Abstract: A Conceptual model of the Saharan Air Layer (SAL) and easterly wave disturbance is presented in light of diagnostic analyses of dust outbreaks. Numerical simulations of the SAL were carried out to 5 days for two case studies ...

Abstract: The formations of Hurricane Andrew, Tropical Storm Ernesto, and Hurricane Luis, which occurred, respectively, during the 1992, 1994, and 1995 hurricane seasons over the eastern Atlantic, have been investigated by utilizing ...

Abstract: The present study uses a regional-scale numerical model to test the impact of dynamically assimilating, satellite-derived precipitation rates on the numerical simulations of one of the deepest extratropical cyclones to ...

Abstract: Numerical simulations were performed with the Pennsylvania State University/National Center for Atmospheric Research Mesoscale Model Version 5 (MM5) to study the impact of initial conditions, satellite-derived rain ...

Abstract: The total (i.e., convective and stratiform) latent heat release (LHR) cycle in the eyewall region of Hurricane Opal (October 1995) has been estimated using observations from the F-10, F-11, and F-13 Defense Meteorological ...

Abstract: Inadequate specification of divergence and moisture in the initial conditions of numerical models results in the well-documented ?spinup? problem. Observational studies indicate that latent heat release can be a key ...

Abstract: Lidar observations collected during the Lidar In-space Technology Experiment experiment in conjunction with the Meteosat and European Centre for Medium-Range Weather Forecasts data have been used not only to validate the ...
