Short-Period Variation of the Activity of Atmospheric Turbulence in the MLT Region over Langfang

In this paper, we investigate the activity of atmospheric turbulence in the MLT region and the relationship between the activity of atmospheric turbulence and atmospheric wave activity. We use data from the Langfang MF radar (39.4 degrees N, 116.7 degrees E) from July 2019 to June 2020 and NRLMSIS 2.0 to calculate the parameters of atmospheric wave activity and atmospheric turbulence energy dissipation rate (epsilon). Atmospheric e is modulated by different periods at different altitudes, and while there are 12 h and 24 h periods at all altitudes, the main period is different at different altitudes. A comparison of the epsilon with atmospheric tide activity shows that tides have an effect on epsilon, and the influence of tides on e may be different at different altitudes. The pattern of variation in e is similar to that of the atmospheric activity of the gravity wave, with both e and the atmospheric activity of the gravity wave showing significant semi-annual variation.
