The Hurricanes are responsible...

The Hurricanes are responsible for the delivery in enormous resources, the three East: wind, water and waves. The wind is often referred to as the destructive element in a hurricane, even though the vast majority of the damage and destruction are used in conjunction with water and waves. But the wind is not without its problems.

As the wind in the intensity of hurricanes, the system seems not to a threshold important. Damage is very widespread. Given the strength of the wind increases with the square of the speed, a doubling of wind speed leads to an increase of four of the possible damage. But beyond the normal hurricane winds, these storms often cause tornadoes. Even after a storm weakens and moves inland, with winds, tornadoes may continue during the hours, even days. The tornadoes are not very big, but the Midwest selection, but they are strong enough to tear roofs and uprooting trees. Normally, the formation of tornadoes in the front of the right quadrant of a hurricane. If the storm in the north, tornadoes formed in the northern area. In general, this sector most winds.

When a hurricane moves north, that the road to the north connects to the air in the north along the storm to strengthen the power of the wind. On the western side of the road to the north opposes the flow of air in the south, so that the power of the wind is weaker. The figure below shows how the storm track is the wind. In New England, one of the main concerns is to a hurricane in the west of the coast of the parties in the region and the movement on land to a fast speed. This combination is exactly what during the great hurricane of 1938, when 600 people were killed.

Either drag your ship from the water before the storm or bound. Are you concerned about the broken window panes, the use of plywood, as streaks. Make sure that you have a supply of batteries, canned food and drinking water.

Like the tornadoes, all doors and windows must be closed during the hurricanes. Because every construction is waterproof in the air, the differences between the pressure from inside and outside to build enough to cause explosions. An open window serve as input for scrap and water. The air may cause indeed a roof without further delay.

The torrential rains and accompanying hurricanes, as the wind, long after the storm is in the country. Some of the storms have delivered flash floods. For the United States, within the floods has been for more than 70 percent of the loss of human life hurricanes and tropical storms. For example, the tropical storm Claudette in 1979, has 45-inch rain in Alvin, Texas. Damage has hundreds of millions of U.S. dollars. Hurricanes Connie and Diane team that approximately 20-inch rain in New England in August 1955. The floods have one of the largest natural disasters in the region known to damage of 4.2 billion U.S. dollars, for 1990 U.S. dollars. Two hundred people were killed. Then the Hurricane Agnes in 1972, which remain on land and the day as a weakened, but a soaking-wet tropical storm. In U.S. dollars adjusted to the loss came to 6.4 billion U.S. dollars. The number of deaths on the 122nd In June 2001, the tropical storm Allison to a weakening of the depression, if he were in the area of Houston, but he has 30 to 40 inch rain. More than 40 people dead and 5.0 billion dollars damage has occurred while the storm slowly moved from Texas to Florida and north in Virginia. In 1998, Hurricane Mitch is the deadliest storms have hit the Atlantic basin since 1780. The torrential rains trigger landslides in Nicaragua, Honduras and El Salvador. At least 9,000 people were killed. The only other hurricane has cost more lives in the Atlantic basin was a storm, proposed by Barbados in Martinique in October 1780. This storm claims 22,000 lives.

The massive rainfalls from these storms, because the storms have a very large mass of moisture and are very unstable. If the floor is uneven, with many hills, the air is pushed upward, and the pressure in the atmosphere. Most regions inner fear that the rainy season of hurricanes far more than the wind.

There is also the waves and waves of water, which is on the shoreline. The strong winds collect the water along the coastal areas, as in the wind. This creates a wave, measuring 10 to 20 feet above the normal level of the tides. In addition, waves of 20 or even 30 feet combined with the increase. The low pressure in the center of the storm pulls the water even higher than if it was called by a straw. If the storm comes during a flood, normal, the situation is even worse. The Galveston hurricane of 1900 cost the lives of up to 6000 people, most of the strong tides. A large part of the damage from Hurricane Camille in 1969 was combined with a 25-foot storm tide when the storm moved into the coastal areas of Mississippi.
