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.

This was the first hurricane ever reported in the Atlantic, south of the equator. September 7–9, 2004 – Hurricane Ivan parallels the north coast of Venezuela as a Category 4 hurricane. Ivan's strong winds forced the closure of several airports. The hurricane also produced heavy rainfall and strong waves. [37]
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]
The line-crossing ceremony is an initiation rite in some English-speaking countries that commemorates a person's first crossing of the Equator. [1] The tradition may have originated with ceremonies when passing headlands, and become a "folly" sanctioned as a boost to morale, [2] or have been created as a test for seasoned sailors to ensure their new shipmates were capable of handling long ...
The ecology of the Caribbean is tropical because of its proximity to the equator with warm temperatures that result in a humid climate. There are many ecosystems in the Caribbean with a multitude of tropical plants, trees and animals. When a hurricane passes over an island, it brings usually heavy rainfall and strong winds.
Tropical Storm Hilary swirled northward Sunday just off the coast of Mexico's Baja California peninsula, no longer a hurricane but still carrying so much rain that forecasters said “catastrophic ...
Hurricane Otis slammed into Mexico early on Wednesday as the strongest-ever storm to make landfall on the country’s west coast. Otis went from a Category 1 to Category 5 hurricane in only 12 ...
The precise location of the equator is not truly fixed; the true equatorial plane is perpendicular to the Earth's rotation axis, which drifts about 9 metres (30 ft) during a year. Geological samples show that the equator significantly changed positions between 48 and 12 million years ago, as sediment deposited by ocean thermal currents at the ...
