Atmospheric Pressure And Wind Belts

Air pressure can be defined as total weight of a mass of column of air above per unit area at sea level. Pressure on one sq. cm area of the surface of earth would be equal to the actual weight of the column of air above that area extending upwards to the outer limits of the atmosphere.

• As air is compressible, so the air which lies in the lowest portion is greatly compressed and is therefore the densest whereas, as we move up, both density and pressure of the air decreases.
• As one goes up from sea level to higher altitudes, air ....
