赤道地区平流层水汽准两年周期振荡特征

QBO of Stratosphere Water Gas in Equator

对1991年12月-2004年6月时的卤素掩星试验(HALOE)资料,按季节在空间上进行插值(5°×5°),并求出其距平,由此给出赤道地区的平流层水汽的时间———高度剖面图,将上述图表与臭氧的QBO进行比较,并进行试探性分析发现:赤道地区的水汽在平流层的低层至中上层存在着明显的QBO现象。这些工作对我们研究平流层大气的动力过程、化学过程、辐射过程都是有意义的。

The data of HALOE from December 1994 to June 2004 is dealt with by embolic （ 5°×5°） in every season along the time, and the average of the data are calculated. On this basis, the density of water is calculated, and drawn in time and height in the equator. And the result in the pictures with the O3 is then compared with the results of QBOo The result shows： at the area of equator there is an obvious sense of QBO. All the work above is very useful to the research work on the stratosphere and also its dynamic and chemic process.
