A heat dome is an exceptionally warm air mass that forms when a strong high pressure system in the upper atmosphere “sits” in one spot for days or even weeks. On the other end of the spectrum, most healthy adults can tolerate higher temperatures, provided they have access to rest, water, shade, and cool spaces.

But why is the stratosphere increasingly chill? The basic concept is easy to grasp though.
