<b>Precipitação pluvial na bacia hidrográfica da Lagoa dos Patos, no período de 1964 a 2007 e suas associações com as safras de camarão-rosa</b>

Abstract

The abundance of post-larvae in the estuary depends directly on salinity, which is affected by the wind from the south face which facilitates the entry of marine waters in the estuary, and the flow caused by rainfall, which limits the entry of saline water. The rainfall in the basin of the Patos Lagoon is influenced by weather systems of different spatial and temporal scales. In this chapter we analyzed the rainfall catchment area of the Patos Lagoon for the period 1964 to 2007 . The 43 years studied were classified by Technical quantiles, as very dry, dry, normal, rainy and very rainy. By the same technique, the pink shrimp landings were also classified as very small, small, normal, high and very high.
