What affects the weather on your favorite outdoor spot? Why does the ocean act like this and not otherwise? Where does the Northern Lights come from?
In Windy.app Meteorological Textbook (WMT), of which I’m an editor and author, we are explaining in simple words the processes in the atmosphere, the ocean, and the earth. To keep an eye on the weather is even more interesting with Windy.app!

Outdoor writer from the Dolomites, Italy, and Karelia, Finland
— The idea of the textbook is to explain to you the basic, most interesting, and just bright meteorological and physical terms and phenomena in a simple language. So simple that no one else does so except Windy.app. So you read about the particular terms, understand everything and you have no questions. And you can retell it to others.

The book consists of five parts or sphere of the Earth:
- Atmosphere (Air)
- Hydrosphere (Water)
- Lithosphere (Land)
- Magnetosphere (Magnetism)
- Biosphere (Life)
Plus the Outer space (Cosmos).
There are more than 50 lessons in the book to this day.
