| 초록 | The monthly average global tropopause pressure data in recent 57 a(from 1948 to 2004) is analyzed with EOF(empirical orthogonal function) method to discuss the spatial loading vector field and corresponding temporal variation.Then,the periods of tropopause pressure in every season are investigated by using wavelet analysis method.The results show that the decreasing trend of tropopause pressure in spring and summer is more distinct than that in autumn and winter in the most regions,and the corresponding tropopause height shows an increasing trend in spring and summer.It is distinct that the tropopause height might descend relative to the increase of tropopause pressure in East Asia and North America.The temporal variation of tropopause pressure in every season shows the multi-timescale feature.There is the significant period of 3~5 a in every season's tropopause pressure,also a quasi-biennial oscillation in spring. |
