Schematic diagram showing how the background subtropical gyres promote enhanced subtropical ocean warming and drives tropical expansion by shifting the position of meridional temperature gradients. (IMAGE)
Caption
Contours present the climatological oceanic barotropic stream function [69], which locates the major subtropical ocean gyres. On the right panel, the arrows illustrate the significant features of atmospheric (red) and upper oceanic (black) circulation. Under the forcing of increasing greenhouse gases, background subtropical ocean gyres promote enhanced subtropical ocean warming by converging the upper ocean water. The enhanced subtropical warming expands the low latitude warm water zones, pushes the mid-latitude MTGs toward higher latitudes, and thus forces tropical expansion. Figure modified from Yang et al. [10]. The National Oceanic and Atmospheric Administration OISSTv2 data [70] were used to calculate the linear SST trend. Please refer to the article for the references cited here.
