Stretching rates and equivalent length near the tropopause
[1] Diagnostics of mixing in the upper troposphere/lower stratosphere region reveal interesting seasonal and interannual variability and illustrate how the subtropical tropopause can be identified with a region of minimum mixing, a partial barrier to the transport of air between the troposphere and stratosphere. Both the strength and the location of this barrier show substantial seasonal variab...
متن کاملConvective generation of cirrus near the tropopause
[1] During the July 2002 CRYSTAL-FACE field program based from Key West, Florida, aircraft measurements showed that long-lived thin tropopause cirrus (TTC) layers were often present above thunderstorm anvils. This paper describes these clouds and explores their possible origins. Measurements showed that the horizontal dimensions of TTC layers were nearly identical to convectively formed anvils ...
متن کاملIsotopes, seasonal signals, and transport near the tropical tropopause
A recent model study (Sherwood and Dessler 2001) found that dehydration of air within energetic overshooting convective cells, followed by slow lofting into the stratosphere, could account for moisture levels in the lower stratosphere and upper troposphere given realistic horizontal transports and diabatic circulations. Here, we present augmented model simulations of transport across the tropic...

متن کاملStratospheric control of upward wave flux near the tropopause
[1] Using an idealized, global primitive equation model of the stratosphere-troposphere system in which all tropospheric variability is surpressed, we demonstrate the existence of internal modes of stratospheric variability. The variability in our model is similar to that observed in the winter stratosphere, consisting of sudden-warming like, wave-driven decelerations of the polar vortex follow...
