Question

What are the two types of downbursts, and how are they different? How is a funnel cloud different from a tornado? List the various stages in the formation of a tropical cyclone or hurricane, in order. Why does a hurricane begin to dissipate after it makes landfall? Explain how the heat index and the wind chill index are similar and different. What type of severe weather prevents sweat from evaporating to cool down bodies?

Answer 1

If a tornado causes considerable damage with wind speeds of 111 to 135 miles per hour, it’s classified as E2F tornado on the Enhanced Fujita Scale.

The type of major storm called a/an hurrican or tropical cyclone is driven primarily by the Coriolis effect.

The weather pattern that stays over one area for an extended period of time is known as recurrent weather.

Downbursts are classified into two types: macrobursts and microbursts. A macroburst affects an area larger than 2.5 miles in diameter. A microburst affects an area less than 2.5 miles in diameter.

A funnel cloud is formed when a spinning column of air descends from a thunderstorm. A funnel cloud, on the other hand, does not become a tornado until it makes contact with the ground.

Warm ocean waters generate tropical cyclones like hurricanes. When they reach land, they lose their fuel source and begin to deteriorate.

The heat index and the wind chill index are similar in that they both take into account various elements that influence how warm the air feels. The heat index takes relative humidity into account in proportion to air temperature. Higher humidity raises the perceived temperature of the air. The wind chill index takes wind speed into account in proportion to air temperature. Wind speeds increase the sensation of coldness in the air.

Heat waves—When combined with excessive humidity, heat waves can be extremely deadly. On hot days, the human body relies on perspiration evaporation to keep cool. The rate of evaporation reduces when humidity levels are high. As a result, it becomes more difficult for the body to cool itself and much easier for the body to overheat.

Answer 2

1. EF-2

2. hurricane/tropical cyclone

3. recurrent weather

4. The two types of downbursts are macrobursts and microbursts. A macroburst affects an area that's greater than 2.5 miles across. A microburst affects an area that's less than 2.5 miles across.

5. A funnel cloud forms as a spinning column of air that descends from a thundercloud. However, a funnel cloud doesn't become a tornado until it actually touches the ground. Once it touches the ground, where it begins to pick up dust and debris, it becomes a tornado.

6. Tropical cyclones, such as hurricanes, are fueled by warm ocean waters. Once they make landfall, they lose this fuel source and begin to lose strength.

7. The heat index and the wind chill index are similar because both consider other factors that affect how air temperature feels. The heat index considers relative humidity in relation to air temperature. Higher humidity makes air temperatures feel hotter. The wind chill index considers wind speed in relation to air temperature. Higher wind speeds make air temperatures feel colder.

8. Heat waves—Heat waves can be very dangerous when accompanied by high humidity. The human body depends on evaporation of sweat to cool itself down on hot days. When humidity levels are high, the rate of evaporation slows down. Consequently, it becomes harder for the body to cool itself and much easier for the body to overheat.
