Spatial distribution and moisture recycling characteristics of persistent atmospheric basins (ABs) for each season (DJF, MAM, JJA, SON). Each AB for each season is labelled with a unique number, followed by its membership count in parentheses (indicating the number of years the AB was identified during the 40-year study period). The boxplots show evaporation (re, orange) and precipitation (rp, blue) recycling ratios for each numbered AB across the 40-year period, with boxes indicating interquartile ranges, median lines, and whiskers extending to the 5th and 95th percentiles. The horizontal dashed line at 50% indicates the threshold above which internal recycling dominates over external moisture exchange.
