7 Storms and Hurricanes

Storms and Hurricanes

风暴和飓风

Stormy skies. During a storm, there are thick, dark clouds in the sky, very strong winds and often heavy rain or snow. Sometimes, there is thunder and lightning, too. This is a big storm in Nebraska, U.S.A.

暴风雨的天空。在暴风雨期间，天空中有厚厚的乌云，强风，经常是大雨或大雪。 有时，也有雷声和闪电。 这是美国内布拉斯加州的一场大风暴

Different weather. Storms and other kinds of weather happen all over the world. Weather is formed in the air that surrounds the Earth. You can see weather from space. This picture shows white, swirling clouds. The gaps between the clouds are clear skies.

不同的天气。风暴和其他天气在世界各地都会发生。 天气是在环绕地球的空气中形成的。 你可以从太空看到天气。 这张照片显示的是白色的漩涡云。 云层之间的空隙是晴朗的天空。

The type of weather depends on how hot, cold, dry or damp the air is. Where the air is hot and dry, the weather is sunny and there's no rain. Cold and damp air makes cloudy, foggy, rainy or snowy weather. Many storms happen where the air becomes hot and damp. Other planets such as Jupiter have storms, too.

天气的类型取决于空气的热、冷、干或湿。 在空气炎热干燥的地方，天气晴朗，没有雨。 寒冷潮湿的空气造成多云、有雾、下雨或下雪的天气。 许多风暴发生在空气变得湿热的地方。 木星等其他行星也有风暴。

Cloudy skies. Storm clouds form when the air is warm and damp. Damp air is filled with very tiny water droplets, so small you can't see them. 1. The Sun shines and heats up the air making the water droplets rise. High above the ground, the droplets cool and join together to make clouds. Inside the cloud, the droplets bump together and join to form bigger droplets. Soon, the droplets of water are so big and heavy that they fall as rain.

多云的天空。当空气温暖潮湿时，就会形成风暴云。 潮湿的空气中充满了非常微小的水滴，小到你看不见它们。 1. 太阳照射并加热空气，使水滴上升。 在地面高处，水滴冷却并聚集在一起形成云。 在云内部，液滴碰撞在一起并结合形成更大的液滴。 很快，水滴变得又大又重，就像雨一样落下。

In some parts of the world, so much rain falls at once, the ground floods. This is Calcutta in India. It rains like this for around two months every year. In some parts of Hawaii, U.S.A., it rains almost every day.

在世界上的一些地方，一次下这么多雨，地面就被洪水淹没了。 这是印度的加尔各答。 每年大约有两个月像这样下雨。 在美国夏威夷的一些地区，几乎每天都下雨。
