Oceanographic and Atmospheric Processes

The Pacific oceanographic phenomenon "EL Niño" is responsible, during some months, for very significant atmospheric circulation disturbances in the coasts of southern Equador and Northern Peru. Consequently, derangements of some natural mechanisms, directly or indirectly related to wind patterns, are produced along northeastern, southeastern or southern coasts of Brazil. During Holocene, "El Niño" - like disturbances with longer duration (some tens or even hundreds of years), have been recorded in some places of this country.
