Abstract: High-resolution visible imagery for the eastern GOES satellite is used to document a convectively driven mesoscale weather system which propagates against the mean atmospheric flow and produces an apparent spiraling anvil outflow.

Abstract: A fine-mesh, 20-level, primitive equation model is used to study the generation of convectively driven weather systems in the vicinity of the tropopause. In a test simulation, a high-level (?200 mb) mesoscale high pressure ...

Abstract: Examination of NMC upper tropospheric analyses (300, 200 and 150 mb charts) indicates that significant perturbations are present in the wind fields in the vicinity of intense meso-α scale (250?2500 km) thunder-storm complexes ...

Abstract: An intense mesoscale convective complex developed over the central Mississippi Valley during the night and early morning hours of 24 and 25 April 1975. Analyses of upper tropospheric features during this period indicate ...

Abstract: The character of cloud-to-ground lightning is examined during the life cycle of a distinct mesoscale segment of the 10?11 June 1985 mesoscale convective system (MCS). Three phases of lightning activity are identified and ...

Abstract: Rainfall evolution and diurnal variation are important components in the North American monsoon system (NAMS). In this study these components are numerically studied using the fifth-generation Pennsylvania State ...

Abstract: Satellite images are used to document the life cycles of Mesoscale Convective Complexes (MCCs) which occurred over the United States during the warm season months of 1981. These systems were found to exhibit characteristics ...

Abstract: In this article, four continually processed sea surface temperature (SST) datasets, including the Reynolds SST (RYD), the global final analysis of skin temperature at oceans (FNL), and two Moderate Resolution Imaging ...

Abstract: The return of tropical air from the Gulf of Mexico is examined in the autumnal cool season. Results from the thermodynamic equilibrium model of Betts and Ridgway are used to calculate the equilibrium equivalent potential ...

Abstract: Meteorological conditions associated with more than 150 intense convective precipitation events have been examined. These heavy rainfalls caused flash floods and affected most geographic regions of the conterminous United ...
