Statistically significant correlations at the 95% level are in bold shading. For WRF seasonal forecasts, an asterisk indicates that the result is statistically significant and better than the CFS reforecasts; bold indicates that the WRF seasonal forecasts are worse than the CFS reforecasts and statistical significance is retained; x indicates that the WRF seasonal forecasts are worse than the CFS reforecasts and statistical significance is lost.
