Hurricanes?

Katrina, Vince,
Rita are the subject of lead stories in all the journals around the
world. They have created a stir in the North Atlantic Ocean.
Can you guess who
they are...?
No, they are not
some super successful people or any genre of Hollywood stars. They are
the names of hurricanes. Sounds familiar? Do you know what is a
hurricane?
Hurricane is a
tropical cyclone with a speed of around 74 miles per hour
characterized with heavy rains and winds. This is the result of low
pressure system that is usually created around tropical areas. They
are a part of the natural circulation system that moves heat from the
tropical regions to the places of higher altitudes.
Hurricanes are
known by several names in different continents of the world. In the
North Atlantic and South Atlantic region Hurricane is the official
term used for tropical cyclone. The other parts of world in Northwest
Pacific Ocean name hurricane as Typhoon. The hurricanes are called
severe cyclonic storm in the north Indian Ocean.
All these
nomenclatures refer to the similar phenomenon of low pressure in
tropical areas. The only difference between a hurricane and cyclone is
that cyclone is any low pressure atmospheric activity in the southern
hemisphere. Where, hurricane is an atmospheric activity with in the
northern hemisphere of the globe.
Hurricanes are
also called the reverse heat engines. Reason being, they happen due to
the condensation of water around the tropical regions. The
condensation or rising water vapors in air cause a series of reaction
to trigger on the hurricane. As the air heats up around the warm
ocean, the water becomes even warmer. As a result the air moves
towards the ground with heavy thunders carrying the ocean water with
it.
