Western North Pacific Tropical Cyclone Reanalysis 2005-2008

Western North Pacific tropical cyclone reanalyzes, 36 individual datasets from 2005 to 2008 at 10km lat/lon moving grids.

36 tropical cyclones in the Western North Pacific were reanalyzed using a combination of TC dynamic initialization and WRF three-dimensional variational (3D-Var) assimilation method (TCDI/3DVar). The domain is 1500x1500 km and it is following the center of a given tropical cyclone based on Joint Typhoon Warning Center (JTWC) best track data. Temporal frequency of the data is 6 hours during a lifetime of a given tropical cyclone.

Please note that the lat/lon coordinates are relative to the tropical storm center ( lon=0. , lat=0.)  and not related to geodetic longitudes and latitudes.  The initial storm centers are listed in the supplemental info given below.

For more information regarding the reanalysis technique please, refer to the supplement document given below, or contact the originator Dr.Tim Li at
