Fig. 1: The relationship between Jun–Nov precipitation in Svalbard and atmospheric circulation features.
From: Climate extremes in Svalbard over the last two millennia are linked to atmospheric blocking
a Seasonal mean precipitation in Svalbard (PRSv; red rectangle in the inset) from June through November in two land-only observational datasets (see Methods): GPCC (solid black) and UDEL (dotted grey). Regression maps showing the relationship, for the period 1955–2019, between Jun-Nov monthly precipitation (GPCC PRSv) and (b) 500 hPa geopotential height (Z500) anomalies (colors) and winds (V500; arrows) from ERA5; (c) Sea surface temperature (SST) anomalies from HadISST dataset and (d) surface air temperature (SAT) anomalies from ERA5. Regression maps show changes for one standard deviation change in the monthly PRSv time series. Cross-hatching shows regions with significant regression coefficients at the 95% significance level.
