Question

Quizplus · Accepted Answer

The general circulation of the atmosphere consists of large-scale horizontal movements of air, such as the trade winds, westerlies, and polar easterlies. While there are some vertical movements involved (such as rising warm air at the equator and sinking cool air at the poles), they are not the primary characteristic of the general circulation. Adiabatic processes and jet streams are also present but do not make up the majority of the broad-scale air-movements.
