  2. File:Temperature-relative humidity chart - PMV method.pdf

    en.wikipedia.org/wiki/File:Temperature-relative...

    English: This chart represents the acceptable combination of air temperature and humidity values, according to the PMV/PPD method in the ASHRAE 55-2010 Standard. The representation is made on a temperature-relative humidity, instead of a standard psychrometric chart.

    en.wikipedia.org/wiki/Template:Climate_chart/How...

    Climate charts provide an overview of the climate in a particular place. The letters in the top row stand for months: January, February, etc. The bars and numbers convey the following information: The blue bars represent the average amount of precipitation (rain, snow etc.) that falls in each month.

  4. Heat index - Wikipedia

    en.wikipedia.org/wiki/Heat_index

    The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade. For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F ...

  5. Humidex - Wikipedia

    en.wikipedia.org/wiki/Humidex

    The humidity adjustment approximately amounts to one Fahrenheit degree for every millibar by which the partial pressure of water in the atmosphere exceeds 10 millibars (10 hPa). At the time the humidex was originally developed in 1965, Canada was still on the Fahrenheit scale , and thus the humidex was originally based on that.

  6. Template:Heat index - Wikipedia

    en.wikipedia.org/wiki/Template:Heat_index

    The Template:Heat_index calculates the heat index, for a specified temperature and relative humidity (parameters 1 & 2), using a formula from the U.S. National Weather Service (NWS). [ 1 ] Science

  7. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.

  8. Humidity indicator card - Wikipedia

    en.wikipedia.org/wiki/Humidity_indicator_card

    This has usually been a blotting paper impregnated with cobalt(II) chloride base; Less toxic alternatives include other chemicals such as cobalt-free chloride base and special plastic films. [1] Humidity indicators are an inexpensive way to indicate or quantify moisture content inside sealed packaging. They are available in many configurations ...

  9. Mahoney tables - Wikipedia

    en.wikipedia.org/wiki/Mahoney_tables

    The Mahoney Tables (Evans, 1999; Evans, 2001) proposed a climate analysis sequence that starts with the basic and widely available monthly climatic data of temperature, humidity and rainfall, such as that found in HMSO (1958) and Pearce and Smith (1990), or data published by national meteorological services, for example SMN (1995).
