A volcanogenic intensification factor of stratosphere-troposphere exchange

A mechanism of volcanic aerosol transport to the stratosphere after Plinian-type eruptions, when the maximal height of the emission does not exceed the tropopause altitude, is suggested. The NOAA HYSPLIT trajectory model and open global temperature data are used in order to show the role of the volc...

Summary:A mechanism of volcanic aerosol transport to the stratosphere after Plinian-type eruptions, when the maximal height of the emission does not exceed the tropopause altitude, is suggested. The NOAA HYSPLIT trajectory model and open global temperature data are used in order to show the role of the volcanic gas-ash clouds in the temperature change of the upper troposphere and lower stratosphere, tropopause destruction, and, as a consequence, intensification of the stratosphere-troposphere exchange. An abnormal increase in surface ozone concentrations is recorded during the passage of volcanic clouds.
