The namesake sudden warmi
The namesake sudden warming of this region accompanies a sudden slowing down of the polar vortex in the Northern Hemisphere, and may be caused by upward propagating Rossby waves. The lack of weather in this region, which possesses mostly horizontal winds, is caused by a lack of convection. Discovered by Léon de Bort, it begins where the temperature lapse rate becomes zero, the tropopause. Located directly below the mesosphere, FTP, identify this region of Earth's atmosphere which contains the ozone layer.
