The biggest storm on Earth

The wind appears in the current lot. A few months ago there was the wind in the form of tornadoes, soon it will factor temperature. Today, hurricanes, but there's more wind in these storms.

The Cyclones (Hurricane Taino word for "bad spirit"), are technically tropical cyclones. In the Caribbean, called the God of all evil, and those were to punish the wrath of the gods. Regardless of how the hurricanes are called, they are the largest thunderstorm on Earth.

The birthplace is the hurricanes in the tropics. Capture the latitude 5 to 20 degrees north or south of the equator, in areas where the ocean, the temperature reached 80 in summer and autumn.

Hurricanes begin, as an air mass is unstable and often, when the field of convergence, by the winds of the two hemispheres is the reduction of more than unusually warm zones of the sea There must be far enough from the equator to the strengths of the rotation due to the winds Spiral, as defined in the northern hemisphere, and right in the southern hemisphere.

The hurricane draws its energy from the ocean, with energy in the form of heat transfer the water into the air. A large amount of water vapor evaporates and transported to the top by strong winds spiral. Clouds increase if the latent heat is the moment where the steam condenses in the clouds. Since warm air and moisture increased, a zone of low pressure is created near the surface. This attracts more air and moisture, and the system grows. This process will continue until the system from 90 to 400 miles across.

When the wind speed reached 39 miles per hour, the storm is a tropical storm and the storm is a name. The old tradition, the names of the storms of women was abandoned in 1979, now they receive both the male and female names.

In one of the 10 tropical storms, the wind speed is 74 miles per hour, these storms will be updated hurricane. The hurricanes can develop to 300 miles or more in diameter, and from 10 to 50 miles per hour. The wind speed in storms that can store up to 200 miles per hour.

One of the things Oddest to the hurricanes is the eye of the storm. In the center of the storm system is a zone of 25 miles through the remarkably quiet and calm. The hurricane survivors to speak, as it is strange and shows the eye of the storm: the blue sky above surrounded by a wall of clouds in anger. Ships at sea known to survive hurricanes by the electoral district in the eye of the storm.

The winds of hurricane damage much, but that can minors in relation to the waves, the coastal areas to attack. The hurricane itself is a low pressure, but the eye in the middle is a high pressure. This strong, and the intense low pressure that surrounds them, creates a yearning to the centre, which is literally a wall of water up to 10 feet high. This wall of water is pressed, come in the hurricane and can take up to 25 feet high and the waves are by the wind. If these waves are embedded in the region of the bay, the effect of the compression of the mass of the surrounding areas can cause the waves rise up to 40 feet. It is already a bad situation even worse, if it with a flood.

More deaths were between the hurricanes, volcanoes and earthquakes. One of the worst hurricanes in history took place in 1970, Bangladesh and the killing 500000 people. In our country, we’ve more happy was the worst hurricane in the history of the U.S. 1900 was a storm, killing 6000 in Galveston, Texas.

A hurricane takes about ten days. Well, that is usually a way to west across the South Atlantic and then the arc to the north, near our coast; hurricanes follow a path very striking. A hurricane can change its flight path, when suddenly it is difficult to predict where it goes out.

Irony of fate, there is a useful page to the hurricanes. These systems are used to tropical storm to spread the heat of the tropics, sometimes the rainfall in the areas that otherwise would be dry. But it seems a small advantage if you look at the figures of mortality.

Thank you from meteorological satellites, we are capable of hurricanes better than ever before, and although we May not be able to accurately predict the ways we are at least warned.
