Humidex :
The Humidex, use primarily in Canada, works on the same concept as the Heat
Index. The values are slightly different. The Humidex is defined over a temperature
range of 70°F to 109°F (21°C to 43°C) and a relative humidity range of 20% to 99%.
Outside of this range, the meter will show dashes in the display for the Humidex.
Wind Chill Temperature:
The wind chill temperature (Twc), used by the U.S. and Canadian weather
services, is determined by iterating a model of skin temperature under various
wind speeds and temperatures.
The wind chill temperature is defined over a temperature range of -58°F to
+41°F (-50°C to +5°C) and a wind speed above 176 ft/m (0.9m/s). Outside of this
range, the meter will show dashes in the display for the wind chill temperature.
