Study of vortex state of the atmosphere

Abstract

The earth's atmosphere as a whole has a very complex system of movements, changing over time. The main features of these movements from year to year are repeated and are well represented on medium and climate maps, which are the source for conclusions about the General circulation of the atmosphere. So we know that the motion of the atmosphere has a vortex character. There are fundamental States of the three-dimensional vortex motion in which the convergence of the low pressure leads to rising motion and divergence high pressure leads to a downstream movement in a vortex (tornado). These states of the field of three-dimensional velocity can be described by a decomposition of the rate of convection through the current function and potential, which describe the spiral structure of this movement. In this work, we introduced a simple differential equation in partial derivatives, satisfying the basic condition of three-dimensional vortex motion. Also it is shown that when the swirling movement of the degenerates in the geostrophic wind, and the corresponding state of the vortex motion is replaced by the geostrophic condition.
