2: The hurricane is the most powerful tropical storm. Over 100 tropical storms form each year. Hurricanes form out in the ocean in warm tropical waters, usually in waters that are warmer than 80 degrees. A hurricane can form when groups of thunderstorms move through these warmer waters. The Earth's rotation causes winds in the storm to spin in a counterclockwise direction, and pick up speed. | What Causes a Hurricane?
3: The spinning winds become a hurricane when the winds reach a speed of 74 miles an hour. By that time, an "eye" has formed, which is the center of the storm. Surrounding the eye is the "Eyewall," a thick wall of clouds, heavy rains and forceful winds. The winds can get up to 200 miles an hour, pushing the storm inland. | This is the eye wall.
4: In 1953 meteorologists began naming the storms. Women's names were mainly used at first, then they added in men's names. One year, storms have female names, and the next year they are male names. Each storm is given a name from a list, in alphabetical order. If the storm is really devastating, the name will not be used again. Andrew and Camille are names which will not be used again. | How are Storms Named?
5: The winds of hurricanes
6: Katrina | Hurricane Katrina started on 8/25/06. Katrina was a category 1 by 4:00 p.m. The winds were at 80 MPH. It was near Miami. On Saturday 8/27 it was a category 3 storm. The winds were 115 MPH. Now it was more in New Orleans. There were 18,000 people trying to evacuate the area. On 8/28 the storm was a category 4. Few hours later it was a category 5. The winds were at 175 MPH. All citizens of New Orleans were asked to leave their homes. They had shelters set up.
8: Types of Destruction | In a hurricane, there are winds so strong that they can carry away forests. They can take off roofs to houses. Boats that were in the water can land on the shore. Birds can be blown away. Some house walls looked like they were breathing. Sometimes, there is major flooding with hurricanes. There are 5 categories of winds. 1 is weak, 2-4 is major and 5 is 175 mph and up.
9: These hurricanes are very dangerous. There are usually 6-12 inches of rain. There are usually surges which are rushes and where the ocean rises.
10: Do you want to know how they work? Well they work by the convection currents and the cool, dense air mixing with warm, moist air. The air begins to spin and pick up speed. This makes the eye of the hurricane. | This is what a hurricane looks like when you are in a boat ion the water. | RUNNNN!!! | Some More Facts About the Hurricane
11: They can cause major damage to the land and the people's lives that can not be replaced. | This is what happens when the hurricane storm surge hits land.
