    Wind vane (also called a weather vane or a weathercock) for showing the wind direction; Present Weather/Precipitation Identification Sensor for identifying falling precipitation; Disdrometer for measuring drop size distribution; Transmissometer for measuring visibility; Ceilometer for measuring cloud ceiling

  3. AccuWeather - Wikipedia

    en.wikipedia.org/wiki/AccuWeather

    AccuWeather has been granted a United States patent on The RealFeel Temperature, [23] but the formula is a trade secret and has not been reviewed by other meteorological authorities. In response to AccuWeather's "RealFeel", The Weather Channel introduced their "FeelsLike" temperature reading.

  4. Balance point temperature - Wikipedia

    en.wikipedia.org/wiki/Balance_point_temperature

    The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.

    en.wikipedia.org/wiki/Weather_station

    Weather station at Mildura Airport, Victoria, Australia.. A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate.

  6. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    The variation in temperature that occurs from the highs of the day to the cool of nights is called diurnal temperature variation. Temperature ranges can also be based on periods of a month or a year. The size of ground-level atmospheric temperature ranges depends on several factors, such as: Average air temperature; Average humidity

  7. Sol-air temperature - Wikipedia

    en.wikipedia.org/wiki/Sol-air_temperature

    Sol-air temperature (T sol-air) is a variable used to calculate cooling load of a building and determine the total heat gain through exterior surfaces.It is an improvement over:

  8. Heat advisory - Wikipedia

    en.wikipedia.org/wiki/Heat_advisory

    A heat advisory is a notice issued by the National Weather Service of the United States.Local offices often have their own criteria. High values of the heat index are caused by temperatures being significantly above normal and high humidities, and such high levels can pose a threat to human life through conditions such as heat stroke.

  9. Glossary of HVAC terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_HVAC_terms

    An HVAC component that uses outside air, under suitable climate conditions, to reduce required mechanical cooling. When the outside air’s enthalpy is less than the required supply air during a call for cooling, an economizer allows a building’s mechanical ventilation system to use up to the maximum amount of outside air. enthalpy
