A hurricane is a tropical cyclone with sustained winds reaching speeds of at least 74 miles per hour, according to The Weather Channel. Hurricanes are classified on a scale of 1 to 5 using the scale Saffir-Simpson hurricane wind scale.Continue Reading
A storm that strengthens over a period of days or weeks is considered a hurricane. The process of hurricane formation starts in the warm, damp air over the tropics, which includes the Caribbean Sea, the Gulf of Mexico, the eastern North Pacific Ocean, the north Atlantic ocean, the east of the International Dateline and the north of the equator. Hurricanes are first categorized as tropical cyclones.
Before a tropical cyclone turns into a hurricane, it passes through four different stages. The first stage is tropical disturbance - a system of clouds, showers and thunderstorms originating in the tropics and staying intact for 24 hours or more. The second stage is tropical depression - a tropical disturbance that develops a closed circulation. The third stage is tropical storm which has maximum sustained one-minute winds of around 39 to 73 miles per hour at an elevation of 10 meters. Finally, the tropical storm becomes a hurricane with sustained one-minute winds of 74 miles per hour at a 10-meter elevation.Learn more about Storms
The winds produced in a tornado can be less than 100 miles per hour, or they can exceed 300 miles per hour. The Enhanced Fujita Scale ranges from EF 0 to EF 5, and this scale is used to estimate the wind damage produced by a tornado.Full Answer >
Hurricanes, typhoons and tropical cyclones all refer to storms in which the winds reach more than 74 miles per hour. The difference in the names refers to the location where the storm originates. A hurricane is confined to the North Atlantic Ocean and the Northeast Pacific Ocean. A typhoon originates in the Northwest Pacific Ocean, and a cyclone occurs in the Indian Ocean, states the Hurricane Research Division of NOAA.Full Answer >
Hurricanes have winds of at least 74 miles per hour, according to NASA. Hurricanes aren't the only storms that produce winds this fast, so these storms are categorized by their combination of fast-moving, swirling winds and rain.Full Answer >
Blizzards are classified as conditions that prevail for three hours or more and include frequent gusts, or sustained winds, of up to 35 miles per hour, along with considerable amounts of blowing or falling snow. These conditions can greatly reduce visibility, sometimes to less than a quarter of a mile.Full Answer >
