Energy Accumulation and Emanation at Low Latitudes. Part II: Nonlinear Response to Strong Episodic Equatorial Forcing
Publisher: American Meteorological Society
Abstract: A fully nonlinear model is used to reexamine the impact of a zonally varying basic state on the propagation characteristics of latitudinally equatorially trapped modes. Linear studies have shown that such modes are ...
Energy Accumulation and Emanation at Low Latitudes. Part III: Forward and Backward Accumulation
Publisher: American Meteorological Society
Abstract: Short equatorially trapped Rossby waves are usually thought to he trapped and dissipated nea the region of creation because of their relatively slow group speeds and because of the relatively low amplitude basic state ...
Equatorial Energy Accumulation and Emanation Regions: Impacts of a Zonally Varying Basic State
Publisher: American Meteorological Society
Abstract: Previous studies have suggested that the regions of mean anomalous perturbation kinetic energy which exist in the vicinity of the equatorial upper-tropospheric westerlies are the result of the propagation of extratropical ...
Transitions in Shallow Convection: An Explanation for Lateral Cell Expansion
Publisher: American Meteorological Society
Abstract: A generalized seven-coefficient model of two-dimensional Rayleigh-Bénard convection is presented. The model simulates successfully one means by which lateral cell expansion can occur as the value of the imposed vertical ...
Compact Spatial Differencing Techniques in Numerical Modeling
Publisher: American Meteorological Society
Abstract: The accuracies of the usual centered differencing, compact differencing and finite element methods are compared linearly with a geostrophic adjustment problem and nonlinearly with a vorticity advection problem. The finite ...
A Two-Way Interactive Nesting Procedure with Variable Terrain Resolution
Publisher: American Meteorological Society
Abstract: A two-way interactive, nested-grid system tested with The Pennsylvania Slate University/INCAR three-dimensional mesoscale model is described. A mesh structure, designed to minimize numerical noise, together with a procedure ...
Extended-Range Probabilistic Forecasts of Ganges and Brahmaputra Floods in Bangladesh
Publisher: American Meteorological Society
Abstract: The authors have developed a new extended-range flood forecasting system for large river basins that uses satellite data and statistically rendered probabilistic weather and climate predictions to initialize basin-scale ...
