Studying the stability of the middle atmosphere (30-60 km) over Wuhan by Rayleigh lidar

摘要

The stability of the middle atmosphere ranging from 30 km to 60 km over Wuhan is elementarily studied, according to the observational data obtained in about one year through the WIPM Rayleigh lidar. The stability parameter (buoyancy frequency squared), which was obtained through the temperature field, shows that the middle atmosphere over Wuhan is stable all the year round, but the stability appears variable because the stability of summer and winter is lower, and that of spring and autumn is higher.
