其上是平流层顶。
臭气层就位于平流层顶，它可保护地球不受危险紫外线的辐射。
In the stratopause lies the ozone layer, which protects the earth from the SUNS dangerous UV radiation.
结果表明：高原上空h 2o混合比在对流层上层随高度迅速减少，在对流层顶和平流层底达到极小值，平流层里水汽混合比随高度增加。
The results show that the H2O mixing ratio decreases with height in upper troposphere quickly reaches a minimum near the tropopause and the bottom of stratosphere; and then it increases.
对我国1980 ~ 2007年120个观测站的探空资料进行处理后，分别计算得出对流层顶高度、对流层温度和平流层低层温度。
Based on sounding data of 120 meteorological observation stations in China from 1980 to 2007, the height of tropopause, tropospheric temperature and temperature at low stratosphere were calculated.
从平均对流层顶高度的年变化看来，对流层顶高度与平流层低层温度呈负相关，与对流层温度呈正相关，且存在季节差异。
From annual change of the tropopause height, it was negatively related to lower stratospheric temperature and positively associated with the troposphere temperature, and there was seasonal difference.
