Abstract

Simultaneous observations with a sodium lidar in Wuhan, China (30.53°N, 114.37°E) and an MF radar in Yamagawa, Japan (31.20°N, 130.62°E) were conduced during the PREASA-2 campaign from Feb. 22 to March 15, 1996. Some observation results are given. The gravity wave induced velocities measured by both techniques are estimated to compare the gravity wave activities between the places with same latitudes and different longitudes. We found that RMS velocities in Yamagawa were larger than those in Wuhan, which suggest different gravity wave activities between the two places.
