heat exchange
Explanation:
The sun heats the earth's surface.
Heat from the surface rises because of the denser colder air above it. The strength of wind is dependent upon the co-efficient of hot and cold. For example, during the summer months a cold front will form and push eastward into warmer air. The great the differential between hot air and cold air, the stronger the winds that are produced.
Winds are also formed around the cyclonic action of air, that is the differential between high and low pressure areas. As air pressure drops the likelihood of a storm rises. When pressures drop to around 900 milibars you have large typhoons form in the Pacific and hurricanes in the Atlantic.
