赤道地区平流层水汽准两年周期振荡特征

The QBO of Stratosphere Water Gas in Equator

采用了从1991-12月～2004-06时的卤素掩星试验(HALOE)资料,将其按季节在空间上进行了插值到5°×5°的经纬度网格上,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．分析表明：赤道地区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．

In this article, we use the data of HALOE from december 1994 to june 2004. The data is dealed with by embolic （5°×5°） in every season along the time, and then we calculate the average of the data, under this base, wo have calculated the dense of water, and draw it in time and hight in the equator. And then we have compared the result in our pictures with the O3 and the results of QBO. It says：at the area of equater there is an abverse sense of QBO. All the above-said, are very useful to the reseach work on the straitosphere and also its dynamic and chemic progress.
