The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C (81 °F). In humid conditions, the air feels much hotter, because less perspiration evaporates from the skin. The wind chill factor measures the effect of wind speed on cooling of the human body below 10 °C (50 °F). As airflow increases ...
The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
Wind chill index values for a range of temperatures and wind speeds, from the standard wind chill formula for Environment Canada. Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere.
Compared to wind chill which only describes the cooling effect of wind and temperature, the AccuWeather RealFeel® Temperature also takes into account humidity, precipitation, cloud cover and ...
Take a look at January weather records for freezing temperatures, snow and rain in Cincinnati.
Freezing [1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. This is usually measured at the height of 1.2 metres above the ground surface.
It does not require exposure to cold to develop. Levamisole toxicity is a vasculitis that can appear similar to frostbite. [18] It is caused by contamination of cocaine by levamisole. Skin lesions can look similar those of frostbite, but do not require cold exposure to occur. People who have hypothermia often have frostbite as well. [10]
In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux.It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
