a Climatological mean distribution (shading, unit: ms−1) and the first EOF mode (contour, unit: ms−1) of zonal wind at 200 hPa from 1979–2016. b The regressed geopotential height at 500 hPa (contour, unit: gpm) and horizontal wind at 850 hPa (vector, unit: ms−1) distribution against the negative phase of JMDI. c The scatter plot between interannual EASRI and JMDI and their correlation coefficient (CC). The shading in the regressed geopotential height indicates the statistical significance at the 90% (0.9) confidence level evaluated by the Student’s t-test based on the effective number of degrees of freedom
