The terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone". A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).
Tropical cyclones with maximum sustained surface winds of less than 17 m/s (34 kt, 39 mph) are called "tropical depressions" (This is not to be confused with the condition mid-latitude people get during a long, cold and grey winter wishing they could be closer to the equator ;-)). Once the tropical cyclone reaches winds of at least 17 m/s (34 kt, 39 mph) they are typically called a "tropical storm" and assigned a name. If winds reach 33 m/s (64 kt, 74 mph)), then they are called:
"hurricane" -- (the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E)
"typhoon" -- (the Northwest Pacific Ocean west of the dateline)
"severe tropical cyclone" -- (the Southwest Pacific Ocean west of 160E or Southeast Indian Ocean east of 90E)
"severe cyclonic storm" -- (the North Indian Ocean)
"tropical cyclone" -- (the Southwest Indian Ocean)
(Neumann 1993).

Tornadoes ensue in maximum components of the international. inspite of the incontrovertible fact that they are maximum common over the continental plains of the u . s . a .. Tornadoes are generally pointed out as a funnel of spiraling air descending from the backside of clouds to the earth. The twister is generally narrow, a pair of million/2 km huge and hardly does it pass greater desirable than 20 km. Like hurricanes the right mechanism of ways the funnel varieties in no longer understood. hurricane Tropical Storms start up interior 8º and 15º north and south of the equator the place floor sea temperatures attain 27ºC. The air above the warmth sea is heated and rises. This motives low rigidity. the climate gadget generates warmth which powers the hurricane, inflicting wind speeds to strengthen. This motives the Tropical hurricane to take care of itself. Tropical storms count on a lot of heat, moist air from the sea - simply by fact of this they die out over land. The proper area of the tropical hurricane is conventional simply by fact the attention. the attention is generally between 30-50km for the period of. that's an area of calm, with easy winds and no rain. It includes descending air. great cumulonimbus clouds embody the attention. those are brought about by skill of moist air condensing because it rises. Wind speeds nicely-known 160km in line with hour around the attention.

Different parts of the world, same storm.
