The basic detection performance of four wind profiler radar sets of Beijing Meteorological Bureau is introduced. The application of newtype observation data in meteorological forecast service is discussed, with emphases on the secondary development of profiler data according to the atmospheric physics equations, taking two weather processes occurred on August 2009 as examples. In comparison with the base data of wind profiler, the redeveloped data derived from base data are more indicative in describing the occurrence and development of weather systems, can help improve the accuracy of shortterm weather forecasting and nowcasting.
