Sun exposure makes it feel hotter than the shaded air temperature because your body absorbs infrared radiation from the sun.

Understanding how temperature is measured is fundamental to the accuracy of weather forecasts and climate monitoring.

Scientists use "wet-bulb temperature" to gauge how extreme heat affects the body. But what is it?

The Wet Bulb Globe Temperature is a more comprehensive way of showing the effect of the heat on your body.

Meteorologists measure the rate of evaporation, and the temperature difference between the “wet bulb” and the “dry bulb,” or air temperature.

One day in August, The Republic sent 13 reporters to measure heat across metro Phoenix. ASU scientists explain why the results aren't precisely right.

Temperature is a measure of the average energy of a collection of particles. So, to answer a question about temperature, we have to find some collection of particles to measure.

To answer this question, let's unpack what temperature actually is. We tend to think of temperature as how hot or cold something is, but it's actually a measure of the energy or vibrations of all ...

As the heat and humidity increase this week, we will hear a lot about the heat index, especially as temperatures come close or surpass the 100-degree mark. The heat index itself is relatively new ...

You need to start learning what the wet-bulb temperature is, as climate change makes the deadly combination of heat and humidity more likely.
