-1 What is a pressure gradient? A pressure gradient is a quantity that shows which direction and what rate pressure changes most rapidly around a certain area.(pressure gradient) Pressure gradient is expressed by units of pressure per unit of length. Difference in earth’s pressure is the cause of wind on earths surface and the direction in which the air flows. The Coriolis effect also effects wind direction, deflecting wind in the Northern Hemisphere to the right and deflecting wind in the Southern Hemisphere to the left.(Thompson 483) Without the Coriolis effect wind would flow directly across the isobars. Pressure gradient is the cause of wind speed by the magnitude of the pressure difference over a certain distance.(Thompson 481) Pressure gradients are measured by the closeness of isobars. High and low pressure zones move, changing the pressure gradients often. One of the causes of which direction the air flows is by pressure gradient force. Air must flow inward toward the low pressure region to replace the rising air mass.(Thompson 481) The
