East/Southeast Brazil Forecasts Trend Wetter

ECMWF is most aggressive with the ongoing rains in Southeast/East Brazil. The outlook is supported by ongoing negative Antarctic oscillation (-AAO) which implies semi-permanent low-pressure troughs in the middle latitudes. ECMWF projects a semi-permanent low-pressure trough east of Argentina located across an area of relative cool SSTA. Meanwhile, east of Brazil, a marine heat wave (MHW) is expected to strengthen. The upper trough entrains increased low-level atmosphere moisture across the MHW driving a wetter Southeast/East Brazil climate likely to last through spring.
