The Effects of Explicit versus Parameterized Convection on the MJO in a Large-Domain High-Resolution Tropical Case Study. Part I: Characterization of Large-Scale Organization and Propagation
Publisher: American Meteorological Society
Abstract: igh-resolution simulations over a large tropical domain (~20°S?20°N, 42°E?180°) using both explicit and parameterized convection are analyzed and compared to observations during a 10-day case study of an active Madden?Julian ...
The Effects of Explicit versus Parameterized Convection on the MJO in a Large-Domain High-Resolution Tropical Case Study. Part II: Processes Leading to Differences in MJO Development
Publisher: American Meteorological Society
Abstract: igh-resolution simulations over a large tropical domain (~20°S?20°N, 42°E?180°) using both explicit and parameterized convection are analyzed and compared during a 10-day case study of an active Madden?Julian oscillation ...
Isolating the Effects of Moisture Entrainment on Convectively Coupled Equatorial Waves in an Aquaplanet GCM
Publisher: American Meteorological Society
Abstract: AbstractThe rate of humidity entrainment in the convective parameterization scheme in a general circulation model affects the simulation of convectively coupled waves. However, it is unclear whether this is caused directly ...
The Impact of Finer-Resolution Air–Sea Coupling on the Intraseasonal Oscillation of the Indian Monsoon
Publisher: American Meteorological Society
Abstract: newly assembled atmosphere?ocean coupled model, called HadKPP, is described and then used to determine the effects of subdaily air?sea coupling and fine near-surface ocean vertical resolution on the representation of the ...
The Role of the Cloud Radiative Effect in the Sensitivity of the Intertropical Convergence Zone to Convective Mixing
Publisher: American Meteorological Society
Abstract: AbstractStudies have shown that the location and structure of the simulated intertropical convergence zone (ITCZ) is sensitive to the treatment of sub-gridscale convection and cloud?radiation interactions. This sensitivity ...
The Implications of an Idealized Large-Scale Circulation for Mechanical Work Done by Tropical Convection
Publisher: American Meteorological Society
Abstract: AbstractA thermodynamic analysis is presented of an overturning circulation simulated by two cloud-resolving models, coupled by a weak temperature gradient parameterization. Taken together, they represent two separated ...
