This is due to increasing Coriolis force closer to the poles, and which is zero at the equator. [2] [3] [4] One associated phenomenon often seen with low-latitude cyclones is the equatorial westerly wind burst, which allows for sufficient shear vorticity on both sides of the equator to support tropical cyclogenesis.

To put it in perspective, picture yourself standing on the equator, directly south of New York City. In fact, in the United States, this is the one city that has the highest hurricane risk.
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
United States Central Pacific Hurricane Center: Equator northward, African Coast – 140°W Equator northward, 140°W-180 [2] Western Pacific: Japan Meteorological Agency: Equator-60°N, 180-100°E [3] North Indian Ocean: India Meteorological Department: Equator northward, 100°E-45°E: Southern Hemisphere: South-West Indian Ocean: Meteo France ...
A hurricane is a sort of atmospheric engine, spinning about its axis—counterclockwise north of the equator, clockwise south of the equator—thanks to the Coriolis effect, which is caused by the ...
Tropical cyclone observation has been carried out over the past couple of centuries in various ways. The passage of typhoons, hurricanes, as well as other tropical cyclones have been detected by word of mouth from sailors recently coming to port or by radio transmissions from ships at sea, from sediment deposits in near shore estuaries, to the wiping out of cities near the coastline.
The National Hurricane Center’s forecast map Thursday showed five separate lemon-yellow circles for potential storm formation. But none of those storms listed a development potential over 30% ...
The National Hurricane Center is responsible for the region east of 140°W, while the Central Pacific Hurricane Center is responsible for storms forming west of 140°W to the International Date Line. Atlantic hurricane – a tropical cyclone that forms in the Atlantic Ocean. The National Hurricane Center is responsible for the region.
