摘要: Abstract The two-dimensional version of the Goddard Cumulus Ensemble (GCE) model is used to simulate two South China Sea Monsoon Experiment (SCSMEX) convective periods [18–26 May (prior and during monsoon onset) 2–11 June (after onset monsoon) 1998]. Observed large-scale advective tendencies for potential temperature, water vapor mixing ratio, horizontal momentum are as main forcing in governing GCE a semiprognostic manner. SCSMEX case has stronger both temperature vapor, low-level vertical shear wind, larger available energy (CAPE). temporal variation model-simulated rainfall, time- domain-averaged heating, moisture budgets compares well those diagnostically determined from soundings. However, results have higher variability. underestimates rainfall by 17% 20% compared that based on model-simulat...
