Abstract
All parts of the atmosphere does not receive energy in a homogeneous manner. This difference leads to air motion following the principle that warm air is likely to reach high altitudes due to its low density compared to cool air. The difference in temperature and pressure is one of the key points responsible for atmospheric motion. In this study, we will try to give a simple and complete description of the principal causes of motion in our atmosphere and explain an impressive phenomenon linked to atmospheric instability, avoiding any annoying calculation, simply by referring to our logic.
The general dynamism of atmosphere refers to all the causes of air displacement in the atmosphere. These tendencies are under the influence of a force: the Coriolis Force which is responsible for curbing atmospheric trajectory. We should also deal with other factors on which atmospheric motion depends. The effect of gravity issues directly from the problem of air density, so it should be taken into account as well as the rotation of the earth characterized by the Coriolis force. Under these assumptions, one needs to set limits to the problem to comprehend it and to make it as much realistic as possible.
