Long-Lived Mesoconvective Vortices and Their Environment. Part II: Induced Thermodynamic Destabilization in Idealized Simulations
Publisher: American Meteorological Society
Abstract: Idealized numerical simulations are used to quantify the effect of quasi-balanced lifting arising from the interaction of the ambient vertical shear with midtropospheric cyclonic vortices (MCVs) generated by mesoscale ...
Conservative Split-Explicit Time Integration Methods for the Compressible Nonhydrostatic Equations
Publisher: American Meteorological Society
Abstract: Historically, time-split schemes for numerically integrating the nonhydrostatic compressible equations of motion have not formally conserved mass and other first-order flux quantities. In this paper, split-explicit integration ...
Structure and Evolution of the 22 February 1993 TOGA COARE Squall Line: Numerical Simulations
Publisher: American Meteorological Society
Abstract: In this study a numerical cloud model is used to simulate the three-dimensional evolution of an oceanic tropical squall line observed during the Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere Response Experiment ...
