VARIANCE CHARACTERISTICS OF TROPICAL RADIOSONDE WINDS USING A VECTOR-TENSOR METHOD




Parameter variations in prediction skill optimization at ECMWF

Algorithmic numerical weather prediction (NWP) skill optimization has been tested using the Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF).We report the results of initial experimentation using importance sampling based on model parameter estimation methodology targeted for ensemble prediction
