    A hurricane is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 119 km/hr (74 mph). It forms and intensifies over tropical oceanic regions.

    Hurricanes are generally smaller than storms in mid-latitudes, typically about 500 km (311 miles) in diameter. At the ocean’s surface, the air spirals inward in a counterclockwise direction. This cyclonic circulation becomes weaker with height, eventually turning into clockwise (anticyclonic) outflow near the top of the storm.

    A hurricane is a type of tropical cyclone, which is a generic term for a low pressure system that generally forms in the tropics. The cyclone is accompanied by thunderstorms and, in the Northern Hemisphere, a counterclockwise circulation of winds near the earth's surface. Tropical cyclones are classified as follows:

    * Sustained winds

    A 1-minute average wind measured at about 33 ft (10 meters) above the surface.

    ** 1 knot = 1 nautical mile per hour or 1.15 statute miles per hour. Abbreviated as "kt".

    Tropical Depression

    An organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds* of 38 mph (33 kt**) or less

    Tropical Storm

    An organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds of 39-73 mph (34-63 kt)

    Hurricane

    An intense tropical weather system of strong thunderstorms with a well-defined surface circulation and maximum sustained winds of 74 mph (64 kt) or higher

    Hurricanes are categorized according to the strength of their winds using the Saffir-Simpson Hurricane Scale. A Category 1 storm has the lowest wind speeds, while a Category 5 hurricane has the strongest. These are relative terms, because lower category storms can sometimes inflict greater damage than higher category storms, depending on where they strike and the particular hazards they bring. In fact, tropical storms can also produce significant damage and loss of life, mainly due to flooding.

    Hurricane Names

    When the the winds from these storms reach 39 mph (34 kts), the cyclones are given names. Years ago, an international committee developed names for Atlantic cyclones (The History of Naming Hurricanes). In 1979 a six year rotating list of Atlantic storm names was adopted — alternating between male and female hurricane names. Storm names are used to facilitate geographic referencing, for warning services, for legal issues, and to reduce confusion when two or more tropical cyclones occur at the same time. Through a vote of the World Meteorological Organization Region IV Subcommittee, Atlantic cyclone names are retired usually when hurricanes result in substantial damage or death or for other special circumstances. The names assigned for the next several seasons are shown below.

    A hurricane is a violent, tropical, cyclonic storm of the western North Atlantic, having wind speeds of or in excess of 72 mph (32 m/sec).

  • 1 decade ago

    a severe tropical storm with torrential rain and extremely strong winds. hurricanes originate in areas of low pressure equatorial regions of the atlantic or caribbean, and then strengthen, traveling northwest, north, or north east. High Winds: a wind of above 119 km/74 miles per hour, classified as force 12 or above on the beaufort scale. Fast and Forceful person or thing: somebody or something resembling a violent storm in force, speed, or effect.

    Hurricane: a severe tropical cyclone usually with heavy rains and winds moving a 73-136 knots

    there are many kinds of hurricanes but the 2 most basic are cyclonic and anti-cyclonic hurricanes. There has to be warm body of water for them to be possible, so they only happen in the east coast and south east coasts as well as island areas. They die when they reach ground because they don't have the energy from the water that they need.

    I was always told it was a huge storm that only grew on the water and usually struck just places by the sea but, it can come farther inland! It is usually started like a tornado starts with the cold air coliding with the warm air. Sorry im not very good at explaning thing but i hope this helped!
