Abstract: Models of wave-CISK are developed that possess a prescribed form for the vertical profile of the diabatic heating due to a cumulus cloud ensemble, and either an explicit or an implicit moisture budget constraint. A comparison ...

Abstract: A study is made of the stability properties of certain coupled and decoupled nonlinear diffusion equations. The equations are of the form currently used in many high-resolution models to parameterize the stably stratified ...

Abstract: A brief critical assessment is presented of several lateral boundary schemes currently employed in regional weather prediction models. Simple flow models are used to determine the nature and cause of the primary shortcomings ...

Abstract: two-component study is undertaken of the classical quasigeostrophic (QG) omega equation. First, a reappraisal is undertaken of extant formulations of the equation?s so-called forcing function. It pinpoints shortcomings of ...

Abstract: An instability of a cold front possessing a low-level warm-band precursor is examined within an f-plane, quasi- and semigeostrophic framework. The basic frontal state is taken to be two-dimensional and of uniform potential ...

Abstract: A strategy is outlined to explore the contribution of errors in the specification of tropopause-level flow features to the misforecast of individual synoptic and subsynoptic weather systems. The approach is founded upon a ...

Abstract: A theoretical study is undertaken of the relative influence of intermediate-level, near-surface, and tropopause-level perturbations upon flow development and cyclogenesis. The study is based upon two complementary ...

Abstract: onsideration is given to the diagnosis and dynamics of synoptic and subsynoptic forecast error from a potential vorticity (PV) perspective. A depiction of the extratropical ?forecast minus analysis? PV pattern on a ...

Abstract: A three-part study of the anomalously cold European winter of 2005/06 is undertaken. Climatological analysis indicates that the dominant pattern of climate variability in the Euro?Atlantic sector during this winter was not ...
