Abstract: A new method for numerically solving the classical quasi-geostrophic omega equation is proposed. The method, in effect, integrates the omega equation upward using two bottom boundary conditions at the top of the boundary ...

Abstract: Existing methods for calculating synoptic and meso-alpha scale vertical motion rely on upper air sounding data which confines the calculations to restricted regions of the earth's surface and to sounding times. In this ...

Abstract: Balance omega equations have recently been used to try to improve the characterization of balance in variational data assimilation schemes for numerical weather prediction (NWP). Results from Fisher and Fillion et al. ...

Abstract: Any comprehensive numerical model is composed of two parts: a dynamical kernel solving for the fluid mechanical field equations and a physical package to parameterize the ensemble effect of subgrid-scale processes upon the ...

Abstract: This paper examines the 24-h explosive development periods of two extratropical cyclones, the first occurring over the Gulf Stream off the coast of New England from 18 to 19 January 1979 and the second occurring over the ...

Abstract: This study examines a few approaches to isolate the balanced component of the initial corrections from the Canadian Meteorological Centre energy-norm-based key analysis error algorithm, in an attempt to capture the part ...

Abstract: The characteristics of the initial corrections obtained from the Canadian Meteorological Centre (CMC) energy-norm-based key analysis error algorithm that minimizes short-range (24 h) forecast errors were investigated for ...
