Abstract: A procedure is introduced which allows estimation of the net influence of subgrid-scale thermodynamic processes on large-scale available potential energy. A numerical example representing the average energetics over North ...

Abstract: Several techniques exist for computing vertical motions. In this paper, radiosonde wind observations are used to compute vertical motions by the kinematic method. The presence of cumulative bias errors necessitates adjustment ...

Abstract: The kinetic energy budgets of several examples of synoptic scale systems are reviewed. Included are systems containing a major cyclone development, the immediate cyclone vicinity, and the anticyclone preceding the cyclone ...

Abstract: Diagnostic and modeling results reveal that atmospheric heating typically acts to intensify extratropical cyclones. In addition, both the Petterssen?Sutcliffe and Zwack?Okossi development equations reveal that this ...

Abstract: A technique is proposed for computing horizontal velocity divergence and the vertical component of vorticity from radiosonde wind data. Utilizing a quadratic Taylor's series representation of the horizontal wind field, one ...

Abstract: ?Least-squares? approximating polynomials are used to suppress bias and random errors in estimating vertical profiles of winds, divergence, and vertical motion. A quadratic polynomial is used to filter each wind profile. ...

Abstract: A kinetic energy budget over North America is computed using standard rawinsonde data during 11?24 April 1970, a period of repeated short synoptic wave development. A comparative analysis with energy transformation documented ...

Abstract: AbstractMeridional diffusivity is assessed for a baroclinically unstable jet in a high-latitude idealized circumpolar current (ICC) using the Model for Prediction across Scales Ocean (MPAS-O) and the online Lagrangian in ...

Abstract: This Paper Presents a statistical diagnosis of the differences between two Goddard Laboratory for Atmospheres analysis representations of temperature and wind speed, one containing satellite data influences (SAT analyses) ...
