                         equatorward propagation originating from winter mid-high 
                         latitudes, which can produce significant forcing and to influence

                         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.",
