Hurricane
Hurricane
Hurricane (/ˈhʌrɪkən, -keɪn/) is a powerful tropical cyclone that forms over warm ocean waters. The term is derived from the Spanish word 'huracán', which in turn was borrowed from the Taino Native American word 'hurakán', meaning 'god of the storm'.
Definition
A hurricane is a type of tropical cyclone with sustained winds that have reached speeds of 74 mph (119 km/h) or higher. Hurricanes are characterized by a low-pressure center known as the "eye", strong winds and spiral arrangements of thunderstorms that produce heavy rain.
Classification
Hurricanes are classified into five categories based on their wind speed and potential for damage, using the Saffir-Simpson Hurricane Wind Scale. Category 1 is the weakest with winds from 74 to 95 mph, while Category 5 is the strongest with winds exceeding 156 mph.
Formation
Hurricanes form over warm ocean waters near the equator. When the warm, moist air rises, it creates an area of low pressure beneath. Air from surrounding areas rushes in, creating strong winds. The system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface.
Effects
The effects of a hurricane can be devastating and include high winds, heavy rain, storm surge, tornadoes, and flooding. These effects can lead to loss of life, property damage, and economic disruption.
