WINDS
Posted On Friday, May 28, 2010 at at 7:03 PM by JoanThe tern WIND is commonly defined as air in motion. As mentioned earlier, winds originate whenever there is uneven distribution of tempeture and pressure in the atmosphere. When two adjoining masses of air differ in temperature, the warmer mass, being less dense, rises thus causing a decrease in pressure. The cooler and denser mass of air flows toward the low pressure area and replaces the rising air.
