Precipitation Biweekly Hindcast Skill

Subseasonal skill score based on the historical performance of each calibrated SubX model and their 3-model ensemble.

Skill is mapped by calendar month. The forecasts lead times are combined over the weeks 2-3 and the weeks 3-4 from the forecast start time (i.e., 14-day long periods respectively 9 to 22 days and 16 to 29 days after the forecast is issued). Forecasts skill scores combine start times by calendar month and across years 1999 to 2016.

These skill scores diagnostics maps give a sense of where and when (issued which months of the year and for which weekly lead times) subseasonal forecasts may have the potential to provide useful information.
