Abstract

General circulation refers to the global motion of the atmosphere. This atmospheric motion is driven by the uneven surface distribution of net solar incoming radiation, with a surplus in the tropics and a deficit in the polar regions which is translated into larger outgoing long-wave radiation (OLR) than the one that is absorbed (Fig. 2.1). To compensate this imbalance, atmospheric and oceanic transport processes distribute the energy around the globe. Atmospheric winds and ocean currents accomplish this transport. From a dynamical point of view, the oceans and the atmosphere must be considered together as components of the climate system.
