From: Role of sea-ice initialization in climate predictability over the Weddell Sea
(a) Composite anomalies of the observed sea-ice concentration (SIC, color and contour in %) during Oct–Dec of lower-than-normal Weddell sea-ice years (1996, 1998, 1999, 2001, and 2010). Anomalies statistically significant at 95% confidence level using a two-tailed Student’s t-test are shaded. (b) Same as in (a), but for the CTR reforecast results from September 1st. (c) Same as in (b), but for the SIR reforecast results from September 1st. (d) Same as in (b), but for differences in the anomalies between the SIR and CTR reforecast results. Anomaly differences statistically significant at 95% confidence level using a two-tailed Student’s t-test are shaded. The maps were generated using Grid Analysis and Display System (GrADS) Version 2.1.a3 (http://cola.gmu.edu/grads/downloads.php).
