  2. Inversion (meteorology) - Wikipedia

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

    Steep canyon walls act as a horizontal barrier, concentrating the smoke within the deepest parts of the canyon and increasing the strength of the inversion. [1] 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 ...

  3. Planetary boundary layer - Wikipedia

    en.wikipedia.org/wiki/Planetary_boundary_layer

    Atmospheric stability occurring at night with radiative cooling tends to vertically constrain turbulent eddies, thus increasing the wind gradient. [8] The magnitude of the wind gradient is largely influenced by the weather, principally atmospheric stability and the height of any convective boundary layer or capping inversion.

  4. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    Temperatures remain constant with height from the tropopause to an altitude of 20 km (12 mi), after which they start to increase with height. This is referred to as an inversion, and it is because of this inversion that the stratosphere is not turbulent. The stratosphere receives its warmth from the sun and the ozone layer which absorbs ...

  5. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    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 top of the stratosphere has a temperature of about 270 K (−3°C or 26.6°F). [9] [page needed]

  6. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    The troposphere is the lowest layer of the atmosphere of Earth. It contains 80% of the total mass of the planetary atmosphere and 99% of the total mass of water vapor and aerosols, and is where most weather phenomena occur. [1] From the planetary surface of the Earth, the average height of the troposphere is 18 km (11 mi; 59,000 ft) in the ...

  7. T wave - Wikipedia

    en.wikipedia.org/wiki/T_wave

    According to Sokolow-Lyon criterion, the height of R wave in V5 or V6 + the height of S wave in V1 more than 35 mm would be suggestive of left ventricular hypertrophy. [4] Both right and left bundle branch blocks are associated with similar ST and T wave changes as in hypertrophic cardiomyopathy, but are opposite to the direction of the QRS ...

  8. Capping inversion - Wikipedia

    en.wikipedia.org/wiki/Capping_inversion

    A capping inversion is an elevated inversion layer that caps a convective planetary boundary layer. The boundary layer is the part of the atmosphere which is closest to the ground. Normally, the sun heats the ground, which in turn heats the air just above it. Thermals form when this warm air rises into the cold air (warm air is less dense than ...

  9. Lapse rate - Wikipedia

    en.wikipedia.org/wiki/Lapse_rate

    The environmental lapse rate (ELR), is the actual rate of decrease of temperature with altitude in the atmosphere at a given time and location. [6]The ELR is the observed lapse rate, and is to be distinguished from the adiabatic lapse rate which is a theoretical construct.
