| Abstract: | According to the tropopause height determined by the daily sounding data from 12 observational stations in the North China from 1979 to 2008,the occurrence of tropopauses of different types and their seasonal changes in height were analyzed in terms of methods of a linear trend,a wavelet analysis and an empirical orthogonal function(EOF).The results show that the first tropopause appears more frequently in winter than in summer.The frequency of occurrence for the first tropopause has a decreasing trend in r... |
