Hi. I'm Randall, and I'm here above Utah County in Utah, and you can see all of the hazy air behind me, air that has been trapped by an inversion, or cold air trapped by warmer air above it, and then all of the pollutants from cars and fireplaces. And the only way for this to be swept out is through, uh, perhaps by strong winds coming through.

And during these times, people with respiratory issues including asthma should, uh, limit the amount of time they stay outside. Children at schools are often kept inside for recess, and also people should restrict the amount of driving and take public transportation, so this gets cleaned out.
