Modeling Study of a Tropical Squall-Type Convective Line
Publisher: American Meteorological Society
Abstract: A multidimensional and time-dependent cloud scale model is used to investigate the dynamic and micro-physical processes associated with convective and stratiform regions within a tropical squall-type convective line. The ...
Cloud Interactions and Merging: Numerical Simulations
Publisher: American Meteorological Society
Abstract: A total of 48 numerical experiments have been performed to study cloud interactions and merging by means of a two-dimensional multi-cell model. Two soundings of deep convection during GATE and two different magnitudes of ...
A Further Study of Cumulus Interactions and Mergers: Three-Dimensional Simulations with Trajectory Analyses
Publisher: American Meteorological Society
Abstract: A total of nine three-dimensional experiments are made to study cloud interaction and merging under the influence of different imposed conditions. Large-scale lifting forcing, environmental wind shear and cloud microphysical ...
An Equation for Moist Entropy in a Precipitating and Icy Atmosphere
Publisher: American Meteorological Society
Abstract: This paper addresses an equation for moist entropy in the framework of cloud-resolving models. After rewriting the energy equation with moist entropy in the place of temperature, an equation for moist entropy is obtained. ...
Sensitivity of High-Resolution Simulations of Hurricane Bob (1991) to Planetary Boundary Layer Parameterizations
Publisher: American Meteorological Society
Abstract: The fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model is used to simulate Hurricane Bob (1991) using grids nested to high resolution (4 km). Tests are conducted to ...
A Numerical Study of the Vertical Transport of Momentum in a Tropical Rainband
Publisher: American Meteorological Society
Abstract: The vertical transport of horizontal momentum in a convective tropical rainband is studied using a two-dimensional cloud ensemble model. Twelve simulations are made under the same large-scale conditions. The vertical ...
A Study of the Response of Deep Tropical Clouds to Mesoscale Processes: Three-Dimensional Numerical Experiments
Publisher: American Meteorological Society
Abstract: A three-dimensional numerical cloud ensemble model has been developed to investigate the collective feedback effects of cloud systems on the large-scale environment. An observed large-scale lifting is imposed continuously ...
The Impact of Ocean Surface Fluxes on a TOGA COARE Convective System
Publisher: American Meteorological Society
Abstract: A two-dimensional cloud-resolving model is linked with a TOGA COARE flux algorithm to examine the impact of the ocean surface fluxes on the development of a tropical squall line and its associated precipitation processes. ...
A Parameterization for the Triggering of Landscape-Generated Moist Convection. Part II: Zero-Order and First-Order Closure
Publisher: American Meteorological Society
Abstract: To improve the triggering of clouds over landscape heterogeneity, it is suggested that the forcing by mesoscale circulations generated by landscape patches be included. For this purpose, it is suggested that a relatively ...
The Next-Generation Goddard Convective–Stratiform Heating Algorithm: New Tropical and Warm-Season Retrievals for GPM
Publisher: American Meteorological Society
Abstract: AbstractThe Goddard convective?stratiform heating (CSH) algorithm, used to estimate cloud heating in support of the Tropical Rainfall Measuring Mission (TRMM), is upgraded in support of the Global Precipitation Measurement ...
