Fig. 5: Simulated Arctic SIC responses to PNA changes.
From: Acceleration of western Arctic sea ice loss linked to the Pacific North American pattern
a Linear trend (% per decade) of SIC over the period 1979–2016. b SIC regressed onto the PNA index. c Time series of western Arctic SIC anomaly along with PNA index, lower-tropospheric temperature (T), specific humidity (SH), and downwelling longwave radiation (DLR). Shading with stippling indicates statistical significance at the 5% level in a and b.
