Fig. 7From: Narrow and wide India–Burma trough-like circulations: their different impacts on precipitation over southern ChinaComposite percentage (units: %) of winter precipitation anomalies for the years of (a) higher NIBT indices, (b) higher WIBT indices, and c both higher NIBT and WIBT indices. (d)–(f) as in (a–c) respectively, but for lower NIBT and WIBT indices. Green dots denote precipitation anomalies significant at the 99% confidence level. Note that there are no significant anomalies in (f) since there is only one year (i.e., 2009) with both NIBT and WIBT indices lower than − 0.75 standard deviationBack to article page
