AEROGRAPHER'S MATE 3 & 2 air particles, the forces that are in balance with the pressure gradient when aloft are weakened when introduced to the frictional layer over the earth. This means that the pressure force is the dominating force at the surface, and the surface wind direction is pulled somewhat toward the direction of the pressure force. (See fig. 13-5.) Cyclostrophic Wind The Coriolis effect is at a minimum near the Equator; and as a result, the pressure gradient force is balanced primarily by the centrifugal effect. The wind that results when the pressure gradient force is balanced by the centrifugal effect is called the cyclostrophic wind. In the cyclostrophic wind, the pressure gradient force is inward-directed and the centrifugal effect is outward-directed. This is the balance of forces for a low-pressure system near the Equator. An example of cyclostrophic winds are the winds found in a hurricane. Convergence and Divergence Convergence is the condition that exists when the distribution of winds within a given area is such that there is a net horizontal inflow of air into an area. The removal of the resulting excess is accomplished by an upward move- ment of air; consequently, areas of convergent winds are regions favorable to the occurrence of precipitation. Divergence is the condition that exists when the distribution of winds within a given area is such that there is a net outward horizontal flow of air from the area. The resulting deficit is compensated by a downward movement of air from aloft; areas of divergent winds are regions unfavorable for the occurrence of precipitation. Since the wind flows from higher to lower pressure areas, it can be seen that convergence is associated with low-pressure areas and divergence with high-pressure areas. (See fig. 13-6.)
