in the central Pacific. It ended on November 30, 1971. These dates conventionally delimit the period of time when tropical cyclones form in the east Pacific Ocean. The 1971 season was above average with 18 named storms. Twelve hurricanes formed, of which six became major hurricanes by reaching Category 3 or higher on the Saffir-Simpson Hurricane Scale. At the time, this was a record number of storms. This season had six landfalls (Agatha, Bridget, Katrina, Lily, Olivia and Priscilla), the highest number of landfalling Pacific tropical cyclones in one season. __TOC__ Systems ImageSize = width:800 height:205 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:01/05/1971 till:12/12/1971 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/0 ...

1970 Pacific Typhoon Season
The 1970 Pacific typhoon season has no official bounds; it ran year-round in 1970, 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 Dateline. Storms that form east of the date line and north of the equator are called hurricanes; see 1970 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. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA.

1970 North Indian Ocean Cyclone Season
The 1970 North Indian Ocean cyclone season had no bounds, but tropical cyclones in the North Indian Ocean tend to form between April and December, with peaks in May and November. The 1970 season saw a total of seven cyclonic storms, of which three developed into severe cyclonic storms. The Bay of Bengal was more active than the Arabian Sea during 1970, with all of the three severe cyclonic storms in the season forming there. Unusually, none of the storms in the Arabian Sea made landfall this year. The most significant storm of the season was the Bhola cyclone, which formed in the Bay of Bengal and hit Bangladesh on November 12. The storm killed at least 500,000, making it the deadliest tropical cyclone in recorded history.The world's worst natural disaster ...
