Icosahedral–Hexagonal Grids in Weather Prediction
From Wikipedia, the free encyclopedia
Icosahedral–Hexagonal Grids in Weather Prediction is a new approach to weather prediction which uses geodesic grids generated from an icosahedron and could become an attractive alternative to current climate models.
The original works of the use of the icosahedral grid in the geophysical problem date back to Williamson (1968) and Sadourny et al. (1968). These works were followed by (Williamson, 1969; Cullen, 1974; Cullen and Hall, 1979; Masuda and Ohnishi, 1986). In the 1990s, several research groups have developed icosahedral gridpoint General circulation models using their own new techniques such as, GME of Deutscher Wetterdienst for the numerical prediction model (Majewski et al., 2002)., ICON GCM: ICOsahedral Non-hydrostatic General Circulation Model joint project between Max Planck Institute for Meteorology (MPI-M) and the Deutscher Wetterdienst (DWD), CSU AGCM (Atmospheric General Circulation Model) at Colorado State University (Heikes and Randall 1995a, b; Randall et al., 2000, Randall et al., 2002; Ringler et al.,2000) and Nonhydrostatic Icosahedral Atmospheric model of Frontier Research Center for Global Change (Tomita et. al., 2001,2002; Tomita and Satoh, 2004).
