Fig. 4: SABB aerosol impact on precipitation evolution during the WAM season.

Time latitude Hovmoller diagram (covering May to November) of mean 2003-2015 daily SABB aerosol-induced precipitation anomalies (zonally averaged over 10°W−10°E) for: a the AERSLAB experiment which illustrates the effective impact of SABB aerosol on precipitation, b the AERFSST experiment which illustrates the feedback associated to SABB aerosol diabatic heating, and c the ANOSST experiment which illustrates the feedback associated to SABB aerosol-induced SST cooling.
