AbstractDuring Sudden Stratospheric Warming (SSW) at high latitude on northern hemisphere, planetary waves show upward as well as equatorward propagation originating from winter mid-high latitudes, which can produce significant forcing and to influence the mesosphere and lower thermosphere (MLT) tropical dynamics being able to reach low latitudes in the southern hemisphere. In this study, we have investigated the meteor winds and planetary waves behavior at Sao Joao do Cariri (7.4◦S, 36.5◦W) and Cachoeira Paulista (22.7◦S, 45.0◦W), Brazil, during Arctic SSW events. The behavior of MLT winds over both sites is characterized by a westward change rate in mid-January, but this change rate is increased during a SSW major in the winter hemisphere, mainly at Sao Joao do Cariri. These results point out a possible relationship between meteor zonal wind at low latitudes and zonal wind and temperature at 10 hPa in the northern polar region. These relationships have been interpreted as due to planetary waves breaking, which showed upward as well as equatorward propagation originated from mid-high latitudes. It can produce significant forcing and can also change the tropical MLT dynamics in lower latitudes of the southern hemisphere.
