摘    要:根据1979-2008年青藏高原地区14个探空站对流层项气压资料以及同期各标准等压面上的温度资料,分析了不同季节高原上空两类对流层顶高度与高空各层温度之间的关系;在此基础上,结合同期的NCEP/NCAR月平均再分析资料以及NASA提供的TOMS/SBUV月平均臭氧总量资料,分别讨论了高原上升运动以及高原臭氧总量与对流层顸高度的耦合关系。结果表明:高原第一(二)对流层顶高度全年处在300~200hPa(100hPa附近)高度,在季节变化、年际变化以及长期变化趋势上,两类对流层顸高度与各自对应高度层上的温度存在着密切的反相变化关系,当对流层顶高度偏高(低)时,相应高度上的温度偏低(高)。上升运动有助于两类对流层顶高度的抬升,尤其是当高空200(100)hPa附近有上升运动时,有利于第一(二)对流层项高度抬升。各季节高原臭氧总量与第二对流层顶高度均呈显著的负相关关系,当臭氧含量减少(增加)时,该对流层顶高度将偏高(偏低),近年来伴随着高原臭氧总量的减少,高原第二对流层顸高度出现了明显的抬升。

关 键 词:青藏高原  对流层项高度  季节变化  上升运动  臭氧总量

Abstract:Using tropopause pressure data and upper temperature data of 14 sounding stations over the Tibetan Plateau from 1979 to 2008, the relationships between two types of tropopause heights and upper air temperature in different seasons are analyzed. Based on these, the coupling connection between as-cending motion(total ozone) and tropopause height is discussed by monthly NCEP/NCAR reanalysis data from NOAA and monthly TOMS/SBUV total ozone data from NASA. The results indicate that the first(second) tropopause is at 300-200 hPa( near 100 hPa) over the year. The seasonal, interannual variations and long-term trend of the two types of tropopause heights display closely opposite relation to those of temperature at their corresponding altitudes, respectively, namely the higher(lower) tropopause height,the lower(higher) temperature at the corresponding altitude. The ascending motion is conducive to the rising of the tropopause height, especially the ascending motion at about 200 hPa( 100 hPa) is helpful to the rising of the first(second) tropopause height. There is an obvious negative correlation be-tween the total ozone and the second tropopause height at each season. The second tropopause rises (re-duces) with the losing(increasing) of total ozone over the Tibetan Plateau. In recent years, the second tropopause height clearly lifts with the reducing of the total ozone.
Keywords:Tibetan Plateau  tropopause height  seasonal variation  ascending motion  total ozone
