Typically, tropical cyclones form at least 5.0 degrees of latitude north and south of the equator, or at least 300 nautical miles (556 km, 345 mi) of the equator. Despite the presence of sufficiently warm sea surface temperatures and generally low wind shear , tropical cyclogenesis is uncommon at these latitudes, due to a lack of the Coriolis ...
That's because it formed unusually close to the equator, just 1.4 degrees latitude or about 97 miles north of that line. No other tropical cyclone anywhere on Earth formed or has since formed that ...
Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most tropical cyclone basins. Tropical cyclones on either side of the Equator generally have their origins in the Intertropical Convergence Zone, where winds blow from either the northeast or southeast. [6]
A Category 5 Atlantic hurricane is a tropical cyclone that reaches Category 5 intensity on the Saffir–Simpson hurricane wind scale, within the Atlantic Ocean to the north of the equator. They are among the strongest tropical cyclones that can form on Earth, having 1-minute sustained wind speeds of at least 137 knots (254 km/h ; 158 mph ; 70 m ...
A South American hurricane is a tropical cyclone that affects the continent of South America or its countries. The continent is rarely affected by tropical cyclones, though most storms to hit the area are formed in the North Atlantic Ocean. Typically, strong upper-level winds and its proximity to the equator prevents North Atlantic impacts. [1]
The process is linked to how the Earth's rotation affects winds in tropical regions just away from the equator. ... The proportion of tropical cyclones reaching category four and five may increase ...
In the Indian Ocean north of the equator, tropical cyclones can form throughout the year on either side of the Indian subcontinent, although most frequently between April and June, and between October and December. The North Indian Ocean is the least active official basin, contributing only seven percent of the world's tropical cyclones.
^α Although Luis produced the highest confirmed wave height for a tropical cyclone, it is possible that Hurricane Ivan produced a wave measuring 131 feet (40 m). [41]^β It is believed that reconnaissance aircraft overestimated wind speeds in tropical cyclones from the 1940s to the 1960s, and data from this time period is generally considered unreliable.
