Atmospheric Circulations
Wind, or the motion of air with respect to the surface of the Earth, is fundamentally caused by variable solar heating of the Earth's atmosphere. This chapter presents a simplified version of model circulation to illustrate the role of the temperature distribution in the atmosphere in the production of winds. Atmospheric pressure is produced by the weight of the overlying air. Molecular conduction is achieved through the motion of individual molecules and is negligible in atmospheric processes. Eddy heat conduction involves the transfer of heat by actual movement of air in which heat is stored. The motion of an elementary air mass is determined by forces that include a vertical buoyancy force. Depending upon the temperature difference between the air mass and the ambient air, the buoyancy force acts upwards, downwards, or is zero. Large‐scale wind flow fields may be divided into two main types of storm: extratropical (synoptic) storms, and tropical cyclones.
