Eyes in the sky help us guess where and when it will rain

Eyes in the sky stay high in outer space and look down on earth. There are many of them; some remain fixed over the same spot on the world's surface, while others keep going round and round. They see most of what happens on earth, and we might like them or not. However, some eyes in the sky only see the air, the water and the clouds, so they are not to worry about. We can actually make good use of them. These special eyes in the sky make pictures using the light coming from or mirrored by the earth and passing through the air. With these pictures, people can tell how warm or cold the air is, how much water is in the air, where and when clouds form, and even how fast the wind blows. We can also pass this information on to big computers, which can use it to guess whether it will get warm or cold in the next few days, where the air will rise and form clouds, where it will rain. It seems big computers are learning to do this job completely on their own, with very little help from men. Anyway, they will always need pictures from the eyes in the sky. At work, I do nothing with the information coming from the eyes in the sky. Some friends have great fun with it, but I like it a lot more to understand how the air moves over or around mountains. I am mostly interested in how mountains help make rain (which is sometimes too much for us) and strong winds (which can blow things away or feed big fires), and also in how mountain winds move stuff around.
