Advanced Numerical Methods for Numerical Weather Prediction
نویسنده
چکیده
The long term goal of this research is to explore new numerical methods for the next generation global atmospheric model. The reason for considering new methods is due to the paradigm shift in high performance computing from vector computers to distributed memory machines. To take full advantage of the new architectures the global domain must now be partitioned into subdomains/ elements that can then be solved independently on the multiple processors of a distributed memory machine. These new methods, along with the grids used to tile the sphere, must be local in nature to exploit the new architectures.

A synoptic-climatology approach to increase the skill of numerical weather predictions over Iran
Simplifications used in regional climate models decrease the accuracy of the regional climate models. To overcome this deficiency, usually a statistical technique of MOS is used to improve the skill of gridded outputs of the Numerical Weather Prediction (NWP) models. In this paper, an experimental synoptic-climatology based method has been used to calibrate, and decrease amount of errors in GFS...
