             abstract = "The dynamical characteristics of the mesosphere and lower 
                         thermosphere region (MLT) can be studied from the atmospheric 
                         fields, such as wind and temperature. In this study we have 
                         investigated the MLT wind response to solar maxima 23 and 24 and 
                         solar minima 23 at low latitude in the Southern Hemisphere. The 
                         database consists of wind measurements from the VHF meteor radar 
                         at Cachoeira Paulista (22.7░S, 45░W), which were obtained during 
                         the periods from March 1999 to July 2006, from September 2007 to 
                         October 2008 and from June 2012 to October 2014. The results have 
                         revealed a possible effect of the solar cycle upon zonal and the 
                         meridional wind behavior, in which the eastward winds from May to 
                         July below 90 km during 2000-2002 and 2012-2014 were weaker than 
                         during 2005-2008 interval, whereas above 90 km the westward winds 
                         were stronger for years of solar maximum than years of solar 
                         minimum. From correlation analysis, it is possible to see that 
                         during June for all altitudes, the solar activity may have 
                         contributed to weaken eastward winds below 90 km and enhance 
                         westward winds above 90 km during this period. The southward winds 
                         were more intense for period of May-August at altitudes below 90 
                         km during solar maximum years.",
