摘要: Abstract Effects of momentum deposition due to solar diurnal and semi-diurnal tidal waves on the zonal mean circulation in mesosphere lower thermosphere for a solstice condition are discussed. In present model, system zonally averaged equations perturbation integrated simultaneously, so that propagation is affected not only by basic fields but also induced deposition. Results two different vertical eddy diffusion profiles presented. It shown tides make significant contribution generation winds upper thermosphere. Below 120 km main propagating tides, while above it semidiurnal tides.
