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. [ 5 ]
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]
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.
The strongest hurricane to reach land was the Labor Day Hurricane of 1935 (892 hPa). [12] The deadliest hurricane was the Great Hurricane of 1780 (22,000 fatalities). [54] The deadliest hurricane to make landfall on the continental United States was the Galveston Hurricane in 1900, which may have killed up to 12,000 people. [55]
Cyclone vs. hurricane vs. typhoon: These are all terms used to name the same type of tropical storms, it just depends what ocean the storm is in. In the Atlantic and Eastern Pacific Ocean, a storm ...
All hurricanes in the northern hemisphere have one thing in common: they spin counterclockwise. The direction is caused by the Coriolis effect.
Traditionally, areas of tropical cyclone formation are divided into seven basins. These include the North Atlantic Ocean, the eastern and western parts of the North Pacific Ocean, the Southwest Pacific, the Southwest and Southeast Indian Oceans, and the North Indian Ocean (Arabian Sea and Bay of Bengal).
A derecho is a widespread thunderstorm complex, but its severity, distance and duration make this weather phenomenon stand out from the more typical spring and summer storms. The term "derecho" is ...
