Further investigation into the skillful water temperature predictions should aim to identify the extent to which performance is a consequence of thermal inertia (i.e., lead-in conditions). Options for modeling an outflow that varies with pressures. Moreover, seasonal forecasts for water temperature had higher performance in natural lakes than in reservoirs, which means human water control is a relevant factor affecting predictability, and the performance increases with water depth in all four case studies. Nevertheless, seasonal forecasts for discharge present some skill in all but one case study. We found that due to the limited predictability at seasonal time-scales over the locations of the four case studies (Europe and South of Australia), seasonal forecasts exhibited none to low performance (skill) for the atmospheric variables considered. We used the current seasonal climate forecast system (SEAS5) and reanalysis (ERA5) of the European Centre for Medium Range Weather Forecasts (ECMWF). Such flow conditions are exceptional and cavitation might occur on the crest profile. is larger than the design discharge coefficient (C. des, the pressures on the crest are less than atmospheric and the discharge coefficient C. Precisely, we analysed the historical performance using a data sample of past forecasts and reanalysis to obtain information about the skill (performance or quality) of the seasonal forecast system to predict particular events. ), the discharge coefficient tends to unity: that is, the broad-crested weir case. TRENBERTH National Center for Atmospheric Research, Boulder, Colorado (Manuscript received 22 March 2002, in nal form 12 July 2002) ABSTRACT Annual and monthly mean values of continental freshwater discharge into the oceans are. We assessed the performance of the resulting seasonal forecasts of discharge and water temperature by comparing them with hydrologic and lake (pseudo)observations (reanalysis). Estimates of Freshwater Discharge from Continents: Latitudinal and Seasonal Variations AIGUO DAI AND KEVIN E. The workflow has been designed to be applicable to any catchment and associated lake or reservoir, and is optimized in this study for four catchment-lake systems to help in their proactive management. In this paper, we introduce a feasible, robust, and open-source workflow integrating seasonal climate forecasts with hydrologic and lake models to generate seasonal forecasts of discharge and water temperature profiles. However, this link remains challenging for stakeholders and the water scientific community, mainly due to the probabilistic nature of these predictions. Obtaining seasonal forecasts for impact variables (e.g., discharge and water temperature) requires a link between seasonal climate forecasts and impact models simulating hydrology and lake hydrodynamics and thermal regimes. discharge of turbid sediment-laden water from a low-level outlet (like a sluice gate) while the surface waters remain clear or unchanged. This provides a potential resource to predict the influence of seasonal climate anomalies on surface water balance in catchments and hydro-thermodynamics in related water bodies (e.g., lakes or reservoirs). Seasonal climate forecasts produce probabilistic predictions of meteorological variables for subsequent months.
