Cold currents definition
WebAir current. 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 ... WebThis is a map ocean surface currents from 1877. (John James Wild, 1877) At the surface, currents are mainly driven by four factors—wind, the Sun’s radiation, gravity, and Earth’s rotation. All of these factors are interconnected. The Sun’s radiation creates prevailing wind patterns, which push ocean water to bunch in hills and valleys.
