| 摘 要： | 利用MARMOT （Middle Atmosphere Remote Mobile Observatory in Tibet）激光雷达对2014年7月至12月格尔木（36.25°N，94.54°E）上空的中间层逆温层MIL （Mesosphere Inversion Layer）事件进行研究分析.格尔木MIL现象的发生频率为53.8%，其中冬季（12月）发生频率最高，达76%；秋季（9-10月）较高，为60%；夏季（7-8月）发生频率较低，为29%.2014年7月至12月观测到的MIL逆温幅度主要分布在5～20K，平均逆温幅度为15.9K.秋季逆温层底部高度较高，主要分布在77～84km，冬季和夏季逆温层底部高度较低，主要分布在64～74km.逆温层底部高度平均为75.1km.逆温层的平均宽度为8.7km，由夏季到冬季呈递增趋势.

| Abstract: | Based on the measurements of MARMOT (Middle Atmosphere Remote Mobile Observatory in Tibet) lidar located in Golmud, Qinghai (36.25°N, 94.54°E) from July to December 2014, Mesospheric Inversion Layer (MIL) over Golmud area has been analyzed. The average occurrence frequency of MIL over Golmud is 53.8% during this period. The occurrence frequency is highest and can be up to 76% in winter (December), is around 60% in autumn equinox, and is as low as 29% in summer (July, August). The amplitude of temperature inversion is within 5~20K, and the average value is 15.9K. The mean bottom altitude of MIL is 75.1km. The bottom altitude is higher and mainly from 77 to 84km in autumn. It is lower in winter and summer, and mainly from 64 to 74km. The mean width of MIL is 8.7km, and it increases from summer to winter. |
