There are lots of natural disasters every year. (1)

Typhoons are some of the worst storms, usually around the Pacific Ocean and the South China Sea. Most happen in July, August and September.
How does a typhoon happen? When lots of seawater gets hot in the summer sun, it evaporates(蒸发) into the air. This makes the air hotter. (2)

Then cooler air around it rushes in. It fills the space that is left. After the air gets warmer, it starts to move quickly, making wind. The wind goes in circles and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when wind moves faster than 30 metres a second, a typhoon begins.
A typhoon has two parts. One is called the “eye”. (3)

The other part is the wall of clouds around the eye. Here are the strongest winds and heaviest rain.
Typhoons are very dangerous. In November, 2013, Typhoon Haiyan killed 6,000 people in the Philippines. (4)
