WEATHER HAZARDS Global atmospheric circulation helps to determine patterns of weather and climate General atmospheric circulation model: pressure belts and surface winds Air circulates between high and low pressure belts as surface winds: Winds are large scale movements of air caused by differences in air pressure. Differences in air pressure are caused by differences in temperature between the equator and the poles. Winds move FROM the areas of high pressure TO the areas of low pressure. are part of global atmospheric circulation loops (or cells). These loops have warm rising air which creates low pressure belt. There are loops in each hemisphere and it works as below:
