The hurricane

• The formation of a Hurricane:

A hurricane is a really strong tropical depression and his power can be 10 times stronger than the nuclear bomb in 1945.

Hurricanes need special conditions to be formed:

- Upside an ocean that is hotter than 25 degrees on 50 meter deep.

- A high humidity

A hurricane doesn’t born directly hurricane of level 5, it evolve. It begins with the evaporation of the air from the hot water, the hot air rise creates a reduction of the pressure, and the phenomenon of the condensation also appears that creates clouds. The reduction of the pressure and the cloud make a storm.

• What are the risks?

Hurricane surge:

The powerful spiral wind action raises the ocean’s water level and they are the mains causes of the floods they bring.

Floods:

Hurricanes carry a lot of rains even after the end of the hurricanes. This can cause a lot of floods like the hurricanes surge. The floods carry away everything on his way.

Winds:

Many structures are blown away by very powerful winds.

Economic impact:

There is also an impact on the economic because the government need to repair the consequences caused by this natural phenomenon because people’s livelihoods are wiped away.

• How to prevent:

Follow the arrival of the hurricanes:

• with geostationary or polar satellite

• with aircraft specialize in the hurricane track

• with weather balloon which have a probe to take measure, to complete information from the others ways

Treat the information:

All this information is handled by specialists of hurricanes:

-strength

-airspeed

-longevity

-trajectory

 Thanks that, they prevent the trajectory, the strength, the air speed and his longevity of this hurricane.
