The Slow Sea Surface Temperature Mode and the Fast-Wave Limit: Analytic Theory for Tropical Interannual Oscillations and Experiments in a Hybrid Coupled Model
Publisher: American Meteorological Society
Abstract: A modified shallow water model with simplified mixed layer dynamics and a sea surface temperature (SST) equation is employed to gain a theoretical understanding of the modes and mechanisms of coupled air-sea interaction ...
A Hybrid Coupled General Circulation Model for El Niño Studies
Publisher: American Meteorological Society
Abstract: A model is developed for tropical air?sea interaction studies, which is intermediate in complexity between the large coupled general circulation models (coupled GCMs) coming into use and the simple two-level models with ...
Deep Convective Organization, Moisture Vertical Structure, and Convective Transition Using Deep-Inflow Mixing
Publisher: American Meteorological Society
Abstract: AbstractIt is an open question whether an integrated measure of buoyancy can yield a strong relation to precipitation across tropical land and ocean, across the seasonal and diurnal cycles, and for varying degrees of ...
A Quasi-Equilibrium Tropical Circulation Model—Formulation
Publisher: American Meteorological Society
Abstract: A class of model for simulation and theory of the tropical atmospheric component of climate variations is introduced. These models are referred to as quasi-equilibrium tropical circulation models, or QTCMs, because they ...
Analyzing ENSO Teleconnections in CMIP Models as a Measure of Model Fidelity in Simulating Precipitation
Publisher: American Meteorological Society
Abstract: he accurate representation of precipitation is a recurring issue in climate models. El Niño?Southern Oscillation (ENSO) precipitation teleconnections provide a test bed for comparison of modeled to observed precipitation. ...
Mechanisms Limiting the Northward Extent of the Northern Summer Monsoons over North America, Asia, and Africa
Publisher: American Meteorological Society
Abstract: Mechanisms determining the poleward extent of summer monsoon convergence zones for North America, Asia, and Africa are examined in an intermediate atmospheric model coupled with a simple land model and a mixed layer ocean. ...
The Scatter in Tropical Average Precipitation Anomalies
Publisher: American Meteorological Society
Abstract: Tropical mean precipitation anomalies ?P?? for 3-month averages appear quite scattered in relation to tropical average sea surface temperature (SST) anomalies ?Ts??, based on examination of a number of observational datasets ...
Analytical Prototypes for Ocean–Atmosphere Interaction at Midlatitudes. Part II: Mechanisms for Coupled Gyre Modes
Publisher: American Meteorological Society
Abstract: A simple midlatitude coupled model for idealized ocean basins is used to investigate processes of ocean?atmosphere interaction and its role in interdecadal climate variability at midlatitudes. The ocean model consists of ...
