Fig. 1: Meiyu-Baiu rainfall in WIO cases, WIO-LSI cases, and WIO-noLSI cases.

Composite maps of CESM2LE-simulated precipitation anomalies [unit: mm/day] averaged from June to July for (a) WIO, (b) WIO-LSI, and (c) WIO-noLSI cases. The case number is shown in the parentheses. The stippling indicates statistical significance at the 5% level. Hereafter, the Meiyu-Baiu region is outlined by the black box (110°–140°E, 25°–35°N), and the Yangtze River is shown by the cyan line. The anomalies indicate deviations from 1981 to 2010 mean.
