PPT-Deserts Adiabatic Warming and Cooling

Deserts Adiabatic Warming and Cooling Warm moist air masses forced up and over mountains experience decreasing atmospheric pressure and as a result expand This process causes the expanding air mass to release a portion of its latent heat resulting in a decrease in air temperature This is called adiabatic cooling Depending on the height to which the air is forced the air mass temperature may drop below the dew point resulting in the formation of water droplets and precipitation in the form of rain or snow As a result when the air mass reaches the summit it is cold and dry Crossing the summit the air mass descends and compresses This produces a corresponding increase in atmospheric pressure and as descent continues the compressing air mass begin to warm This is a called adiabatic warming However because the moisture was released during the cooling stage the descending air mass is warm and dry If sufficient moisture is removed the descending air mass could be dry enough to create a rain shadow effect where precipitation is much lower than surrounding areas In some cases a rain shadow desert can form.

This process causes the expanding air mass to release a portion of its latent heat, resulting in a decrease in air temperature. This is called adiabatic cooling. Depending on the height to which the air is forced the air mass temperature may drop below the dew point, resulting in the formation of water droplets and precipitation in the form of rain or snow. As a result, when the air mass reaches the summit, it is cold and dry. Crossing the summit, the air mass descends and compresses. This produces a corresponding increase in atmospheric pressure and, as descent continues, the compressing air mass begin to warm. This is a called adiabatic warming. However, because the moisture was released during the cooling stage, the descending air mass is warm and dry. If sufficient moisture is removed the descending air mass could be dry enough to create a rain shadow effect where precipitation is much lower than surrounding areas. In some cases a rain shadow desert can form. Stephanie Evan; . LACy. /. CNRS. Karen Rosenlof; NOAA . ESRL . CSD. Troy Thornberry. ;. CIRES, . University of . Colorado & NOAA ESRL CSD.
