“– Against the wind hurricane information booklet Three places in your home that are usually damaged by hurricanes are the roof, windows, doors, and there are things that can be done to strengthen these areas to minimise damage.
The warm water heats the air above it, and the updrafts of warm, moist air begin to rise.
Day after day the fluffy cumuli form atop die updrafts.
But the cloud tops rise higher than about 6,000 feet.
As this air swirls in over the sea surface, it soaks up more and more water vapor.
At the storm centre, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapour condenses.
At that height in the tropics, there is usually a layer of warm, dry air that acts like an invisible ceiling or lid.
Once in a while, something happens in the upper air that destroys this lid. But when it it’s the first step in the birth of a hurricane.
As it condenses the drives the upper drafts to heights of 50,000 to 60,000 feet. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads.
The air begins swirling around the storm centre, for the same reason that the air swirls around a tornado centre.
