The WRF (Weather Research and Forecasting) model has been implemented at CIMA (Centro de Investigaciones del Mar y la Atmósfera) since November 2005, to provide operative short range, mesoscale weather forecasts over South America (http://wrf.cima.fcen.uba.ar). One of the most important aspects related to the utility of a forecast is the skill of the Quantitative Precipitation Forecast (QPF). QPF verification over South America is particularly difficult because of the lack of raingauge observations and the in-homogeneity of their location. This work discusses model performance against two different gridded data sets that have been used to assess the skill of WRF QPF using two alternative convective schemes.
