英文摘要
We observed wind velocity in the mesosphere and lower thermosphere (MLT) region at 70-110km altitude, by means of a meteor radar and two medium frequency (MF) radars that are operated in the tropics under international collaboration between Japan, Indonesia and Australia. Statistical analyses of the radar data clarified quasi-biennial and semi-annual oscillations in the zonal winds. The mean meridional flow showed a decadal scale trend, which could be related with the global warming and/or a solar cycle.
