Good question. Hurricanes is the name given to the strongest storms in the Atlantic ocean and eastern Pacific Ocean east of the Dateline. Cyclone is the name given to the same kind of storm that forms in the Indian Ocean. Tornadoes are called cyclones because in the northern hemisphere they have cyclonic flow of air within them or counter-clockwise flow. The major differences between the former and the latter are where they form, their time and space scales of motion, and their thermal structure. Tornadoes are much smaller and last less time and cover less ground. Hope this helps a bit.

A cyclone is a regional event of considerable size. A tornado is a local event. Tornadoes accompany severe storm cells, usually occur along the front, i.e. the direction the storm cell is moving, I believe.

Hurricane is a name for cyclones that occur in the SE USA, mid-Atlantic, Western Mexico and Central American nations and all the island nations and places thereabouts.

Typhoon is a name for cyclones that occur in Pacific Ocean off Philippines, China, Japan, northern Pacific, and all those WWII islands, etc.

Cyclone is a name for cyclones that hit Australia, India. Tornadoes are often associated with cyclones.

One recent hurricane spawned about 30 tornadoes in the SE USA.

All of these phenomena involve high speed winds. But in a tornado the winds are traveling in a high speed vortex. A tornado usually has a short, but very destructive duration. Winds can approach 275 mph.... Hurricane winds are not as strong, but they still do great damage as they take their sweet time pounding you for a much longer duration. Winds greater than 75 mph. Typical hurricanes have many 100mph gusts. Sometimes worse for the biggies...150+

Tornadoes usually revolve counterclockwise in the USA, but occasionally there is a clockwise tornado. Hurricanes revolve counterclockwise. Actually, it is the winds that are moving that way, pushing the clouds and rain.... Storm surge follows the NE edge of the hurricane, rotating CCW. I think cyclones south of the equator move clockwise, same for any tornadoes there (most of the time).

A tornado hit London recently. USA is not the only place. Some occur in Holland. Waterspouts are tornadoes on the water. Good to stay out of !!! especially if you have a sailboat or small boat. Can suck up fish and rain the fish on land. That has also happened in England. There have been raining frogs reports too.

A really big Typhoon is the worst of all. A 'small, tight' hurricane eye is worse than a big eye. The winds at the center (eye wall) are much more ferocious.

On the more absolute, but less visible level, hurricanes transfer heat energy from the sea to the far upper atmosphere (hurricane winds exit clockwise at the top) where the heat can be radiated to outer space. Thus they are a vital cooling mechaniism. Tornadoes are not so powerful in the larger aspect, but do serve also to transfer heat from hot to cold air in the nearer upper atmosphere. Most of the transfer is between air masses. When heat is given up this way, heavy rains accompany a hurricane and hail accompanies a tornado. There are strong winds in both, much turbulence as for thunderstorms, only more powerful. Hail and tornadoes can occur during a hurricane. Rain and hail accompany both. But a hurricane mostly produces extreme winds and heavy rains. The eye itself is a relative zone of quiet, often fooling people into believing the worst is over -- and then they are hit by winds from the opposite direction, equally ferocious, followed by the last half of the hurricane.

Tropical revolving storms are called hurricanes in the Atlantic and eastern Pacific oceans; typhoons in the South China Sea; and tropical cyclones in the Indian and south Pacific oceans. The correct name is "tropical cyclone" but this is often abbreviated to "cyclone". Technically, any low pressure system is a cyclone just as any high pressure system is an anticyclone. These are synoptic scale systems that form in the tropics. They can be hundreds of kilometres in diameter and can last from days to weeks. These storms can be destructive over large areas.

Tornadoes are vortices that extend from severe thunderstorms to the ground. They are tens of metres in diameter and last only for minutes. 30 minutes would be a long life for a tornado. Tornadoes have been recorded in every country, they are not restricted to the tropics. Tornadoes can be very destructive over small areas and windspeeds in tornadoes are often higher than those in hurricanes.

The formation of tropical revolving storms and tornadoes is entirely different.

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)

sure I agree that those words could be perplexing. first of all Hurricanes, Typhoons and Cyclones are each of an analogous. all of them are available from the sea and are powered by utilising the warmth waters, as a result why we don't get them interior the united kingdom. Hurricanes are what English human beings call them. Typhoons are jap and Cyclones are the different Asians. Tornadoes are thoroughly distinctive they arrive while warm air and funky air meet and puncture a layer above and then a tornado starts to seem and come out of the clouds and hits the Earth Please don't get mixed up between those 2 they're like opposites to a minimum of one yet another.

tropical storms are called different names . hurricanes develop over the Atlantic , typhoons over the Pacific , and cyclones over the Indian ocean .

Let's not forget that in Australia they are often referred to as "willy-willies" in slang. Officially they are referred to as Tropical Cyclones.
