Abstract

<abstract abstract-type="main" id="asl2493-abs-0001"> <title>Abstract</title> <p id="asl2493-para-0001">A new convective–stratiform rainfall separation scheme is developed through combination of rain types separated by surface rainfall budget using a cloud‐resolving model simulation data during TOGA COARE. Three rain types associated with vapor convergence, upward motions throughout the troposphere, and dominant liquid microphysical processes form convective rainfall. Maximum convective rainfall requires precipitation efficiency of 100%, but it is not associated with maximum vapor convergence. Vapor and hydrometeor convergences contribute about 40% to maximum rainfall, respectively. Four rain types associated largely with hydrometeor convergence, upward motions in the upper troposphere, and dominant ice microphysical processes form stratiform rainfall.</p> </abstract>
