*GET THIS CLEAR BEFORE U READ BELOW A TYPHOON OR A HURRICAN IS A TROPICAL CYCLONE The formation of typhoons is the topic of extensive ongoing research, and is still not fully understood. Six general factors are necessary to make typhoons formation possible, although typhoons may occasionally form without meeting these conditions: Water temperatures of at least 26.5 �C (80�F)[9] down to a depth of at least 50 m (150 feet). Waters of this temperature cause the overlying atmosphere to be unstable enough to sustain convection and thunderstorms.[10] Rapid cooling with height. This allows the release of latent heat, which is the source of energy in a typhoons.[9] High humidity, especially in the lower-to-mid troposphere. When there is lots of moisture in the atmosphere, conditions are more favourable for disturbances to develop.[9] Low wind shear. When wind shear is high, the convection in a cyclone or disturbance will be disrupted, blowing the system apart.[9] Distance from the equator. This allows the Coriolis force to deflect winds blowing towards the low pressure center, causing a circulation. The approximate distance is 500 km (310 miles) or about 5 degrees from the equator.[9] A pre-existing system of disturbed weather. The system must have some sort of circulation as well as a low pressure center.[9] Generally, Tropical cyclones can only form from three different types of systems: tropical waves, non-tropical lows and decaying frontal boundaries. Tropical cyclones form most often from tropical waves, also called easterly waves, which, as mentioned above, are westward moving areas of convergent winds. Tropical waves often carry with them thunderstorms, which can develop into tropical cyclones. A similar phenomenon to tropical waves are West African disturbance lines, which are squalls that form over Africa and move into the Atlantic, often as a part of the Intertropical Convergence Zone. Tropical cyclones also frequently form from upper tropospheric troughs, which are cold-core upper level lows. A warm-core tropical cyclone may result when one of these works down to the lower levels and produces deep convection. Off-season tropical cyclones most often form in this manner. Finally, decaying frontal boundaries may occasionally stall over warm waters and produce lines of active convection. If a low-level circulation forms under this convection, it may develop into a tropical cyclone.

OK, first of all Rachelle, you need to just shut up because that is pretty much what this site is for DUH!! Second, Ruby, if you know, stop saying you know and answer the freak'in question!I don't even think that you know the answer!! And the answer: Typhoons start off as tropical thunderstorms. The strong winds pull in moisture from the oceans. The thunderstorms convert the moisture into heat. The heat causes more air to flow to the center of the storm which causes more evaporation. All the heat and air flow towards the eye creating the typhoon. Good question. Stupid answers all the rest of you. :) Listen, you need to just answer questions when people ask them OK you dumb people?? All Love, Whatever

Typhoons are a type of highly destructive low pressure systems which generally form in the tropics. They form 10 degrees or more from the equator where the Coriolis effect is strongest. The high temperatures of the tropics evaporate lots of moisture into the air, forming clouds which then build up and start swirling from the Coriolis effect.

Typhoons are formed over high pressure systems, in very cold areas, over large masses of land. These conditions cause the extremely rapid formation of this slow process.

The warm and humid air is the energy source for typhoons. While jet streams (high level winds) are moving through the ocean, normal winds hit them. The two winds intertwine, causing it to spin because of the Earth rotation. Like the hurricane wind blows above the typhoon making it move along the ground (water). As the typhoon travels it grows by collecting water vapor and warm air.

typhoons are formed when warm air collides with cool air. they spin in a counter clockwise direction.
