Multi-model ensemble of QPF in NMC/CMA

摘要

For the use of numerous NWP data in QPF,the major challenge is how to use them in the limited time and how to improve the forecast efficiency and accuracy.Short range ensemble forecas-ting (SREF) of quantitative precipitation (Du J,1997,Stensrud D J,2000,Du J,2002) can increase the forecast accuracy.In order to obtain the QPF products,multi-model rainfall ensemble forecast based on different rainfall models was developed in NMC/CMA.
