| Palavras-Chave | Enso modulation low-level moisture summertime meridional transport central South America | |||
| Resumo | The ENSO modulation during summertime -October through March- of the low-level meridional moisture flux across Central South America -CESA- is studied by means of El Niño -EN- and La Niña -LN- composites of the NCEP/NCAR reanalysis and EUA_CRU precipitation database during recent decades. The period October-March of EN events is characterized by positive precipitation anomalies over northern Argentina, most of Paraguay, Uruguay and the extreme south of Brazil, and a well-defined anomalous moisture influx into northern and central Argentina, more marked during November, December and March. In January there seems to be a bifurcation of the water vapor flux anomalies coming from the NW into northern CESA, which directs moisture towards the east, into central-east Brazil, and to the south into northern Argentina, the two places which show positive precipitation anomalies. In a regional context, the period is characterized by the enhancement of the climatological water vapor flux (except in October), i.e. inflow over the northeastern part of the continent, counterclockwise shift and southeastward extension up to the midlatitudes of South America. The largest anomalies appear over a NW-SE moisture corridor across CESA. Over the eastern side of the continent, at tropical latitudes, the anomalies are very small and only important, in comparison to those at equatorial latitudes, during January (reduced influx) and February and March (enhanced influx). Over the northern part of the continent there is a reduced water valor influx in every month except October. During the same period of LN events, the conditions over the southern half of CESA are opposite to those observed during EN (except for January and February). The situation is now characterized by precipitation deficit and southwesterly water vapor flux anomalies (i.e. reduced northeasterly moisture influx). Instead January, and to a lesser degree February, display positive precipitation anomalies similar to those observed during EN events. In particular, January presents the largest observed water vapor flux anomalies. Over eastern CESA there is enhanced NW-SE moisture influx in coincidence with large positive precipitation anomalies. In a regional context the period is characterized by reduced moisture influx over northeastern South America and to a lesser degree over the north, in particular from December through March. Thus, over northern South America the water vapor flux anomalies during EN and LN behave in an opposite way. Over the eastern side of the continent, at tropical latitudes, there is reduced moisture influx anomalies that combined with the enhancement of the northwesterly moisture corridor that crosses CESA, create a large low-level anticyclonic circulation anomaly. | |||
