RISEffects of Cumulus Ensemble and Mesoscale Stratiform Clouds in Midlatitude Convective Systems
Publisher: American Meteorological Society
Abstract: Diagnostic and semiprognostic analyses are performed using OK PRE-STORM (Oklahoma-Kansas Preliminary Regional Experiment for STORM-Central) data to examine the cumulus-environment interaction in midlatitude convective ...
Diagnostic and Semiprognostic Studies of Cumulus Effects in the Presence of Mesoscale Circulations
Publisher: American Meteorological Society
Abstract: Heat and moisture budgets of two mesoscale convective systems of a characteristic horizontal scale of approximately 450 km are studied using the Atmospheric Variability Experiment-Severe Environmental Storms and Mesoscale ...
Effects of Ice Microphysics on Tropical Radiative–Convective–Oceanic Quasi-Equilibrium States
Publisher: American Meteorological Society
Abstract: The effects of ice microphysics on the mean state of tropical atmosphere and ocean are quantified using a coupled cloud?ocean model. The cloud-resolving model (CRM) treats explicitly the cloud-scale dynamics instead of ...
Effects of Vertical Wind Shear on the Cumulus Transport of Momentum: Observations and Parameterization
Publisher: American Meteorological Society
Abstract: Dynamical effects of organized cumulus convection on its environment with vertical wind shear are studied. Analyses of the wind field and momentum budget residual for mesoscale convective systems observed during SESAME and ...
Effects of Convective Processes on GCM Simulations of the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: Weak temporal variability in tropical climates such as the Madden?Julian oscillation (MJO) is one of major deficiencies in general circulation models (GCMs). The uncertainties in the representation of convection and cloud ...
Effects of Surface Albedo on Cloud and Radiation Processes in Cloud-Resolving Model Simulations
Publisher: American Meteorological Society
Abstract: The relationship among the surface albedo, cloud properties, and radiative fluxes is investigated for the first time using a year-long cloud-resolving model (CRM) simulation with the prescribed evolving surface albedo. In ...
Comparison of Moist Static Energy and Budget between the GCM-Simulated Madden–Julian Oscillation and Observations over the Indian Ocean and Western Pacific
Publisher: American Meteorological Society
Abstract: he moist static energy (MSE) anomalies and MSE budget associated with the Madden?Julian oscillation (MJO) simulated in the Iowa State University General Circulation Model (ISUGCM) over the Indian and Pacific Oceans are ...
Two- and Three-Dimensional Cloud-Resolving Model Simulations of the Mesoscale Enhancement of Surface Heat Fluxes by Precipitating Deep Convection
Publisher: American Meteorological Society
Abstract: Two-dimensional (2D) and three-dimensional (3D) cloud-resolving model (CRM) simulations are conducted to quantify the enhancement of surface sensible and latent heat fluxes by tropical precipitating cloud systems for 20 ...
Physical Mechanisms for the Maintenance of GCM-Simulated Madden–Julian Oscillation over the Indian Ocean and Pacific
Publisher: American Meteorological Society
Abstract: he kinetic energy budget is conducted to analyze the physical processes responsible for the improved Madden?Julian oscillation (MJO) simulated by the Iowa State University general circulation models (ISUGCMs). The modified ...
Collective Effects of Organized Convection and Their Approximation in General Circulation Models
Publisher: American Meteorological Society
Abstract: The collective effects of organized convection the environment were estimated using a two-dimensional, two-way nested cloud-resolving numerical model with a large outer domain (4500 km). As initial conditions, the authors ...
