| 摘 要： | 利用ERA-Interim再分析资料,研究1979~2011年间平流层温度与平流层水汽的时空演变趋势。结果表明,平流层纬向平均温度场和平流层水汽的分布随高度、纬度、季节的变化而变化,且二者密切相关,互相影响。过去33a间在热带地区平流层温度均呈上升趋势,在南北半球,温度在平流层中下层呈下降趋势,而在平流层上层呈增温趋势。平流层水汽在不同层次、不同纬度带均呈增加趋势。平流层纬向温度在南北两半球的下降趋势与平流层水汽含量的增加趋势,进一步验证了全球气候正在变暖的事实。

| Abstract: | Based on the ERA-Interim reanalysis data,the distribution characters of the stratospheric zonal mean temperature and water vapor for 1979-2011 were studied. The results showed that the distribution characters of the stratospheric zonal mean temperature and water vapor varied with altitude,latitude and seasons,and closely related to each other. In the tropical,the zonal mean temperature had an increased trend,while in the northern and southern hemispheres it decreased in the lower stratosphere and increased in upper stratosphere in the past 33 years. The long-term trend of stratospheric water vapor had an increased trend in different altitude and latitude bands. The decreasing trend of the zonal mean temperature in two hemispheres and the increasing trend of stratospheric water vapor,further verified the fact that the global climate is warming. |
