Abstract: Intraseasonal variability of the tropical cold-point tropopause (CPT) and its relationship with tropical convection are investigated. Negative CPT temperature anomalies lead negative outgoing longwave radiation anomalies ...

Abstract: Observations and model results indicate that the quasi-biennial oscillation (QBO) modulation of stratospheric water vapor results from two causes. Dynamical redistribution of water vapor from the QBO-induced mean meridional ...

Abstract: Clouds cool the climate system by reflecting shortwave radiation and warm it by increasing the atmospheric greenhouse. Previous studies have shown that in tropical regions of deep convection there is a near cancellation ...
