Interaction of a Cumulus Cloud Ensemble with the Large-Scale Environment, Part I
Abstract A theory of the interaction of a cumulus cloud ensemble with the large-scale environment is developed. In this theory, the large-scale environment is divided into the subcloud mixed layer… Expand

Computational Design of the Basic Dynamical Processes of the UCLA General Circulation Model
TLDR
The 12-layer UCLA general circulation model encompassing troposphere and stratosphere (and superjacent 'sponge layer') is described. Expand

Computational design for long-term numerical integration of the equations of fluid motion: two-dimen
The integral constraints on quadratic quantities of physical importance, such as conservation of mean kinetic energy and mean square vorticity, will not be maintained in finite difference analogues… Expand

A Potential Enstrophy and Energy Conserving Scheme for the Shallow Water Equations
Abstract To improve the simulation of nonlinear aspects of the flow over steep topography, a potential enstrophy and energy conserving scheme for the shallow water equations is derived. It is pointed… Expand

Breaking the Cloud Parameterization Deadlock
A key factor limiting the reliability of simulations of anthropogenic climate change is the inability to accurately represent the various effects of clouds on climate. Despite the best efforts of t...

Peruvian stratus clouds and the tropical Pacific circulation
Abstract Extensive and persistent stratus cloud decks are prominent climatic features off the Peruvian coast. They are believed to play a key role in the coupled atmosphere-ocean processes that… Expand

The parameterization of the planetary boundary layer in the UCLA general circulation model - Formulation and results
Abstract A planetary boundary layer (PBL) parameterization for general circulation models (GCMs) is presented. It uses a mixed-layer approach in which the PBL is assumed to be capped by… Expand
