Relative humidity is an important metric used in weather forecasts and reports, as it is an indicator of the likelihood of precipitation, dew, or fog. In hot summer weather, a rise in relative humidity increases the apparent temperature to humans (and other animals) by hindering the evaporation of perspiration from the skin.
This approach is accurate to within about ±1 °C as long as the relative humidity is above 50%: ; (); This can be expressed as a simple rule of thumb: For every 1 °C difference in the dew point and dry bulb temperatures, the relative humidity decreases by 5%, starting with RH = 100% when the dew point equals the dry bulb temperature.
The lowest amounts occur near the northern borders with Vermont and Ontario, ... Source 1: NOAA (relative humidity and sun 1961–1990; dew point 1965–1984) [39 ...
Good morning, Chicago. The week is going to close out hot and humid. Temperatures will reach the high 90s today and tomorrow, but the high humidity will make it feel hotter than what the ...
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.
T w = Natural wet-bulb temperature (combined with dry-bulb temperature indicates humidity) T g = Globe thermometer temperature (measured with a globe thermometer, also known as a black globe thermometer) T d = Dry-bulb temperature (actual air temperature) Temperatures may be in either Celsius or Fahrenheit; Indoors the following formula is used:
Humidity is the amount of water vapor in the air. The vapor content of air is measured with devices known as hygrometers. The measurements are usually expressed as specific humidity or percent relative humidity. The temperatures of the atmosphere and the water surface determine the equilibrium vapor pressure; 100% relative humidity occurs when ...
The frost-free growing season ranges from 140 days in parts of central Massachusetts to near 160 days across interior Connecticut and inland Rhode Island. [ 2 ] Southern Rhode Island and southern Connecticut are the transition zone from continental climates to the north, to temperate climates (called subtropical in some climate classifications ...
