QPF verification using object-oriented methods to investigate the benefits of higher resolution models

摘要

Quantitative precipitation forecasts (QPF) from NWP models used at the European Centre for Medium-Range Weather Forecasts (ECMWF) are assessed using an object-oriented verification method, the SAL measure (Wernli et al 2008). This method provides quantitative and detailed information about different aspects of QPF, a complementary method to assess performance of high resolution models, which are usually penalized by classical scores.
