HURRICANES AND

TORNADOES

Made by : Yahia Ahmed Salem 5b

Hurricanes

◦ (^) Hurricanes are powerful swirling storms found in the tropical parts of the Atlantic Ocean. The winds in a hurricane are very fast, over 120 kilometers an hour. Hurricanes around the Indian ocean and Oceania are tropical cyclones, while hurricanes in the Pacific Ocean are called typhoons.

Tornadoes

◦ (^) What is a tornado? Tornadoes are small, very powerful whirlwinds. They form suddenly into a rapidly twisting funnel of air and cloud stretches from the bottom of a thundercloud to the ground.

How do tornadoes form?

◦ (^) A tornado starts deep inside a thundercloud, when a column of rapidly rising storm warm air is set spinning by the strong winds blowing through the top of a cloud. Like a hurricane, a tornado is powered by rising humid air. However, a tornado is narrower, faster and more violent than a hurricane and it destroys everything in its path. Tornadoes often occur in small groups and, unlike hurricanes, are often found far inland, although a tornado travels across the land at speeds of 30 to 65 kilometers an hour, the wind speeds inside the tornado can reach 800 kilometers an hour. A tornado may measure anything from just a few meters to more than 100 meters across. It can travel for more than 200 kilometers before it uses up all it’s energy. Occasionally a tornado lasts for several hours, but most last for only a few minutes.
