Beside the big currents of the general atmospheric circulation like trade winds, there are periodical and regional winds like: mousoon, foehns, mistrals. Each of them influences the climate of the region in which it blows. Even if these winds are specific to a certain region, they obey those laws of the big currents: they move from the high pressure zones towards those with low pressure.
