A typical deficiency of ensemble forecasts is the lack of calibration; e.g., ensemble members are under-dispersed and, consequently, probabilities estimated from them cannot be taken at their face values. Self-calibration is one of the unique theoret

To alert the public to the possibility of tornado (T), hail (H), or convective wind (C), the National Weather Service (NWS) issues watches (V) and warnings (W). There are severe thunderstorm watches (SV), tornado watches (TV), and particularly danger

Summary The ensemble Bayesian forecasting system (EBFS), whose theory was published in 2001, is developed for the purpose of quantifying the total uncertainty about a discrete-time, continuous-state, non-stationary stochastic process such as a time s

Two widely used precipitation analyses are the Climate Prediction Center (CPC) unified global daily gauge analysis and Stage IV analysis based on quantitative precipitation estimate with multisensor observations. The former is based on gauge records

Summary For quantification of predictive uncertainty at the forecast time t 0 , the future hydrograph is viewed as a discrete-time continuous-state stochastic process { H n : n = 1 , … , N } , where H n is the river stage at time instance t n > t 0

Summary Ensemble size requirements were analyzed using Bayesian ensemble forecasts ( Herr and Krzysztofowicz, 2010 ). These forecasts were generated using output from an analytic–numerical Bayesian forecasting system (BFS) within a Monte-Carlo algo

The novel research paradigm, dubbed the “court of miracles of hydrological modelling”, focuses on achieving scientific progress in circumstances which traditionally would be called model failures. Many of the associated modelling issues can be ad

A sequence of meteorological predictands of one kind (e.g., temperature) forms a discrete-time, continuous-state stochastic process, which typically is nonstationary and periodic (because of seasonality). Three contributions to the field of probabili
