Gravity Waves in Shear and Implications for Organized Convection
It is known that gravity waves in the troposphere, which are often excited by preexisting convection, can favor or suppress the formation of new convection. Here it is shown that, in the presence of wind shear or barotropic wind, the gravity waves can create a more favorable environment on one side of preexisting convection than the other side. Both the nonlinear and linear analytic models deve...
متن کاملThe Effect of Moist Convection on the Tropospheric Response to Tropical and Subtropical Zonally Asymmetric Torques
Tropospheric winds can be altered by vertical transfers of momentum due to orographic gravity waves and convection. Previous work showed that, in dry models, such zonally asymmetric torques produce a pattern of tropical ascent that is well described by linear dynamics, together withmeridional shifts of the midlatitude jet. Here a series of idealizedmodels is used to understand the effects of mo...
متن کاملSolar wind Alfvén waves: a source of pulsed ionospheric convection and atmospheric gravity waves
A case study of medium-scale travelling ionospheric disturbances (TIDs) that are correlated with solar wind Alfvén waves is presented. The HF radar groundscatter signatures of TIDs caused by atmospheric gravity waves with periods of 20–40 min are traced to a source at high latitudes, namely pulsed ionospheric flows (PIFs) due to bursts in the convection electric field and/or the associated iono...
متن کاملBurnout in Forced Convection
Data are presented for burnout in forced coivection nucleate boiling of water at pressures above 500 psia. A dimensionless correlation is devised for. the M.I.T. data which is found to be valid for certain recent data reported by Argonne National Laboratory.
متن کاملGeneration and Trapping of Gravity Waves from Convection with Comparison to Parameterization
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 process, these convectively generated wave parameterizations necessarily use many simplifying assumptions. In this work, the authors use a realistic simulation of wave generatio...
