Research on Tropopause Selection Method for High Altitude Sounding

Using upper-air sounding data since the use of the L-band-radar radiosonde at the Tacheng Na-tional Reference Station, based on tropopause meteorological data, this paper analyzes the characteristics and significance of tropopause, the determination of the tropopause, the selection method of the missing data in the part of tropopause, and the rational selection of several typical examples of tropopause in this station, and sums up the variation characteristics of tropopause, it provides a scientific basis for the study of weather and climate..
