Slingo}, title = {Assessment of ECMWF forecasts: widespread rainfall events during the Indian summer monsoon}, abstract = {The skill of dynamical forecasts of widespread rainfall events (WSREs) over central India is examined using high-resolution models from the European Centre for Medium Range Weather Forecasts (ECMWF). The WSREs entail interactions between the large-scale monsoon circulation and the convective systems which are embedded within the boreal summer Inter Tropical convergence zone (ITCZ). A diagnostic analysis of the ECMWF forecasts of WSREs during 2007 is performed. Several features of the observed rainfall distribution and large-scale organisation of convection during WSREs are found to be realistically captured by the ECMWF forecasts. The paper acknowledges a potential wider scope for diagnosing the influence of remote and regional forcings on the organisation of large-scale convection. The appraisal could be extended to break phases associated with the evolution of large-scale suppressed convection.}, year = {2009}, journal = {ECMWF Technical Memoranda}, number = {580}, pages = {19}, month = {01/2009}, publisher = {ECMWF}, url = {https://www.ecmwf.int/node/11307}, doi = {10.21957/691kj4uk}, language = {eng}, }
