                         occasionally propagate northwards at surface level, reaching the 
                         coastal tropical latitudes of Brazil and causing low temperatures, 
                         precipitation, and snow in high mountains. This paper presents an 
                         analysis of this south-north circulation (SNC) for the period of 
                         Jan/2004-Mar/2010, and shows how it determines extremes in monthly 
                         anomalies of average air temperature in south and southeast 
                         Brazil. Daily plots of NOAA-NCEP reanalysis for the vector wind at 
                         925 hPa were visually examined for the occurrence and extent of 
                         the SNC. On average, a reduction in the days with SNC per month, 
                         from about 8 to 1, is evident in the last six years; SNC is more 
                         frequent on May, June and July, and the maximum was 14 days of SNC 
                         on Jul/2004. Nine months showed peaks in the number of SNC days, 
                         when anomalies for surface air temperature in south Brazil varied 
                         from -1oC to -3.5oC. The summer of 2004, so far the season with 
                         more SNC, was the coldest on record for the last 45 years at Rio 
                         de Janeiro. On 20/Jun/2005, the SNC reached the latitude of ~15oS, 
                         thus propagating over more than 8,000 km from ~85oS.",
