What is a hurricane?How does it differ from the storm, typhoon, strong winds, tornadoes or tornado?Why do hurricanes have such a destructive force?Is it possible to predict the birth of a hurricane, to avoid a collision with him?Try to understand.
What is a hurricane?
Hurricane - this is a very strong wind speed exceeding 120 kilometers per hour.If it reaches 180 kilometers, the hurricane is considered very strong.It can be rain and not having any relation to the tropics.The first image, as the name implies, over the tropics.Tropical cyclones originating over the Pacific Ocean, often called typhoons.They were accompanied by a low pressure area.Hurricanes, appearing over the Atlantic, often simply called cyclones.Non-tropical storms can occur in other parts of the planet, but the reason for their appearance is the same: the difference in temperature and atmospheric pressure in various atmospheric layers.The most dangerous are the hurricanes that form off the coast.They are rushing at breakneck speed, able to sweep out of the way the whole city.What is a hurricane?This is a terrible danger, to prevent that person has not yet learned.It is hundreds of dead, destroyed economy, destroyed the city.
Hurricane "Katrina"
It happened in August 2005 and remains one of the most destructive.He began to take shape in the Bahamas, and the next day reached such force that got fifth, the highest category, has not yet reached America.This means that the wind speed exceeds 280 kilometers per hour.At this rate, the earth may move, not all technical devices.Reaching the US, "Katrina" swept New Orleans in 1836 destroyed the Americans.More than 700 of them in New Orleans.In the area of the hurricane appeared just 4 staff.They declared emergency, the population was evacuated, but were unable to prevent the destruction, people still do not have such skills.Damage that "Katrina" struck the United States totaled $ 125 billion. What is a hurricane?This is, as the experience of New Orleans, rampant crime.After the city was moved freely marauders who looted shops and miraculously survived the building.It was reported several attacks on the city hospital.Truly a hurricane - terrible ordeal for people.
As a hurricane formed?
Photo above shows how the faces warm air and cold supply.If the water temperature in the tropics than 27 degrees, the likelihood is increased repeatedly hurricane.Facing each other, the air masses of different temperatures form a low-pressure area, which becomes the point of birth of the hurricane.At the speed of its development and movement can have an impact, and the Earth's rotation.Observing from space weather, scientists have learned to predict where there is the threat of a hurricane.But neither his strength, nor the exact path of movement it is unable to calculate.Well, if the government time to evacuate the places that can be destroyed by uncontrolled elements.And if not?
