Correlation coefficients and the Brier-based score skill in parentheses between climate predictors and zooplankton biomass as used in the previously performed downscaling experiment (Dippner et al. 2000)

	BSE (1960–1992)	COADS-SST (1960–1992)
Acar (S1/M2)	0.70 (0.37)	0.70 (0.37)
Bos (S2/M7)	ns	ns
Evad (S1/M2)	0.80 (0.55)	0.78 (0.60)
Syn (S1/M3)	0.75 (0.32)	0.76 (0.50)
Temo (S1/M2)	0.64 (0.27)	0.71 (0.42)

The fitting period is 1960–1992. Acartia spp. (Acar), Bosmina longispina (Bos), Evadne nordmanni (Evad), Syncheata spp. (Syn) and Temora longicornis (Temo) as predictands. The season is denoted with an “S” and the season number, with S1 as spring (May values) and S2 as summer (August values). The month of the predictor is denoted with an “M” and the number. Bold numbers mark significant correlations with respect to the 99.9 % confidence level for the correlation coefficient and for the 99 % confidence level for the skill

ns no significance
