Hurricanes produce fierce winds.
Though fatalities were low in comparison to Hurricane Katrina, according to the National Hurricane Center, Hurricane Sandy resulted in “the greatest number of U.S.
This storm was given the name Hurricane Katrina.
What are hurricanes? A hurricane is a large, rotating storm with strong winds blowing at speeds of 74 miles an hour or more around a relatively calm center called the eye. Hurricanes blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The storm can be 5 to 6 miles high and 300 to 600 miles wide. It moves forward acting as an immense spinning top at speeds of 12 miles and hour. These storms are also called tropical cyclones in the northern part of the Indian Ocean in the Bay of Bengal and, typhoons in the western area of the North Pacific Ocean in Japan and Korea. They can dominate the atmosphere and the surface over thousands of square miles. They start in certain seasons in low latitudes in tropical oceans by the equator.
According to John Roach of National Geographic, these conditions have occurred very frequently since 1995 due to an increase in the temperature of the ocean, which created more vapor, heavy rainfall, and serious hurricanes....
However in late August 2005 a catastrophic hurricane struck.
The hurricanes move forward in a westerly direction parallel to the equator. Scientists now have the help of satellites, radar, and airplanes and keep close watch over the storms. The hurricanes are given names and are carefully tracked. Scientists gaining ground on understanding the many factors that create hurricanes, they have yet to determine the exact processes of formation. A hurricane must have the exact ingredients of warmth and water vapor to supply its energy. It also must have a certain amount of convection activity and vertical wind motion to bring air from the sea level to move through the storm system. The hurricane also needs the exact amount of twist that the earth gives.
Out of the blue, a hurricane rips apart your newly built house.
A hurricane must obtain its energy from something. Huge amounts of energy are created when warm water is evaporated from tropical seas. The hurricane stores this energy as latent heat in the water vapor which forms the clouds that circle the hurricane eye. 90 percent of this heat energy is released when the vapor expands. As the water vapor condenses into rain, 90 percent of the energy is released. As little as 3 percent is converted to mechanical energy, or energy of the circulating winds. The small amount of mechanical energy is equivalent to 360 billion kilowatt-hours per day. The total electrical energy the United States uses each day is only about 2 billion. The mechanical energy of a hurricane in a single day is equal to about a six-month supply of electrical energy for the United States.
In my country, Peru, hurricanes are not known.
The devastating effect of this hurricane resulted in more than 1,800 citizens losing their lives, as well as more than an estimated $81 billion dollars in damages occurred.
The Hurricane was a Category 4/5.
The structure of the hurricane also defines it. The chaotic and violent huuricane has a definite structure and a well-defined pattern of winds. Scientists probe closer into these storms and find more about them. A hurricane has an area of relative calm in the center that is called the eye. This is where the winds and clouds spiral in enormous bands. Around this eye, a bank of clouds blows, and this is the region of strongest winds. In the wall of clouds, the chimney or hot tower is located(Tufty, 18). This tower is the primary energy cell of a hurricane, where moist heated air moves upward from the ocean surface. As the winds spiral into the center of the storm, they bring in moist air in bands of precipitation called rainbands. They can be 50,000 feet high and extend outward from the storm’s center for hundreds of miles. At the edge of the whole rotating storm, 200 to 300 miles from the eye, winds blow in short flurried gusts.
