  2. Inversion (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Inversion_(meteorology)

    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.

  3. Capping inversion - Wikipedia

    en.wikipedia.org/wiki/Capping_inversion

    A capping inversion occurs when there is a boundary layer with a normal temperature profile (warm air rising into cooler air) and the layer above that is an inversion layer (cooler air below warm air). Cloud formation from the lower layer is "capped" by the inversion layer.

  4. Marine layer - Wikipedia

    en.wikipedia.org/wiki/Marine_layer

    A marine layer is an air mass that develops over the surface of a large body of water, such as an ocean or large lake, in the presence of a temperature inversion. The inversion itself is usually initiated by the cooling effect caused when cold water on the surface of the ocean interacts with a comparatively warm air mass.

  5. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    As such, because the tropopause is an inversion layer in which air-temperature increases with altitude, the temperature of the tropopause remains constant. [2] The layer has the largest concentration of nitrogen. The atmosphere of the Earth is in five layers: (i) the exosphere at 600+ km; (ii) the thermosphere at 600 km;

  6. Tule fog - Wikipedia

    en.wikipedia.org/wiki/Tule_fog

    Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.

  7. Lake stratification - Wikipedia

    en.wikipedia.org/wiki/Lake_stratification

    Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.

  8. Tropospheric propagation - Wikipedia

    en.wikipedia.org/wiki/Tropospheric_propagation

    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.

  9. Inversion layer - Wikipedia

    en.wikipedia.org/wiki/Inversion_layer

    Inversion layer may refer to one of the following: Inversion (meteorology) , a layer within which an atmospheric property is inverted, i.e., its change is deviated from the normal pattern Inversion layer (semiconductors) , a layer in a semiconductor material where the type of the majority carriers changes to its opposite under certain conditions
