Temperature nversion Temperature inversion nothing but a reversal of the normal behaviour of temperature in the troposphere, which is the region of the atmosphere nearest the Earth's surface.
Inversions play an important role in determining cloud forms, precipitation and visibility.
Heat in the form of long wave radiation escapes into space at night Cold air drains into the valley at night Light winds under high pressure allow valleys to cool much more than higher terrain. Since an inversion will usually control the upper level to which heat is carried by convection, only a shallow layer of air will be heated if the inversion is low and large, and the rise in temperature will be great.
A ground inversion develops when air is cooled by contact with a colder surface until it becomes cooler than the overlying atmosphere
Smooth air A subsidence inversion develops when a widespread layer of air descends. The layer is compressed and heated by the resulting increase in atmospheric pressure, and as a result the lapse rate of temperature is reduced. Stratocumulus Leve Turbulent air
A subsidence inversion develops when a widespread layer of air descends. Thee layer is compressed and heated by the resulting increase in atmospheric pressure, and as a result the lapse rate of temperature is reduced. Cooler Air Above Inversion Air Heated as it is Warmer Air compressed into the side of the hill Trapped Cooler Air
Frontal Inversion Warm air stops rising when it encounters the warmer air above A frontal inversion occurs when a cold air mass undercuts a warm air mass and lifts it aloft; the front between the two air masses then has warm air above and cold air below Warm Air Cold Air
