Ueda asks for a definition of the term, “heat index”, and Grace explains the differences between “windchill” and heat index. Ueda also asks why high humidity makes a hot day so unpleasant. And Salmans says that people’s sweat evaporates more slowly on days like that, so they don’t cool off. Grace tells the group how many people die in the U.S. from extreme heat each year.
The term “windchill” describes what the air actually feels like, based on the wind velocity and the dryness of the air.
About 100 people die in the United States from extreme heat each year.
