From: Skillful prediction of hot temperature extremes over the source region of ancient Silk Road
Correlation coefficients of spring soil temperature averaged over Central Asia in GLDAS-Noah and ERA-interim with summer hot days (HD) and heatwaves (HW) averaged over the SRASR (source region of ancient Silk Road) for the period of 1979-2016: (a) detrended time series, (b) inter-annual components of detrended time series; (c) inter-decadal components of detrended time series. Correlations of ±0.27, ±0.32 and ±0.41 indicate the 90%, 95% and 99% significance levels (the dash lines).
