Dynamical forecasting talks included IRI's calibrated subseasonal forecasts based on the Subseasonal Experiment (SubX; [8]) and calibrated seasonal forecasts based on the North American Multi-Model Experiment (NMME; [7]), which provide seamless prediction capabilities starting from 1 day to 6 months in advance. The low prediction skill of winter precipitation is attributed largely to model shortcomings in simulating the ENSO-independent, anomalous Pacific circulation, which is an important driver of year-to-year California precipitation variability. For drought preparedness, state and local water managers would like to rely on skillful forecasts on time scales that span the spectrum between weather forecasts and climate predictions.
