Observationally derived and general circulation model simulated tropical stratospheric upward mass fluxes

[1] We quantify the vertical velocity and upward mass flux in the tropical lower stratosphere on the basis of accurate radiative heating rate calculations using 8-year Southern Hemisphere Additional Ozonesondes balloon-borne measurements of temperature and ozone and cryogenic frost-point hygrometer measured water vapor in the tropics (15 S—10 N). The impact of tropospheric clouds on the stratos...

Inter-model comparison of subseasonal tropical variability in aquaplanet experiments: Effect of a warm pool

This study compares the simulation of subseasonal tropical variability by a set of six state-of-the-art AGCMs in two experiments in aquaplanet configuration: a zonally symmetric experiment, and an experiment with a warm pool centered on the equator. In all six models, the presence of the warm pool generates zonal asymmetries in the simulated mean states in the form of a ‘‘Gill-type’’ response, ...
