Figure 6 Regression maps of 500 hPa geopotential height anomalies against the ASI and WHD anomalies during 1979-2008: a ASI and b WHD. The ASI index in a has been multiplied by -1.0 for convenient comparison. The linear trends of the indices and the geopotential height have been removed before the regression analysis. The white line indicated significant regression at 95% confidence level with Student#cod#x02019;s t -test.
