Coordinates Conversion Method Of Conservative Physical Parameters From Latitude-Longitude Coordinates System To Rotated Cubed-Sphere Coordinates System And Hardware Device Performing The Same

摘要

A method of converting coordinates of a physical quantity from a latitude-longitude coordinates system to a rotated cubed-sphere coordinates system is disclosed. The method is performed in a hardware device including a computation part and a memory. A plurality of latitude-longitude grid areas which overlap a cubed-sphere grid area is determined. An overlapping area between the cubed-sphere grid area and the latitude-longitude grid areas is computed.
