Abstract
In this chapter, surface rainfall budget is analyzed using model domain-mean cloud-resolving simulation data of tropical rainfall event during TOGA COARE. The rain rate is mainly associated with water vapor convergence, while it is significantly modified by local changes of water vapor and cloud hydrometeor at a short time scale. The analysis of time- and domain-mean data shows that the rain rate corresponds mainly to surface evaporation flux and water vapor convergence, while local changes of water vapor and cloud hydrometeor have minor contributions to the rain rate. The mean rain rate comes mainly from convective rainfall regions, where cloud hydrometeor is transported into stratiform rainfall regions. Stratiform rain rate is mainly related to atmospheric drying. The surface rainfall budget is also applied to lag correlation analysis and the analysis of convective development at different stages.
