Abstract

Abstract

Since 2000, in the support of two national key projects of "Chinese Heavy Rain Research Experiment" and "Research on Meteorological Numerical Prediction System Techniques", LaSW/CAMS has been in charge of developing new generation NWP system GRAPES (Global/Regional Assimilation and PrEdiction System). GRAPES' project is mainly focused on data assimilation, dynamical core, physical parameterization schemes, and infrastructure software. The main achievements include 3 dimensional variational data assimilation; standardized, modularized and parallelized coding infrastructure; full-compressible and non-hydrostatic meso-scale NWP system and its various applications. The operational results are highly encouraging and promoting for further developments. Also, a brief introduction to GRAPES research project, main progresses and some applications with future plan of GRAPES development is given.
- numerical weather prediction;
- data assimilation;
- global/regional multi-scale unified model
