As you go higher into the atmosphere, temperatures usually cool. When you have an inversion, however, temperatures rise as you ascend through the atmosphere.
You can see the inversion on the latest weather balloon “sounding” from Pittsburgh.

Inversions have been getting a lot of attention in the Pittsburgh area lately.
These inversions play a major role in trapping pollution near the Earth’s surface. Usually, these air pollutants are associated with heat, so they rise higher into the atmosphere. When we have a temperature inversion, that heat can no longer lift the pollutants away.
The impacts from air pollution can be minimized by staying indoors and avoiding strenuous, outdoor activities.MORE NEWS: Pittsburgh Native And CEO Of University Of Florida Health CEO Dr. Leon Haley Dies Unexpectedly
