RISThe Double-ITCZ Problem in IPCC AR4 Coupled GCMs: Ocean–Atmosphere Feedback Analysis
Publisher: American Meteorological Society
Abstract: This study examines the double?intertropical convergence zone (ITCZ) problem in the coupled general circulation models (CGCMs) participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report ...
Stratocumulus Clouds in Southeastern Pacific Simulated by Eight CMIP5–CFMIP Global Climate Models
Publisher: American Meteorological Society
Abstract: his study examines the stratocumulus clouds and associated cloud feedback in the southeast Pacific (SEP) simulated by eight global climate models participating in phase 5 of the Coupled Model Intercomparison Project (CMIP5) ...
Radiation Budget of the Tropical Intraseasonal Oscillation
Publisher: American Meteorological Society
Abstract: This study examines the relationship between precipitation and radiative heating on intraseasonal time scales in the Tropics using collocated top-of-atmosphere (TOA) and surface radiative flux measurements from special ...
Zonal Momentum Budget of the Madden–Julian Oscillation: The Source and Strength of Equivalent Linear Damping
Publisher: American Meteorological Society
Abstract: Linear, dissipative models with resting base states are sometimes used in theoretical studies of the Madden?Julian oscillation (MJO). Linear mechanical damping in such models ranges from nonexistent to strong, since an ...
What Are the Sources of Mechanical Damping in Matsuno–Gill-Type Models?
Publisher: American Meteorological Society
Abstract: The Matsuno?Gill model has been widely used to study the tropical large-scale circulations and atmosphere?ocean interactions. However, a common critique of this model is that it requires a strong equivalent linear mechanical ...
Sea Surface Temperature Biases under the Stratus Cloud Deck in the Southeast Pacific Ocean in 19 IPCC AR4 Coupled General Circulation Models
Publisher: American Meteorological Society
Abstract: his study examines systematic biases in sea surface temperature (SST) under the stratus cloud deck in the southeast Pacific Ocean and upper-ocean processes relevant to the SST biases in 19 coupled general circulation models ...
Is the Tropical Atmosphere in Convective Quasi-Equilibrium?
Publisher: American Meteorological Society
Abstract: he hypothesis of convective quasi-equilibrium (CQE) has dominated thinking about the interaction between deep moist convection and the environment for at least two decades. In this view, deep convection develops or decays ...
The Impacts of Convective Parameterization and Moisture Triggering on AGCM-Simulated Convectively Coupled Equatorial Waves
Publisher: American Meteorological Society
Abstract: This study examines the impacts of convective parameterization and moisture convective trigger on convectively coupled equatorial waves simulated by the Seoul National University (SNU) atmospheric general circulation model ...
Intraseasonal Variation of Winter Precipitation over the Western United States Simulated by 14 IPCC AR4 Coupled GCMs
Publisher: American Meteorological Society
Abstract: This study evaluates the intraseasonal variation of winter precipitation over the western United States in 14 coupled general circulation models (GCMs) participating in the Intergovernmental Panel on Climate Change (IPCC) ...
MJO and Convectively Coupled Equatorial Waves Simulated by CMIP5 Climate Models
Publisher: American Meteorological Society
Abstract: his study evaluates the simulation of the Madden?Julian oscillation (MJO) and convectively coupled equatorial waves (CCEWs) in 20 models from the Coupled Model Intercomparison Project (CMIP) phase 5 (CMIP5) in the ...
