The discussion will address the effects caused by the vertical turbulent mixing in the stratified atmosphere on climatologically significant time scales. It will be demonstrated that the planetary boundary layer (PBL) is an important amplifier of natural and anthropogenic disturbances of the equilibrium climate. Since this amplifier is asymmetric with respect to external heating/cooling forcing, it produce significant statistical effect on the climate variability and trends. This study discloses the dynamical mechanisms and the PBL-response, its physical and geographical patterns and its consequences for the climate change interpretation and modeling.
