How Do Hurricanes Form?

Hurricane is a big storm! They can spiral up and down up to 600 miles in length at speeds of 75 miles per hour and 200 miles per hour. All hurricanes last for more than a week and will travel at an altitude of 10 - 20 miles per hour in the open ocean.

It has warm air in its center and hurricane is different from the temperate cyclone which is the most common type of storm in the United States. The center of Arashi is the quietest part. It is called the eye, it is only breeze and fine weather. Low level storms rotate counterclockwise around the eyes of the northern hemisphere (clockwise in the Southern Hemisphere). Beyond 9 km, wind in the northern hemisphere turns outward and turns clockwise

Hurricane did important work for the earth. They help to transfer heat from the warm tropics to the cool, temperate areas. For this purpose they are usually formed between 5 and 15 degrees north and south of the equator. It is then destroyed by high waters in the warm ocean, such as the Atlantic Ocean, the Gulf of Mexico, the Caribbean, the Western Pacific (called Typhoon).

A hurricane occurred during the summer when the ocean warmed up. In the North Atlantic, the hurricane season lasts from June 1st to November 30th, but most hurricanes occur in the fall.

When a hurricane turns around the storm and around it they push water on the mound in the center of the storm. As the storm reaches the land, the mountain of water becomes dangerous as it causes flooding along the coast. Water accumulated and I could not escape anywhere, but I could not escape to land. In regions where the ocean floor is gradually inclined, even higher tide will occur by hurricanes.

When storm surges occur at storm surge, the two combinations are called storm surges. During the storm, the water level may be more than 20 feet higher than usual. This led to a flood. Storm surges are particularly dangerous for islands and coastal areas and even a few feet of surge can cause a major flood.

With computer model predictors can predict storm surges that affect coastal areas. The model called SLOSH calculates the number of storm tides that can be caused by hurricanes, considering the intensity of the storm, the path, the shallowness of the ocean, and the shape of the land.

How was the hurricane formed? Dust and sand in the eastern part of the Sahara blows to the Atlantic Ocean to the west. At the same time, small convection starts to be formed due to temperature difference. The moist air flowing from the sea level (at least 26 ° C) rises towards cooler air and falls to fill that position. Water vapor adheres to dust and sand and forms clouds. Convection accelerates, clouds become thunderstorms. Finally, due to the counterclockwise rotation of the Earth, the cloud starts to rotate. Depending on wind speed, the cyclone has various titles.

A hurricane is a big storm that winds rotate. If there is a large pressure difference and temperature difference between hot water and clouds, they form warm seawater. Clouds draw moisture and air near the surface of the water toward the clouds, creating a series of fast-moving air. Sometimes the air in one place is warmer than the air in another nearby. Warm air is thinner and lighter than cold air. When heavy cold air comes in contact with hot air, push it and push it. Some warm air moves sideways, some of which move up. As warm air moves laterally and continues to move upwards and outwards, cold air will flow and replace that position. The movement of this air is the wind. In most cases, most of the air on the surface of the earth is moving.
