Welcome to the Birner research group at the Department of Atmospheric Science, at Colorado State University.

Our group explores a range of dynamical phenomena in the coupled troposphere / stratosphere system. Examples include the dynamics that govern the temperature structure of the tropical tropopause layer, the dynamics of sudden stratospheric warmings, eddy(wave)-mean flow interactions and corresponding feedbacks, the stratospheric mean meridional circulation, transport processes in the upper troposphere / lower stratosphere.
