A NEW EVALUATION METHODOLOGY APPLICATION OF DRY SEVERITY FOR THE CITY OF CAMPINA GRANDE-PB
Droughts come from natural factors, and when they occur, cause changes in the climate, whether on a punctual or diffuse scale, and this cycle is constantly repeated, but in recent decades these impacts have increased with human actions from deforestation and burning of fossil fuels. Thus, the objective of this work is to employ a new application of the Drought Index methods (IAC, IPN and MD) to the data from the historical rainfall series of the municipality of Campina Grande - PB in the state of Paraíba, in order to classify the data on a monthly and annual scale, in order to identify the intensity over the years studied in this research. The pluviometric data used in the research correspond to the historical series from 1980 to 2019, which are divided into monthly precipitation data, provided by the Northeast Development Superintendence, National Institute of Meteorology and the Paraíba Water Management Executive Agency. The proposed methodology, in addition to the new standardization of the Drought Intensity Index (IIS), proposes a new characterization of the final rainfall condition or drought severity index. Finally, it allows environmental agencies and managers better conditions to adapt to problems related to drought and extreme rainfall, for greater management of water resources.
