Extended Data Fig. 4: Accumulation of freshwater in the buffer zone influenced by wind conditions.
From: Arctic freshwater anomaly transiting to the North Atlantic delayed within a buffer zone
a, Sea level pressure (SLP) anomaly in 2019-2022 relative to the long-term mean of 1980-2022. b, SLP anomaly in 2019-2022 in case the perturbation shown in (c) is added, that is, (b) is obtained by adding (c) to (a) in the area indicated by the black circles. c, A negative SLP perturbation. The wind perturbation associated with this SLP perturbation (shown by arrows) is used in the perturbation simulation to reveal the impacts of winds on the ocean. d, Beaufort Gyre dye tracer at the end of 2022 in the historical control simulation, which corresponds to the atmospheric circulation condition in (a). e, The same as (d), but for the wind-perturbation simulation, which corresponds to the atmospheric circulation condition in (b).
