Abstract

The aim of this work is to review pluviometric natural disasters which have occurred in Brazil, addressing not only the climatic phenomenon, but also the joining factors that cause them. The discussion about climate change has underestimated the importance of multidecadal variability that could revolutionize the way that long term climatology and plans are done. Urbanization has been recognized as a key component for the transformation of weather events into natural disasters. Historical development of Rio de Janeiro, São Paulo and Florianopolis has been considered to contextualize vulnerability conditions in which a large part of the Brazilian population lives. In fact, urban growth and sprawl occur without consideration of natural constraints of land surfaces and climate variability, increasing the vulnerability of much of the population.
