| Abstract: | First,Storm Cell Identification and Tracking(SCIT) Algorithm in the Next Generation Weather Radar and storm algorithms in the SWIFT,including storm cell identification,storm tracking,storm forecast,are introduced.These storm products were applied in Guangzhou in 2008.For the SCIT product,the mean absolute errors for 30 and 60 minutes storm forecast are about 12.9 and 23.7 km,respectively.The storm samples are 5 124 and 2 203,respectively.With the increase of forecast length,the mean absolute errors of the s... |
