  2. Dew point - Wikipedia

    en.wikipedia.org/wiki/Dew_point

    The dew point temperature equals the air temperature when the air is saturated with water; in all other cases the dew point will be less than the air temperature. [ 6 ] : 129 In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same ...

  4. Wet-bulb temperature - Wikipedia

    en.wikipedia.org/wiki/Wet-bulb_temperature

    The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.

  5. Humidex - Wikipedia

    en.wikipedia.org/wiki/Humidex

    When the temperature is 30 °C (86 °F) and the dew point is 15 °C (59 °F), the humidex is 34. If the temperature remains 30 °C (86 °F) and the dew point rises to 25 °C (77 °F), the humidex rises to 42. The humidex is higher than the U.S. heat index at equal temperature and relative humidity. The humidex formula is as follows: [7] [8]

    The NWS office in Tulsa, Oklahoma, in conjunction with Oral Roberts University's mathematics department, published an approximation formula to the WBGT that takes into account cloud cover and wind speed; in limited experimentation (four samples), the office claimed the estimate was regularly accurate to within 0.5 °F (0.28 °C), even with a ...

  8. Convective available potential energy - Wikipedia

    en.wikipedia.org/wiki/Convective_available...

    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.

  9. Convective condensation level - Wikipedia

    en.wikipedia.org/wiki/Convective_condensation_level

    The CCL is determined by plotting the dew point (100%RH) versus altitude and locating the intersection with the actual measured temperature sounding. It marks where the cloud base begins when air is heated from below to the convective temperature , without mechanical lift.
