Encyclopedia > Surface temperature inversion

Surface Temperature Inversion is a phenomena that describes the difference in ambient temperature as the distance to an object's surface varies.


It is a specific type of Temperature inversion. A temperature inversion is a meteorological phenomenon where air temperature increases with height. ...


The definition usually applies to the observed meterological condition where the air temperature at ground level is cooler then the temperature above it. The phenomena usually occurs at night, when the ground cools quickly, cooling the air directly in contact with it. As air is a poor conductor of heat, the air closer to the surface cools more quckly, while air further above remains warmer.


Favourable conditions for surface temperature inversion are winter nights, where the night is longer, and the ground has more time to cool, calm weather, and clear skies. Topographical features such as dells and valleys may also contribute to pooling of cold air, and temperature inversions.


You may have noticed the effect of temperature inversion, when riding a bicycle on a cool winter's night (about 10°C - colder and your skin would find it hard to deferentiate the inversion). If you pay attention, you may experience warm and cool pockets of air -- caused by surface temperature inversion.

Frost - Wikipedia, the free encyclopedia (462 words)
It is also affected by differences in absorptivity and specific heat of the ground which in the absence of wind greatly influences the temperature attained by the superincumbent air.
The formation of white frost on the indoor surface of window panes indicates low relative humidity of the indoor air, otherwise water would first condense in small droplets and then freeze into clear ice.
In the absence of a site nucleating the formation of ice crystals, the leaves remain in a supercooled liquid state, safely reaching temperatures of -4 °C to -12 °C. However, once frost forms, the leaf cells may be damaged by sharp ice crystals.
