青藏高原对流层顶高度与臭氧总量及上升运动的耦合关系
Coupling relationship between tropopause height and total ozone as well as ascending motion over the Tibetan Plateau
摘要
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.关键词
