As the wind increases the body is cooled at faster rate causing the skin temperature to drop Wind Chill does not impact inanimate objects like car radiators and posed water pipes because these objects cannot cool below the actual air temperature Wha 1 23 Chennai C C h The Indian wind is as diverse as the country itself, contributingto India’s distinct character. Above all, it’s the monsoon that shapes the life and culture of the people. Konstantin Vinnikov & Eric . Hohman. (Office of State Climatologist for Maryland).

Wind is created by differences in air pressure. Bigger difference = faster wind. Caused by unequal heating of earth. Air. The air by the equator is warm and rises. Low pressure. The air by the poles is cold and dense. Chapter 2.2 Guided Notes. What is Weather?. Weather is the condition of Earth’s atmosphere at a particular time and place.. What is Wind. ?.
