Abstract: A cyclogenesis event that occurred over Colorado in early March of 1981 is the focus of this study. Two features that seemed to play a role in storm initiation were a traveling upper troposphere disturbance associated with ...

Abstract: Quasigeostrophic disturbances on a midlatitude ?-plane channel forced by radiative heating perturbations due to synoptic-scale variations of low-level stratiform cloud are considered. The longitudinal phase of the cloud ...

Abstract: A six-level quasi-geostrophic model including radiative and photochemical processes in the manner suggested by Lindzen and Goody is run from a state of joint radiative-photochemical equilibrium for midwinter conditions. ...

Abstract: The response to pressure falls near a coastline is studied with a linear shallow-water representation of the inversion-capped marine layer. The aim is to examine Catalina eddy development in the southern California bight ...

Abstract: The structure and vertical propagation of a quasi-geostrophic disturbance in the presence of a constant zonal flow which has been distorted by a finite-amplitude forced stationary wave is considered. The vertical structure ...

Abstract: Adiabatic, inviscid, quasi-geostrophic perturbations on a ? plane are forced at some initial time by the switch-on of a vertical velocity or temperature disturbance at the base of a stratified atmosphere. The vertical ...

Abstract: Observed convective systems, such as mesoscale convective complexes (MCCs), often undergo repeated cycles of nocturnal growth and daytime decay especially during the summer. The gravity wave response to these pulsations ...

Abstract: A global model of planetary wave propagation in a spherical atmosphere is used to examine the spectrum of free or resonant planetary waves of the solstitial stratosphere. These free modes are located by forcing the model ...

Abstract: The Catalina eddy that existed from 5 July to 12 July 1987 during FIRE (First ISSCP Regional Experiment) over offshore California is analyzed. There were two stages to the eddy's lifecycle. During the first, from 5 July ...

Abstract: A series of at least daily rocket soundings of the mesosphere at Wallops Island, Virginia (37°50?N, 75°29?W), in August and September 1976 reveal near simultaneity between rapid temperature rises and tropospheric convection ...
