Climatologia aplicada na análise de desastres urbanos: o caso do evento climático de Bodocó, Pernambuco, Brasil

Abstract

The study of climate is an important tool for understanding atmospheric phenomena that directly affect human life, such as the extremes of precipitation, temperature, relative humidity and climatic events, such as intense rains or long periods of drought in the Northeast region of Brazil. These events are responsible for strong socio-economic impacts on populations. In this context, the present work addresses a case study of the extreme climatic occurred in the municipality of Bodocó-PE in April 2018, where the city was flooded after heavy rainfall. Through the databases of the Pernambuco Water and Climate Agency, The Center for Weather Forecasting and Climate Studies, the Hydrography Center of the Brazilian Navy and the Brazilian Institute of Geography and Statistics, it was possible to perform the meteorological and statistical analysis of the event, using Excel software for descriptive statistical calculations through the following parameters: historical mean, median, standard deviation (SD) , variance, minimum and maximum value, amplitude and coefficient of variation of rainfall accumulated in April 2018. The results obtained demonstrate the irregularity and poor distribution of rainfall in the period under analysis, the forecasts of instability for the region on April 5 and 13 in 2018, as well as the impacts caused to the population where about 817 people were left homeless.
