Gao, F. Ping, X. Cui, X. Li] Summary: The relationship between surface rainfall rate and sea-surface temperature (SST) over tropical cloudy areas is revisited, and associated air-sea interaction processes are investigated based on hourly grid simulation data over cloudy areas from a two-dimensional coupled ocean-cloud resolving atmosphere model. A cloud-weighted data analysis shows that surface evaporation flux decreases with increasing SST and is one order of magnitude smaller than the residual between moisture convergence and condensation, playing a negligible role in moisture budget. Moisture convergence determines the surface rainfall rate by determining vapor condensation and deposition rates. Ocean mixed-layer thermal budget shows that the atmospheric surface flux is a major process responsible for SST variation while thermal advection and thermal entrainment play a secondary role. The results indicate that atmospheric impacts on the ocean are important whereas oceanic impacts on the atmosphere are not, in the tropical air-sea system, on short timescales. Thus, the relationship between surface rainfall rate and SST over tropical cloudy areas is not physically important. Further estimates indicate that the surface evaporation flux and residual between moisture convergence and condensation could have the same order of magnitude in daily-mean moisture budget.
