2021年9月1日 · Looming in the stratosphere higher than Everest, these billowing clouds of smoke, moisture and gas appear only above the largest megafires, like the hot breath of hell. They lash out with...
AirNow Fire and Smoke Map
Smoke plumes reflect smoke anywhere in the atmosphere, not necessarily near the ground. As such, they may not be associated with bad air quality. Due to a large number of features, you may need to zoom farther in to see certain Fire Information layers of the map. This map shows fine particle pollution (PM2.5) from wildfires and other sources.

Flying through a Fire Cloud - NASA Earth Observatory
Atmospheric scientists regularly take note when satellites detect thunderheads rising above columns of wildfire smoke. These “fire clouds”—experts call them pyrocumulonimbus (pyroCb) or cumulonimbus flammagenitus—are caused when fires loft enough heat and moisture into the atmosphere to produce thunderstorms.
