The Sun's heat causes air masses to form and circulate in the atmosphere. This movement creates differences in air pressure, which in turn, creates winds. Air moves horizontally because of differences in pressure. When air is heated, the air expands, the density decreases, and the air rises. When air is cooled, the air becomes more dense and sinks.
