Density forecasts for weather variables are useful for the many industries exposed to weather risk. Weather ensemble predictions are generated from atmospheric models and consist of multiple future scenarios for a weather variable. The distribution of the scenarios can be used as a density...

Wind power forecasting techniques have received substantial attention recently due to the increasing penetration of wind energy in national power systems. While the initial focus has been on point forecasts, the need to quantify forecast uncertainty and communicate the risk of extreme ramp...

“We have become increasingly aware that our businesses and societies are embedded in complex systems – the economic system, the climate system, and so on – which are globally linked and may be susceptible to sudden change. Forecasting tools developed for the demands of classical astronomy...
