From: Role of sea-ice initialization in climate predictability over the Weddell Sea
(a) Anomaly correlation coefficient (ACC; Persistence) of the observed sea-ice concentration (SIC) anomalies between Jun-Aug and Oct–Dec seasons. Statistically significant ACCs at 95% confidence level of a two-tailed Student’s t test are shaded. (b) ACC of the Oct–Dec mean SIC anomalies between the observation and the CTR reforecast results from September 1st. Positive ACCs which exceed persistence values in (a) and are statistically significant at 95% confidence level of a two-tailed Student’s t-test are shaded. (c) Same as in (b), but from the SIR reforecast results from September 1st. (d) Differences in the ACCs between the SIR and CTR reforecast results. The maps were generated using Grid Analysis and Display System (GrADS) Version 2.1.a3 (http://cola.gmu.edu/grads/downloads.php).
