    en.wikipedia.org/wiki/Glossary_of_meteorology

    Also apparent temperature, felt air temperature, and humiture. A meteorological index that posits the apparent temperature perceived by the average human being who is exposed to a given combination of air temperature and relative humidity in a shaded area. For example, when the air temperature is 32 °C (90 °F) with 70% relative humidity, the ...

  3. Cold shrinking - Wikipedia

    en.wikipedia.org/wiki/Cold_shrinking

    Cold shrinking is mostly done by use of a dolly hammer. [2] The resulting rough surface is filled using a body filler or a body solder for a smoother finish. [3] Cold shrinking is a method of panel beating where heating is not done to the stretched panel. This method is mostly suitable for integral cars with integral body panels such as ...

  4. Frost heaving - Wikipedia

    en.wikipedia.org/wiki/Frost_heaving

    Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).

  5. Severe weather terminology (United States) - Wikipedia

    en.wikipedia.org/wiki/Severe_weather_terminology...

    Extreme cold warning NPW – Dangerously cold air temperatures and/or wind chills, capable of causing life-threatening medical conditions (such as severe frostbite and hypothermia) or death associated with accelerated heat loss from exposed skin, are forecast to meet or exceed locally defined warning criteria for more than three hours over at ...

  6. List of severe weather phenomena - Wikipedia

    en.wikipedia.org/wiki/List_of_severe_weather...

    Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.

  7. Cold wave - Wikipedia

    en.wikipedia.org/wiki/Cold_wave

    A cold wave (known in some regions as a cold snap, cold spell or Arctic Snap) is a weather phenomenon that is distinguished by a cooling of the air. Specifically, as used by the U.S. National Weather Service , a cold wave is a rapid fall in temperature within a 24-hour period requiring substantially increased protection to agriculture, industry ...

  8. Cryobiology - Wikipedia

    en.wikipedia.org/wiki/Cryobiology

    Cryobiology is the branch of biology that studies the effects of low temperatures on living things within Earth's cryosphere or in science. The word cryobiology is derived from the Greek words κρῧος [kryos], "cold", βίος [bios], "life", and λόγος [logos], "word".

  9. Cold hardening - Wikipedia

    en.wikipedia.org/wiki/Cold_hardening

    Cold increases cell membrane permeability [4] and makes the cell shrink, as water is drawn out when ice is formed in the extracellular matrix between cells. [2] To retain the surface area of the cell membrane so it will be able to regain its former volume when temperature rises again, the plant forms more and stronger Hechtian strands .
