Document Summary
Temperature change with increasing altitude within the troposphere is relatively predictable. Environmental lapse rate: observed trend of vertical temperature change in the atmosphere. Lapse rate of a column of air involves measuring air temperature at various. If the air is moving vertically, expansion or compression will cause an adiabatic altitudes. temperature change. Most prominent exception to an average lapse rate condition temperature inversion - a situation in which temperature in the troposphere increases, rather than decreases, with increasing altitude; inversions influence weather and climate. Inversions also contribute significantly to increased air pollution because they create stagnant air conditions. Most readily recognizable inversions are those found at ground level radiation inversions can develop on a long, cold winter night when a land surface rapidly emits longwave radiation into a clear, calm sky. Rad inversions are primarily winter phenomena because there is only a short daylight period for incoming solar heating and a long night for radiational cooling.
