摘要：

In this study, long term observations of medium frequency (MF) radar at Langfang site (39.4 degrees N, 116.7 degrees E) from 2009 to 2020 have been used to analyze the dependence of the 11-year solar cycle on horizontal winds in the local mesosphere and lower thermosphere (MLT). The results show that the zonal wind is positively correlated with solar activity during spring at 80-84 km, and during summer at 80-82 km; the meridional wind is positively correlated with solar activity during spring at 84-88 km and during summer at 84-90 km. In contrast, the results show no correlation between the horizontal wind and solar activity in autumn and winter. We attempt to explain the correlations in terms of the changes in stratospheric temperature and the net flux of gravity waves during solar activities. In addition, annual and semiannual oscillations of the zonal/meridional wind were found by using the least squares fitting method on daily horizontal winds, which show negative correlations with solar activity at heights of 80-90 km.
