A Composite Mesoscale Cumulonimbus Budget
Publisher: American Meteorological Society
Abstract: Composite maps at levels from 950 to 150 mb of relative wind field (Vτ), mixing ratio (r), equivalent potential temperature (?E), and temperature perturbation (T?) from the growth and decay phases of a mean mesoscale ...
Coupling of the Radiative, Convective, and Surface Fluxes over the Equatorial Pacific
Publisher: American Meteorological Society
Abstract: An idealized energy-balance model for a closed circulation is first presented to illustrate the coupling between the net tropospheric radiative cooling, the surface fluxes and the mean subsidence away from the precipitation ...
Traveling Convective Storms over Venezuela
Publisher: American Meteorological Society
Abstract: The low-level atmospheric transformation associated with a class of traveling convective storms observed. over Venezuela is described. A strong low-level cooling is observed, confined mostly to the subcloud layer, and ...
An Example of Hurricane Tracking and Forecasting with a Global Analysis-Forecasting System
Publisher: American Meteorological Society
Abstract: The tracking of Hurricane Elena by the ECMWF operational analysis system is compared with reported positions from reconnaissance aircraft and coastal radar. An example forecast is shown for the operational model and also ...
Daytime Cycle of Low-Level Clouds and the Tropical Convective Boundary Layer in Southwestern Amazonia
Publisher: American Meteorological Society
Abstract: During the wet season in the southwestern Amazon region, daytime water transport out of the atmospheric mixed layer into the deeper atmosphere is shown to depend upon cloud amounts and types and synoptic-scale velocity ...
Comparison of Ceilometer, Satellite, and Synoptic Measurements of Boundary-Layer Cloudiness and the ECMWF Diagnostic Cloud Parameterization Scheme during ASTEX
Publisher: American Meteorological Society
Abstract: Cloud fraction is a widely used parameter for estimating the effects of boundary-layer cloud on radiative transfer. During the Atlantic Stratocumulus Transition Experiment (ASTEX) during June 1992, ceilometer and satellite-based ...
