Fig. 1: Surface anomalies of West Antarctica.
From: Antarctic Peninsula warm winters influenced by Tasman Sea temperatures
a Time series of averaged surface air temperature anomalies (°C, deviation from climatology for 1979–2019) during June to August at six Antarctic Peninsula stations (Bellingshausen, O’Higgins, Esperanza, Marambio, Vernadsky and Rothera). Red and blue dots indicate the top thirteen warm winters and twelve cold winters. Dashed lines show one-half standard deviation (±0.5σ). b Difference map of sea ice concentration (IC) (%: shaded) and ice drifting speed (ID) (m/s: vector) between warm and cold winters. Dotted areas denote significant differences exceeding the 95% confidence level.
