Fig. 5

Anomalous vertical (surface–600 hPa) integral water vapor fluxes (vector, kg m−1 s−1) and divergence (shading, 10–5 kg m−2 s−1) regressed upon the (a) NIBT and (b) WIBT indices in winter for the period 1979–2019. (c) and (d) as in (a) and (b), respectively, but for anomalous precipitation (units: mm). The black box in (a) denotes Southwest China (SC; 18–28 °N, 100–107 °E), and the black box in (b) and (d) denotes the SC-SEC region (20–27 °N, 105–123 °E). The two regions are used to calculate the time series of area-mean water vapor divergence in Fig. 6. Shadings denote positive/negative water vapor divergence and precipitation anomalies significant at the 95% and 99% confidence levels as shown by the color bars
