英文摘要: This work searches for the key elements separating the dynamic and quiescent phases characterizing the tropical atmosphere. The analysis is performed with satellite measurements that are composited into statistical time series individually for the isolated cumulus and organized system regimes. Free-tropospheric (FT) moisture convergence, cloud-base (CB) moisture updraft, and FT precipitation efficiency (FTPE) are then derived under large-scale moisture budget constraints. Precipitation is fed primarily by FT moisture convergence while FTPE and CB moisture updraft amplify in tandem as organized systems develop. In the isolated cumulus regime, FT moisture remains weakly diverging over time accompanying little change of FTPE. A thermodynamic budget consideration suggests that organized systems develop under a self-sustaining growth of large-scale updraft in the dynamic phase, while the quiescent phase is maintained by stable, shallow circulation accompanying isolated cumuli. © 2014.
