Apparent temperature, also known as "feels like", [1] [2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.
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.
What thermostat setting is too cold for below-freezing temperatures outside? Although water freezes at 32 degrees Fahrenheit, it's a good idea to keep your thermostat at 50 degrees or higher.
During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...
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.
Story at a glance A major winter storm is bringing record cold temperatures and winter weather to much of the continental U.S., leading to significant disruptions ahead of the Christmas holiday.
If temperature is below freezing, 0 °C (32 °F), near the ground and up in the clouds, precipitation will fall as snow, ice, rain and snow mixed (sleet), ice pellets or even graupel (soft hail). [1] [2] Since cold air can not hold as much moisture as warm air, the total precipitation will be less than at higher temperature. [3]
At least 246 Texans died during last February’s winter storm. More than half suffered from hypothermia or frostbite. Here’s how to protect yourself.
