Question

Anyone who has experienced a cyclone (飓风) will tell you how terrible it can be. Highs winds and lots of rain can destroy a city in less then an hour.

A big cyclone, named Cyclone Debbie, hit Australia’s east coast at the end of March. Winds as fast as 263km/h destroyed houses, trees, cars and boats. Sea levels rose and flooded coastal towns, while rivers also flooded. Many cities near rivers went underwater. Hundreds of thousands of people had to leave their homes and farms, and at least eight people died. The cyclone lasted for about three days, but the flooding is still happening two weeks later. Some cities never recover from a cyclone, while it takes others years to rebuild.

A tropical cyclone (热带气旋) begins when a group of thunderstorms meet over warm, tropical waters. Lots of air and water is sucked into the clouds from the ocean. Because Earth is rotating(旋转), the clouds start to spiral(盘旋上升). That is why the tropical cyclone has a curved(弯曲的) shape when you see it on a map. For this reason, tropical cyclones cannot form near the Equator(赤道) because Earth’s rotation isn’t big enough there. When the wind speed increases to 120 km/h, it changes from a tropical cyclone to a hurricane, typhoon(台风)or cyclone.

So what’s the difference between a cyclone, a hurricane, and a typhoon? The answer is actually quite simple.

All three are the same. We just use different names for these storms in different places. In the Atlantic and Northeast Pacific Oceans around the US, it is called hurricane. The same type of storm in the North Pacific near China is called a typhoon and cyclones form in the South Pacific and Indian Ocean near Australia.
