Scatter plot of detrended hist-nat Northern Hemisphere 200-hPa jet latitude shift related to EEI against climatological 200-hPa hygropause latitude relative to the jet ( Methods ). The correlation is indicated (sample size = 16), along with the line of best fit (black) and the observed 200-hPa tropopause latitude relative to the jet (vertical grey line). Whiskers show 595% confidence intervals ( Methods ).
