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

As of today, however, there is no general consensus about whether there are, within CHs, preferential locations where the solar wind is accelerated. Knowledge of slow wind sources is far from complete as wel...
