WebOct 11, 2024 · At this temperature, water releases about 585 cal/g as it condenses. Given the slope of its vapor pressure curve, about 1.1 torr/deg at 20°C, condensation will roughly triple the heat capacity of saturated air, reducing $\gamma$ and the lapse rate until the air has dried out. The effect is even greater in tropical climes, where the altitude of ... WebThis is how we get high and low pressure systems. The rate at which air pressure changes with height is determined primarily by the average temperature in the column under consideration. In colder regions, atmospheric pressure decreases more rapidly with height than normal or than is observed in warmer areas. Changes in Air Temperature with Height WebSince air is a gas, it responds to changes in temperature, elevation, and latitude (owing to a non-spherical Earth). Air pressure decreases naturally as we rise in the atmosphere, or up a mountain, we must make correction to the air pressure owing to elevation above sea level. These corrections are easily made by adding the the air can rats climb bird feeder poles
