With the development of sounding instruments, various sounding data can be used by numerical weather prediction. The Local Analysis and Prediction System (LAPS) is introduced and localized for the better integration and assimilation of these various sounding data. The numerical experiment results show that the localization of LAPS is successful and LAPS can integrate T213 or NCEP, Doppler radar data, cloudderived wind data, sounding data, etc., to provide the direct mesoscale analysis fields to forecasters, and supply better initial fields to numerical models.
