COMPARAÇÃO CLIMÁTICA DE SÃO JOSÉ DOS CAMPOS, PARAIBUNA E SÃO LUIZ DO PARAITINGA ENTRE 1940-1970

The use, control and monitoring of water resources each year are becoming more detailed and important for the maintenance and protection of the basins that supply the industry, population and agriculture. The macro- and micro-scale geographic and environmental characteristics are decisive for the microclimate and water availability. To classify the microclimate and water balance, the Thornthwaite method was used for the cities of the Vale do Paraíba Paulista: Paraibuna, São José dos Campos and São Luiz do Paraitinga, with the input of data from 1940 to 1970. The studied municipalities are geographically close, and analyzing land use and occupation, as well as IBGE data, we found their characteristics that differentiate the climate of the municipalities, the anthropogenic interference in areas of the municipality destined to urban and population growth, forest vegetation and the construction of the Paraibuna/Paraitinga dam. The aim of this work is to classify and indicate possible alterations in the microclimate of each municipality, showing that humid microclimates were found, but with different subclassifications, and that the use and occupation of the soil increase some natural characteristics, such as temperature and water storage.
