When I check the temperature for my town on the web it gives two numbers-one says 'real feel'. What does that mean and why is the second number usually different from the first?
I've never heard of a 'real feel' temperature before...I have heard of a 'feels like' temperature. Now that temperature usually refers to wind chill during the late autumn through early spring months, and heat stress from late spring through early autumn. Specifically, wind chill interprets the combined effect of temperature and wind; the result is usually cooler than the actual air temperature while heat stress interprets the combined effect of temperature and humidity; the result is usually warmer than the actual air temperature.
