Typhoons form in the tropical oceans when areas of high pressure rush toward areas of low pressure, which creates wind. When the storm begins to rotate and organize around an "eye" of low pressure, it is well on its way ... More »

Like other tropical cyclones, typhoons form when warm, calm ocean waters transfer warmth and moisture to the air above the surface. The air rises into cooler layers of the atmosphere, allowing the water to condense and t... More »

Tropical cyclones, including hurricanes and typhoons, form when calm, warm ocean waters set up a spiraling convection current in the air above the surface. As warm, moist air rises, cooler air moves in to replace it, cre... More »

A typhoon develops from the combination of a warm sea surface, atmospheric turmoil, intense humidity, enough Coriolis force to create a low pressure center, low vertical wind shear, and an already existing low level focu... More »

A monsoon is a seasonal reversal of wind, while a hurricane is an organized storm with very low pressure. Monsoons typically occur in Southeast Asia and Australia, as well as Western Africa. By contrast, hurricanes occur... More »

Whether it's a bathtub draining or a spinning tornado, vortexes are caused by downdrafts that form when high pressure and low pressure interact. The conflict results in the creation of a swirling suction that, in the cas... More »

Hurricanes are made when tropical storms form over sections of the ocean with warm, moist air and enough wind to begin a spiral. The primary cause is the latent heat from water evaporating off the surface of the ocean, w... More »
