• Figure 6. A schematic illustrating the distinct characteristics of and the interplay between the fast component of aerosol emission reduction and the slow component of aerosol emission increase. Shadings represent anomalous oceanic potential temperature. Arrows in the two vertical planes are the anomalous cross-equatorial Hadley Cell and the anomalous oceanic STC. The thick arrows in the Top panel A illustrates intensified trades and the thin blue arrows illustrate the associated air-sea fluxes. The thick arrows in the Bottom panel B illustrate how the intensified STC induces cold water, which converges in west Pacific subtropics and upwells in the east.
