Abstract: Transport of momentum by convection is an important process affecting global circulation. Owing to the lack of global observations, the quantification of the impact of this process on the tropospheric climate is difficult. ...

Abstract: his study investigates gravity wave spectral characteristics based on high-resolution mesoscale simulations of idealized moist baroclinic jet?front systems with varying degrees of convective instability, with the intent ...

Abstract: This study documents the contribution of equatorial waves and mesoscale gravity waves to the momentum budget of the quasi-biennial oscillation (QBO) in a 110-level version of the Whole Atmosphere Community Climate Model. ...

Abstract: haracteristic properties of gravity waves from convection over the continental United States are derived from idealized high-resolution numerical simulations. In a unique modeling approach, waves are forced by a realistic ...

Abstract: The NCAR Community Climate System Model, version 3 (CCSM3) exhibits persistent errors in its simulation of the El Niño?Southern Oscillation (ENSO) mode of coupled variability. The amplitude of the oscillation is too strong, ...

Abstract: Middle atmospheric general circulation models (GCMs) must employ a parameterization for small-scale gravity waves (GWs). Such parameterizations typically make very simple assumptions about gravity wave sources, such as ...

Abstract: Some parameterizations of gravity wave mean flow forcing in global circulation models (GCMs) add realism by describing wave generation by tropospheric convection. Because the convection in GCMs is itself a parameterized ...
