标题:Índices de Detecção de Mudanças Climáticas Derivados da Precipitação Pluviométrica e das Temperaturas em Recife-PE (Detection Indexes Derived from Climate Change Rainfall and Temperatures in Recife-PE)
摘要:This study aims to determine the detection rates of climate change derived from rainfall and maximum and minimum temperatures in Recife, through the RClimdex software, with the purpose of investigate whether there were changes in the behavior of climatic elements analyzed. It used daily data of rainfall and temperatures (maximum and minimum) in the period 1961 to 2008 in Recife, assigned by INMET. The results derived from the precipitation did not show significant trends of reduction. On the other hand, was diagnosed with increasing frequency of extreme rainfall events from the 1980, with daily rainfall exceeding 100 mm. Compared to the temperatures associated with, all indicate positive trends, indicating an increase of the maximum and minimum temperatures around 1 °C in 47 years analyzed, with increased frequency of hot days and nights, it noted the increase in heat waves in the region . Although the results present changes in climate indices, these changes are not necessarily associated with global climate change, but mainly through the actions of anthropogenic modification of the space.
