(a) Winter SSTAs (contours interval: 0.1 °C) regressed upon the simultaneous WIBT index. (b) Anomalous 700-hPa geopotential height (contours interval: 40, m2 s−2) and winds (units: m s−1) regressed upon the Niño 3.4 index in winter for the period 1979–2019. Shadings denote positive/negative SSTA anomalies and geopotential height significant at the 95% and 99% confidence levels as shown by the color bars. Anomalous winds significant at the 99% confidence level are highlighted in red. “A” in (b) denotes the anomalous anticyclone response to the ENSO-related forcing. The thick black contour denotes the Tibetan Plateau
