Regional Weather Modeling on Parallel Computers
نویسندگان
چکیده
This special issue on \Regional weather models" complements the Oc-tober 1995 special issue on \Climate and weather modeling", which fo-cused on global models. In this introduction we review the similarities and diierences between regional and global atmospheric models. Next, the structure of regional models is described and we consider how the basic algorithms applied in these models innuence the parallelization strategy. Finally, we give a brief overview of the eight articles in this issue and discuss some remaining challenges in the area of adopting regional weather models to parallel computers.

MM90: A Scalable Parallel Implementation of the Penn State/NCAR Mesoscale Model (MM5)
This paper describes MM90, a parallel regional weather model based on the Penn State/NCAR MM5. Parallelization of nite diierencing, horizontal interpolation, and nesting on distributed-memory (message-passing) computers is handled transparently using the RSL library package. Fortran90 modules, derived data types, dynamic memory allocation, pointers, and recursion are used, making the code modul...
