Abstract: A two-dimensional primitive equation model of frontogenesis forced by a combination of confluence and horizontal shear is formulated for dry, nearly adiabatic and inviscid conditions. The frontogenetical forcing mechanisms ...

Abstract: Diagnoses are presented of the transverse ageostrophic circulation patterns for two cases from a two-dimensional primitive equation model of frontogenesis forced by a combination of confluence and horizontal shear. The ...

Abstract: The development of frontal zones is examined in a two-dimensional primitive equation model of frontogenesis formulated for dry, nearly adiabatic and inviscid conditions. The model results are interpreted in the context of ...

Abstract: The three-dimensional structure and implied dynamics of a strong tropospheric gravity wave event am studied. It is shown that satellite and continuous surface observations reveal the subsynoptic nature of this ?wave of ...

Abstract: Equations are developed for the temporal rates of change of the magnitudes of vector gradients of potential temperature and absolute momentum projected onto vertical planes transverse to straight frontal zones. Subject to ...

Abstract: The final set of changes to NMC's Regional Analysis and Forecast System (RAFS) is described. The changes include modifications to both the forecast model and the analysis model, as well as development of a Regional Data ...
