Winds are identified by the direction from which the wind comes a west wind blows from west to east. Pressure Gradients Wind is caused by differences in atmospheric pressure from one place to another Air tends to move from regions of high pressure to regions of low pressure Isobars: lines on a map drawn through all points having the same atmospheric pressure Pressure gradient: change of atmospheric pressure measured along a line at right angles to the isobars The Coriolis Effect and Wind Coriolis Effect Apparent deflection of the wind N. hem: wind is deflected to the right S. hem: wind is deflected to the left....
