Abstract: The purpose of this paper is two-fold; first, to document and present a limited-area, moist primitive equation model and, second, to give some preliminary results of experiments testing the sensitivity of the model's ...

Abstract: A process of lee cyclogenesis associated with backsheared baroclinic flow is studied using a fully nonlinear, primitive equation numerical model. A region of low pressure and a narrow baroclinic zone develop to the southwest ...

Abstract: Before high-resolution numerical models can be of use operationally, they must be restricted to a limited domain, thus necessitating lateral boundary conditions which allow the changes outside the limited domain to influence ...

Abstract: The release of potential instability by large-scale lifting and the subsequent interaction of cumulus convection and the hydrostatic mesoscale flow in a most complex scale-interaction process. This process is an essential ...

Abstract: A mesoscale primitive equation model is used to create a 36-h simulation of the three-dimensional wind field of an intense maritime extratropical cyclone. The control experiment uses the simulated wind field every 15 min ...

Abstract: On 25 April 1975, as part of the National Aeronautics and Space Administration's Atmospheric Variability Experiment IV, frequent upper-air soundings were taken at eastern United States synoptic sounding sites. An intense, ...

Abstract: In Part I the convective processes important during the release of potential instability were described qualitatively and evaluated quantitatively in a parameterized cumulus model within a primitive equation model. Part ...

Abstract: Newspapers, television, and newsweeklies contained numerous articles proclaiming drought conditions during 1980 and 1981. This study investigates the causes and consequences of the drought as it affected eastern Pennsylvania. ...

Abstract: The diabatic effects of latent heat release, boundary layer moisture and heat flux from the ocean surface and large-scale forcing due to upper-level systems are three physical processes affecting oceanic cyclogenesis. ...

Abstract: A severe extratropical cyclcone was initiated from a low-level medium-scale cyclone over the ocean northeast of Taiwan during the initial phase of the AMTEX '75. The analyses of Soliz and Fein were used to examine the time ...
