Answer:
Prevailing winds influence the precipitation by regulating amount of water vapor in air, direction of wind movement and by making cold and hot air masses to move.
Step-by-step explanation:
Winds make both hot and cold air masses to move. The hot air rises up with wind and cold air rushes to take its place. The hot air coming from water bodies towards the land carry ample of water vapor and causes precipitation in the region. On the other hand, the air coming from land masses does not have enough water vapor to cause any rains in the region.
