1 There are some ways of understanding the weather.
2 To study the clouds is one of them.
3 No two clouds in the sky are the same, but it is still possible to group clouds and to give them names.
4 You can learn to recognize the different kinds of clouds and watch how they move across the sky.
5 As a rule, as the clouds are higher, the weather is better, and as the clouds are lower, the weather is worse.
6 To predict the weather, you should look for three characteristics of clouds: movement, color, and change.
7 Clouds can tell you that a storm is on the way.
8 For example, cirrus clouds are high, thin, and airy.
9 If they become thick and move lower, this means rain is on the way.
10 Cumulus clouds are puffy clouds that look like balls of cotton.
11 If they get bigger early in the day, then you know it will rain.
12 If there’s a sudden cool breeze and a dark thunderclouds appears, then a storm is going to break out.
13 Clouds are not only signs of storms and rain.
14 They may also be signs of good weather.
15 Cirrus clouds may stay high in the sky and move very slowly.
16 This means it’s going to be fine weather.
17 Clouds are a sign of changing weather.
18 They can tell many things to you.
19 If you know a little more about them, you’ll become weather-wise.
