Description: Annual Mean Fraction Skill Score (FSS) measures the average skill of a model's forecasts during a given year. An annual mean FSS of 1 denotes excellent forecasts during a given year, and an annual mean FSS of 0 denotes very poor forecasts during a given year. FSS values for 24-h, 48-h, and 72-h forecasts are shown in red, green, and blue lines, respectively. An increase in FSS from left to right means that forecasts have improved over time.

Description: Annual Mean Equitable Threat Score (ETS) measures the skill of a model's forecasts relative to chance during a given year. The larger the value of the ETS is during a given year, the better a model's forecasts were relative to chance. ETS values for 24-h, 48-h, and 72-h forecasts are shown in red, green, and blue lines, respectively. An increase in ETS from left to right means that forecasts have improved over time.
