a Troposphere (300–1000 hPa) integrated WV radiative feedback (W m–2 K–1) computed by removing WV sourced from each region using the top-of-atmosphere (TOA) ERA5 radiative kernel approach (a) “Methods”. Numbers (1–54) indicate the source region number or tag. Shading corresponds to the magnitude of the JJA Arctic WV radiative response (W m–2 K–1) on the left side of the color bar and the relative contribution (% of total) on the right of the color bar. b Vertical structure of Arctic (70–90°N) WV radiative (W m–2 K–1), computed by removing WV from each tagged source region (x-axis) (b). Region numbers on x-axis in (b) correspond to numbered labels in (a).
