             abstract = "Time series of sea level height of Santos (23o56.95'S 046o18.50'W, 
                         Brazil), during the period 1944 to 1990, were analyzed to 
                         determine seasonal and annual variability of storm surge activity. 
                         Astronomical tides were removed through the application of 
                         Thompsons filter and statistical detection of extreme events 
                         allowed the identification of data sets which were used to obtain 
                         composite fields of sea level pressure and surface winds over the 
                         Western South Atlantic based on NCEP/NCAR Reanalysis. The 
                         distribution of extreme events revealed autumn, winter, spring and 
                         summer, in this order, as the typical seasons for the occurrences 
                         - but not with large differences in amplitudes and frequency of 
                         the events. Positive anomalies of mean sea level were basically 
                         associated with spatial patterns of extra-tropical cyclones over 
                         the ocean and extra-tropical anti-cyclones over the continent. The 
                         opposite pattern, related to persistence of low pressure center 
                         over land and high pressure over the ocean, appeared associated 
                         with negative anomalies of mean sea level in Santos. These 
                         patterns were usually associated with different stages of the 
                         evolution of meteorological systems over the Western South 
                         Atlantic. In a general way, days of extreme storm surges in Santos 
                         are related with occurrences in southernmost stations one or two 
                         days before, due to meteorological activity of frontal systems and 
                         the correspondent cyclones and anti-cyclones persistence and 
                         propagation. On the other hand, sub-tropical cyclogenesis can play 
                         an important role for surges in Santos with small influence on 
                         southern stations..",
