| 摘 要： | 为了解平流层大气温度变化规律,利用瑞利-拉曼-米散射激光雷达对南京上空平流层温度进行长期观测,对观测数据的分析表明:夜晚平流层温度受到重力波的影响,重力波破碎会导致局部温度升高,温度相对变化可以达到12%;在季节变化的过渡月份(4月和10月),平流层中低层温度会有所升高,对应的平流层高层温度降低;平流层温度月变化方面,除局部由于行星星际波的影响外,各月份平流层温度整体上相对比较稳定,激光雷达所测大气温度与大气模式温度具有一定的差别。最后,利用平流层温度廓线提取了重力波信息。

| Abstract: | Long-term observation of stratospheric temperature was conducted using Rayleigh lidar, in order to understand variation regularities of the stratospheric temperature. The analysis results of the observation dataset show that, the tratospheric temperature was affected by gravity wave, the breakdown of gravity wave led to temperature increasing, and the scope of variation was about 12%; temperature increased in lower stratosphere and decreased in upper stratosphere during April and October; in the aspect of inter-monthly variation, stratospheric temperature was relatively stable except the influence of the planetary wave, and there were differences between Rayleigh result and the model. Furthermore, the information of gravity wave was retrieved from the temperature profile. |
