| 英文摘要 | Atmospheric gravity wave activities in the mesopause region have been observed and statistically investigated with a sodium lidar chain in eastern China. In total, there were 471 gravity waves identified from over 5400h of observations at Hainan (19.99 degrees N, 110.34 degrees E), Hefei (31.87 degrees N, 117.23 degrees E), and Beijing (40.47 degrees N, 115.97 degrees E). These waves typically had vertical wavelengths of (z)=2-4km, observed periods of T-ob=1-4h, amplitude growth factors of =-0.025 similar to+0.05km(-1), and wave amplitudes of Ae(*90km)=1.5-6%. Strong systematic parameter relationships were found, and they agree with the predictions of diffusive filtering theory. Statistical results show that the seasonal variability of gravity wave activity had a summer-maximum and winter-minimum characteristics in the mesopause region over eastern China. A qualitative interpretation is proposed regarding the seasonal and geographic variability observed by the lidar chain, based on analysis of source properties and influences from background wind, which vary by season. |
