Based on the systematic observations conducted from 2002 to 2003, the mean temperature characteristics and variation behaviors of the middle atmosphere temperature profiles over Wuhan are given.

Research on middle atmosphere including stratosphere and mesosphere has been an active area since 1970s for both atmospheric science and solar-terrestrial physics community, owing to its sig-nificance of understanding upper-lower atmosphere coupling and global climate and environment.

,et al,1987)) wind fields are important to study the chemistry and dynamics, especially the waves in middle atmosphere; likewise, wind fields are also very important parts of the wind mode.

The HALOE observational data from December 1991 to May 2004 are used to analyze the vertical and horizontal distributions of H2O and CH4 in the middle atmosphere,especially in the upper stratosphere and mesosphere.

The middle atmosphere, stretching from roughly 10 to 100km altitude, is a region of complex physical, photochemical and dynamic interaction.

But the lidar system can operate only at one kind of wavelength every time due to lack of laser equipment, so it can detect either the mesosphere of 30～80km or the sodium layer of 80～110km at a time and can t detect both simultaneously.
