THE ALGORITHMOF SOUNDING BALLOON FLOATING ERROR

With the development of numerical model, more attention is paid to the error caused by sounding balloon floating. In order to improve the quality of sounding data and reduce the sounding balloon drifting error, China Meteorological Administration puts forward an expansion code scheme. Based on the analysis of principal of current operational sounding system, the article introduces the algorithm of scheme, illustrates the utilization method and operational application prospect in terms of a case study。
