Winds are more or less rapid horizontal displacements of air masses caused by differences in the pressure distribution. Due to the fact that pressure variations are mainly caused by temperature variations, it follows that the wind’s main motor is the divergence in solar radiation in the different regions of the world. Winds can be divided into ground level winds, that blow in the lower strata of the troposphere, and high altitude winds.
