In meteorology, an inversion (or temperature inversion) is a phenomenon in which a layer of warmer air overlies cooler air. Normally, air temperature gradually decreases as altitude increases, but this relationship is reversed in an inversion. [2] An inversion traps air pollution, such as smog, near the ground.
This means that the surface temperature is reduced from the effective mean radiating temperature by 16%, which is a potentially significant cooling effect. [1] This is an ideal case and represents the maximum impact the anti-greenhouse effect can have and will not be the impact for a real planet or large moon.
In many cases, the z-bottom value is the ground and the z-top value is the LFC. CIN is an energy per unit mass and the units of measurement are joules per kilogram (J/kg). CIN is expressed as a negative energy value. CIN values greater than 200 J/kg are sufficient to prevent convection in the atmosphere.
The red line is temperature, the green line is the dew point, and the black line is the air parcel lifted. In meteorology , convective available potential energy (commonly abbreviated as CAPE ), [ 1 ] is a measure of the capacity of the atmosphere to support upward air movement that can lead to cloud formation and storms.
The sink is actually a large fan housed in a chimney-like structure, and works by defeating surface temperature inversion. Cold air is denser than warm air, and will pool at ground level during calm weather. This lowers the surface temperature, even if the ambient temperature is higher. Vents near the base of the chimney allow cold surface air ...
Tropospheric ducting is a type of radio propagation that tends to happen during periods of stable, anticyclonic weather. In this propagation method, when the signal encounters a rise in temperature in the atmosphere instead of the normal decrease (known as a temperature inversion), the higher refractive index of the atmosphere there will cause the signal to be bent.

It varies with the temperature and pressure of the parcel and is often in the range 3.6 to 9.2 °C/km (2 to 5 °F/1000 ft), as obtained from the International Civil Aviation Organization (ICAO). The environmental lapse rate is the decrease in temperature of air with altitude for a specific time and place (see below). It can be highly variable ...
