Dynamics and Chemistry of the Summer Stratosphere (DCOTSS)

During the summer, strong convective storms over North America overshoot the tropopause into the lower stratosphere. These storms carry water and pollutants from the troposphere into the normally very dry stratosphere, where they can have a significant impact on radiative and chemical processes, potentially including stratospheric ozone. The photo below, taken from the International Space Station, shows one of these storms with an anvil, which is typically near the tropopause level; an overshooting top; and a plume of cirrus (ice) clouds injected into the stratosphere by the overshooting top. Overshooting tops can reach many kilometers above the tropopause into the stratosphere.
