Damped anomaly persistence
WebFinally, a damped anomaly persistence forecast attempts to combine persistence and climatology in such a way that it gradually transitions from the persisted to the climatological state, thereby optimizing the skill of the forecast at intermediate lead times (Van den … The squared term in Equation 1 is the local (Half) Brier Score (Brier, 1950).The SPS … WebApr 5, 2024 · The data allow the effects of droughts (and their persistence) on water storage, fluxes, and age dynamics in the CZ to be investigated (Smith et al., 2024).
