As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic, muscular tubes that carry blood to every part of the body.

Because it is a fluid system, the atmosphere is capable of supporting a wide spectrum of motions. These range from turbulent eddies of a few meters to circulations with dimensions of the Earth itself. By rearranging mass, air motion influences otheratmospheric components such as water vapor, ozone, and cloud, which figure prominently in radiative and chemical processes. Such influence makes the atmospheric circulation a key ingredient of the global energy budget.
