  2. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 g (1.1 oz) per cubic metre when the air is saturated at 30 °C (86 °F). [8] [9] Air is a gas, and its volume varies with pressure and temperature, per Boyles law. Absolute humidity is defined as water mass per volume of air ...

  3. Santa Ana winds - Wikipedia

    en.wikipedia.org/wiki/Santa_Ana_winds

    The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".

  4. Climate of Houston - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Houston

    The coldest weather of the season often includes temperatures in the low 30s to mid-40s at night. Hard freezes are not uncommon in North Houston; George Bush Intercontinental Airport has recorded at least one freeze every winter since it opened in 1969, except for 2023, when the lowest was 33 degrees.

  5. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements that have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at ...

  6. Hygroscopy - Wikipedia

    en.wikipedia.org/wiki/Hygroscopy

    The word hygroscopy (/ h aɪ ˈ ɡ r ɒ s k ə p i /) uses combining forms of hygro-(for moisture or humidity) and -scopy. Unlike any other -scopy word, it no longer refers to a viewing or imaging mode. It did begin that way, with the word hygroscope referring in the 1790s to measuring devices for humidity level. These hygroscopes used ...

  7. Humid subtropical climate - Wikipedia

    en.wikipedia.org/wiki/Humid_subtropical_climate

    A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...

  8. Transpiration - Wikipedia

    en.wikipedia.org/wiki/Transpiration

    2) Decreased relative humidity outside the leaf will increase the water potential gradient. Relative humidity: Drier surroundings give a steeper water potential gradient, and so increase the rate of transpiration. Wind: In still air, water lost due to transpiration can accumulate in the form of vapor close to the leaf surface.

  9. Climate of Brisbane - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Brisbane

    In 2009, Brisbane recorded its hottest winter day (from June to August) at 35.4 °C (95.7 °F) on 24 August; [13] The average July day however is around 22 °C (72 °F) with sunny skies and low humidity, occasionally as high as 27 °C (81 °F), whilst maximum temperatures below 18 °C (64 °F) are uncommon and usually associated with brief ...
