    When the air pressure of one area is greater than the air pressure of another area, the air rushes from the first place to the second. You can imagine if we have a hot desert, hot surface will heat the air directly above it; that warm air will rise. If there is a nearby ocean, which is cooler than the desert, the air above the ocean will be cooler and more dense. That cool air will push toward the area where the air is rising. This in particular is what causes sea breezes, but in general differental pressure is what drives local winds.

    The great wind fields of the earth are dominated by similar mechanisms with the earth’s rotation playing a larger role.
