Fig. 2: Regression of SAT on the TSAI during MAM.

T2M indicates the 2-m air temperature (unit: °C). Areas with values exceeding the 0.05 significance level are highlighted by black dots. Letters A, B, and C mark the centers of a wave-train-like SAT anomaly. The dashed box outlines the significant center of the East Asian SAT anomaly. The blue line denotes the boundary of the Tibetan Plateau topography with an elevation of 3000 m. “***” indicates a significance level exceeding 0.01.
