                         observed in Amazonia during 2005, as well as the main large-scale 
                         oceanic and atmospheric mechanisms associated are documented in 
                         this work. During rainy season (November 2004 to May 2005) and 
                         specially during dry season (June to September 2005), the spatial 
                         and temporal configuration of rainfall was very irregular with 
                         predominance of values below to very below of normal in most of 
                         Amazonian basin. The persistency of rainfall deficit was very 
                         accentuated particularly in western and southern Amazonia, 
                         including headboard regions of Solim{\~o}es, Negro, Juru{\'a}, 
                         Purus and Madeira rivers, which give significant contribution to 
                         fluvial regime of Amazon River Basin. During this period, the 
                         large-scale patterns were associated with a persistency of oceanic 
                         water warmer than normal covering most of the north basin of 
                         Atlantic and also in subtropical portion of south Atlantic Ocean. 
                         These persistent and anomalous patterns resulted in significant 
                         changes in South American meridional tropospheric circulation 
                         related to Hadley cell, so that a compensatory subsidence branch 
                         was verified over southern Amazonia, which inhibited strongly the 
                         development of tropical convection, explaining the drought 
                         condition in the region. Additionally, the configuration of 
                         episodes with anticyclonic circulation regime affecting the 
                         central and northeastern Brazil blocked meridional propagation of 
                         extratropical frontal systems into low latitudes of South America, 
                         which also contribute to below normal rainfall observed in 
                         Amazonia.",
