The ocean, which occupies two-thirds of our planet, and the atmosphere enveloping it play a huge role in the life of mankind. Together forming the shell of the Earth, they function as a single mechanical and thermodynamic system. The joint study of these spheres and their interaction is the main direction of modern world hydrometeorological science. The book offered to the reader's attention is also devoted to these issues. It also shows that knowledge of the processes that occur in the ocean and atmosphere is of great practical importance, primarily for navigation, exploitation of ocean resources, for marine and meteorological forecasts. For readers interested in environmental issues.
