Convective mixing near the tropical tropopause: Insights from seasonal variations

Sherwood and Dessler present an explicit model of the interaction between overshooting convection and large-scale processes. They emphasized the importance of a tropical tropopause layer between about 14 and 19 km, rather than a specific tropopause or other surface, as the true mediator or exchange...

Zusammenfassung:	Sherwood and Dessler present an explicit model of the interaction between overshooting convection and large-scale processes. They emphasized the importance of a tropical tropopause layer between about 14 and 19 km, rather than a specific tropopause or other surface, as the true mediator or exchange between the troposphere and stratosphere.
