Extended Data Fig. 2: Spatial Pearson correlations between instrumental summer EU JSL and climate variables in Europe for the period 1948–2018 ce.
From: Jet stream controls on European climate and agriculture since 1300 ce
Panels (a) and (b) show July-August 500 hPa geopotential height from the NCEP/NCAR dataset67; (c) and (d) show July-August temperature from the CRU ts4.05 dataset68; and (e) and (f) show July-August precipitation from the CRU ts4.05 dataset68, (g) and (h) show July-August self-calibrating Palmer Drought Severity Index68. Panels (a), (c), (e), and (g) show the correlations performed on raw data (both EU JSL and climate variables), whereas (b), (d), (f) and (h) show the correlations performed on linearly detrended instrumental July-August EU JSL and climate datasets. Colored composite maps are shown only where p ≤ 0.1 and areas with statistically significant values after controlling for the false discovery rate (αFDR ≤ 0.1) are cross-hatched.
