A Systematic Relationship between Intraseasonal Variability and Mean State Bias in AGCM Simulations
Systematic relationships between aspects of intraseasonal variability (ISV) and mean state bias are shown in a number of atmospheric general circulation model (AGCM) simulations. When AGCMs are categorized as either strong ISV or weak ISV models, it is shown that seasonal mean precipitation patterns are similar among models in the same group but are significantly different from those of the oth...
متن کاملAdaptive simulations of trade cumulus convection
Many problems in meteorology are being studied with the use of mesh reenement to focus computational eeort on particular regions within the domain. This paper presents a form of adaptive mesh reenement based on hierarchical reenement in space and time for studying atmospheric con-vection and other geophysical ows where the phenomena of interest occupy a small but spatially distributed fraction ...
متن کاملTropical Intraseasonal Variability in Version 3 of the GFDL Atmosphere Model 4 5 6
24 25 Tropical intraseasonal variability is examined in version 3 of the Geophysical Fluid Dynamics 26 Laboratory Atmosphere Model (AM3). Compared to its predecessor AM2, AM3 uses a new treatment 27 of deep and shallow cumulus convection and mesoscale clouds. The AM3 cumulus parameterization is 28 a mass flux-based scheme but also, unlike that in AM2, incorporates subgrid-scale vertical velocit...
متن کاملThe Impacts of Convective Parameterization and Moisture Triggering on AGCM-Simulated Convectively Coupled Equatorial Waves
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 (AGCM). Three different convection schemes are used, including the simplified Arakawa–Schubert (SAS) scheme, the Kuo (1974) scheme, and the moist convective adjustment (MCA) ...
متن کاملSensitivity of Climate Simulations to the Parameterization of Cumulus Convection in the Canadian Climate Centre General Circulation Model
A simplified cumulus parameterization scheme, suitable for use in GCMs, is presented. This parameterization is based on a plume ensemble concept similar to that originally proposed by Arakawa and Schubert (1974). However, it employs three assumptions which significantly simplify the formulation and implementation of the scheme. It is assumed that an ensemble of convective-scale updrafts with as...
