An analysis of diabatic heating and moistening processes from 12 to 36 h lead time forecasts from 12 Global Circulation Models are presented as part of the “Vertical structure and physical processes of the Madden-Julian Oscillation (MJO)” project. A lead time of 12–36 h is chosen to constrain the large-scale dynamics and thermodynamics to be close to(More)
The role of convective processes in moistening the atmosphere during suppressed periods of the suppressed phase of a Madden-Julian Oscillation is investigated in cloud-resolving model (CRM) simulations, and the impact of moistening on the subsequent evolution of convection is assessed as part of a GCSS intercomparison project. The ability of Single Column(More)
A comparison of TWP-ICE observational data with cloud-resolving model results" (2012). NASA Publications. Paper 136. [1] Observations made during the TWP-ICE campaign are used to drive and evaluate thirteen cloud-resolving model simulations with periodic lateral boundary conditions. The simulations employ 2D and 3D dynamics, one-and two-moment microphysics,(More)
