| 摘 要： | 分析了1993年到2002年10年间HALOE卫星资料的热带平流层水汽年际变率，结果表明：热带平流层水汽混合比在2~5 hPa、10~30 hPa、30~100 hPa有三组显著的准两年周期振荡（QBO）现象；其中2~5 hPa和10~30 hPa水汽QBO呈反位相循环；30~100 hPa水汽QBO有显著上传特性.SOCRATES3模式模拟和诊断结果表明，热带平流层水汽QBO是在纬向风QBO强迫下产生的次级动力、热力因子和化学作用耦合后的结果：上层主要是环流输送引起，中层是环流输送和温度扰动驱动下的化学作用引起，下层是对流层顶水汽冻结层的温度扰动和环流输送引起.

| Abstract: | The Quasi-Biennial Oscillation (QBO), the most interannual variations of tropic stratospheric water vapor are investigated by the HALOE data from 1993 to 2002. There are three centers of water vapor QBO located in upper, middle and lower stratosphere respectively. The simulation results from model SOCRATES3 indicated that the QBO forcing of tropical zonal wind would induce three pairs of residual circulations, and the dynamic transports play an important role in the three QBO centers of water vapor. The QBO of temperature could control the chemical production of water vapor in the middle stratosphere. On the other hand, the temperature's QBO had an important effect on the water vapor condensation in the lower stratosphere. |
