SPACE AND TEMPORAL CHARACTERIZATION OF PRECIPITATION IN THE GREEN COAST - 2001 TO 2016

Abstract

The Green Coast, located in the southern part of the state of Rio de Janeiro, has been highlighted in the last decades by the tragedies that occurred as a consequence of intense rainfall events, such as in the years of 2002, 2009/2010 and 2013. The Serra do Mar mountains, very near to the ocean, is especially opposed to the displacement of the frontal systems, contributing to the high precipitation in this region. On the other hand, economic investments in road and port infrastructure and the reawakening of the naval industry at different times led many migrants to the region, establishing themselves in the few flat areas, and sometimes occupying steep slopes, especially in Angra dos Reis, one of the most densely populated cities in the Green Coast of Rio de Janeiro. Thus, using daily rainfall data from 12 meteorological stations present in Green Coast municipalities and neighbors in the state of São Paulo, tables and maps were constructed to understand the spatial and temporal distribution of precipitation in the area. The results showed that in Angra dos Reis the highest concentrations of rain are recorded, mainly in the Bracuhy and Mambucaba stations, where the population has been affected by floods and mass movements with material losses and lives.
