How do air currents work
WebAir currents work because of differences in atmospheric pressure. Air always moves from areas of high pressure to areas of low pressure. This movement creates wind, which can … In meteorology, air currents are concentrated areas of winds. They are mainly due to differences in atmospheric pressure or temperature. They are divided into horizontal and vertical currents; both are present at mesoscale while horizontal ones dominate at synoptic scale. Air currents are not only found in the troposphere, but extend to the stratosphere and mesosphere.
