A big storm is approaching some areas in Japan. More than 200,000 people have been told to leave their homes and go to after areas because of this storm – which is actually a typhoon.
The name of this is Typhoon Haishen and it is expected to become really strong today in Japan – bringing heavy rain and winds of more than 16 km per hour. It will reach South Korea on Monday (South Korea is near Japan).
Schools, offices and factories have been shut and flights have been cancelled because of this typhoon.
What is a typhoon? What’s the difference between hurricanes, cyclones and typhoons?
A typhoon is a tropical storm that develops the Northwest Pacific Ocean.
Typhoons, cyclones, and hurricanes, cyclones are all types of tropical storms. The tropics are the areas surrounding the Equator – the equator is a an imaginary line around the middle of our planet, which is halfway between the North Pole and the South Pole. The equator divides our Earth into a Northern Hemisphere and a Southern Hemisphere.
The difference between the three kinds of storms is only in the area where they take place.
- Hurricanes form over the North Atlantic Ocean and Northeast Pacific.
- Cyclones form over the South Pacific and Indian Ocean.
- Typhoons form over the Northwest Pacific Ocean.
What happens in a tropical storm?
In this kind of storm, the air rises quickly once it is heated by the warm sea water. Then, as the air cools down, it is pushed by more warm air rising from under it. This cycle causes very strong winds. When these storms happen over the sea, huge waves form, and when these waves reach the land area, they usually cause flooding in cities.
