These climatological high pressure cells shift towards the poles in the summer and towards the equator in the winter, playing a major role in the formation of the world's subtropical and tropical deserts as well as the Mediterranean Basin's climate.
These climatological high pressure cells migrate by latitude according to the direct angle of the sun, shifting north-eastward in the summer and toward the equator in the winter. These semi-permanent high pressure systems play a major role in the formation of the world's subtropical and tropical deserts as well as the Mediterranean Basin's climate.
