Cyclones, which are storms that rotate around a central low-pressure area, occur when high-pressure cold air fronts slide on top of low-pressure warm air fronts. When the warm air rises, cold air on all sides drops, and ...

A cyclone is formed when a system of winds moving in circular motion closes in toward an area of the sea with low atmospheric pressure. The formation of cyclones occurs in four stages including formative, immature cyclon...

A tropical cyclone occurs when calm, warm seas provide heat and moisture to surface air, causing it to rise into the stratosphere. As the air cools, it deposits moisture and falls, creating a convection current. This cyc...

Hurricanes occur because during the summer months, warm air over the ocean rises to leave an area of low pressure, into which cool air immediately flows. This air too warms up and rises, and new pockets of cool air take ...

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...

Tropical cyclones form when warm ocean waters heat the air above, causing it to rise and create a low pressure zone. As more air flows in from outside this region, it warms, flows upward and deposits moisture in the form...
