Fig. 4: Simulated atmospheric responses to SST anomalies.
From: Antarctic Peninsula warm winters influenced by Tasman Sea temperatures
Geopotential height at 300 hPa (Z300) (m: shaded) with the horizontal component of wave-activity flux anomalies (m2/s2: vector) at 300 hPa (WAF300) from ref. 53 in (a) Globe–control experiment (CTL) difference, (b) ENSO–CTL difference and (c) TAS–CTL difference. For the CTL, climatological daily SST and sea ice cover data were used as lower boundary conditions. For each experiment (Globe, ENSO, and TAS experiment), the SST anomalies between warm and cold winters over each region (Globe: 90°S–90°N, 0–360°E, ENSO: 5°S–5°N, 170–260°E, TAS: 48–32°S, 160–180°E) superposed on the daily global climatology were used as forcing. Dotted areas denote significant differences exceeding the 95% confidence level.
