Horizontal distribution of air pressure??? Write notes |
|
Answer» The horizontal distribution of air pressure across the latitudes is characterized by HIGH or low pressure belts. The Equatorial Low-Pressure Belt: The sun shines almost VERTICALLY on the equator throughout the year. As a result, the air gets warm and rises over the equatorial region and produce equatorial low pressure.Explanation:Horizontal distribution of air-pressure on the earth’s surface is shown by means of isobars. Isobars are lines drawn through points of equal pressure. They are drawn at pressure intervals of 3, 4, or 5 millibars.Factors which control the distribution of temperature on the earth’s surface equally govern the distribution of pressure as well. This is mainly due to the fact that there is a close relationship between pressure and temperature.Since there is a great variation in the amount of INSOLATION received at different parts of the earth’s surface, there is a CORRESPONDING variation in temperatures also. |
