  2. Inversion temperature - Wikipedia

    en.wikipedia.org/wiki/Inversion_temperature

    The inversion temperature in thermodynamics and cryogenics is the critical temperature below which a non-ideal gas (all gases in reality) that is expanding at constant enthalpy will experience a temperature decrease, and above which will experience a temperature increase.

  3. Thermocline - Wikipedia

    en.wikipedia.org/wiki/Thermocline

    Graph showing a tropical ocean thermocline (depth vs. temperature). Note the rapid change between 100 and 1000 meters. ... This is known as an inversion (a further ...

  4. Inversion (meteorology) - Wikipedia

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

    A temperature inversion in Bratislava, Slovakia, viewing the top of Nový Most (2005). Inversion-created smog in Nowa Ruda, Poland, 2017 Temperature inversion phenomenon in the early morning near Tawau, Sabah, Malaysia where smoke that was emitted from an oil palm mill stayed close to the ground. The wind carried the smoke in the direction of ...

  5. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    A gas must be below its inversion temperature to be liquefied by the Linde cycle. For this reason, simple Linde cycle liquefiers, starting from ambient temperature, cannot be used to liquefy helium, hydrogen, or neon. They must first be cooled to their inversion temperatures, which are -233 C (helium), -71 C (hydrogen), and -42 C (neon). [11]

  6. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. Within the stratosphere temperatures increase with altitude (see temperature inversion); the ...

  7. 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.

  8. Negative temperature - Wikipedia

    en.wikipedia.org/wiki/Negative_temperature

    If a negative-temperature system and a positive-temperature system come in contact, heat will flow from the negative- to the positive-temperature system. [ 1 ] [ 2 ] A standard example of such a system is population inversion in laser physics .

  9. Skew-T log-P diagram - Wikipedia

    en.wikipedia.org/wiki/Skew-T_log-P_diagram

    In practice, since temperature usually drops with altitude, the graphs are usually mostly vertical (see examples linked to below). The major use for skew-T log-P diagrams is the plotting of radiosonde soundings , which give a vertical profile of the temperature and dew point temperature throughout the troposphere and lower stratosphere .
