Convectively Coupled Waves in a Sheared Environment
Publisher: American Meteorological Society
Abstract: A linear stability analysis, about a radiative?convective equilibrium in a sheared environment, on an equatorial beta plane, for a simple multicloud model for organized tropical convection is presented here. Both ...
Equatorial Convectively Coupled Waves in a Simple Multicloud Model
Publisher: American Meteorological Society
Abstract: Linear stability results for the multicloud model recently developed by the authors on an equatorial beta plane are presented here. The linearized equations, about a realistic radiative?convective equilibrium (RCE) are ...
A Simple Multicloud Parameterization for Convectively Coupled Tropical Waves. Part I: Linear Analysis
Publisher: American Meteorological Society
Abstract: Recent observational analysis reveals the central role of three multicloud types, congestus, stratiform, and deep convective cumulus clouds, in the dynamics of large-scale convectively coupled Kelvin waves, westward-propagating ...
Boundary Layer Dynamics in a Simple Model for Convectively Coupled Gravity Waves
Publisher: American Meteorological Society
Abstract: A simplified model of intermediate complexity for convectively coupled gravity waves that incorporates the bulk dynamics of the atmospheric boundary layer is developed and analyzed. The model comprises equations for velocity, ...
Organized Convection Parameterization for the ITCZ
Publisher: American Meteorological Society
Abstract: esoscale convective systems (MCSs) are of fundamental importance in the dynamics of the atmospheric circulation and the climate system. They are often observed to develop over significant terrain in ambient shear flows in ...
A Simple Multicloud Parameterization for Convectively Coupled Tropical Waves. Part II: Nonlinear Simulations
Publisher: American Meteorological Society
Abstract: Observations in the Tropics point to the important role of three cloud types, congestus, stratiform, and deep convective clouds, besides ubiquitous shallow boundary layer clouds for both the climatology and large-scale ...
Models for Multiscale Interactions. Part I: A Multicloud Model Parameterization
Publisher: American Meteorological Society
Abstract: n this chapter, a model parameterization for organized tropical convection and convectively coupled tropical waves is presented. The model is based on the main three cloud types, congestus, deep, and stratiform, that are ...
The Deepening of Tropical Convection by Congestus Preconditioning
Publisher: American Meteorological Society
Abstract: The role of environmental moisture in the deepening of cumulus convection is investigated by means of cloud-resolving numerical experiments. Under idealized conditions of uniform SST and specified radiative cooling, the ...
Multicloud Models for Organized Tropical Convection: Enhanced Congestus Heating
Publisher: American Meteorological Society
Abstract: Despite the recent advances in supercomputing, the current general circulation models (GCMs) poorly represent the large-scale variability associated with tropical convection. Multicloud model convective parameterizations ...
Using the Stochastic Multicloud Model to Improve Tropical Convective Parameterization: A Paradigm Example
Publisher: American Meteorological Society
Abstract: espite recent advances in supercomputing, current general circulation models (GCMs) poorly represent the variability associated with organized tropical convection. A stochastic multicloud convective parameterization based ...
