Dinâmica da relação entre queimadas e chuvas em Teresina, em histórico de 19 anos

Abstract

Considering that ecotonal regions have different geoenvironmental behavior and given the importance of determining the most favorable period for burning –as it allows preventive actions by Organs responsible bodies –, this study aimed to characterize the dynamics of the relationship between fires and rainfall from 2002 to 2020 in the Teresina municipality, capital of the Piauí state. Thus, being in an area dependent on the seasonality of the rainfall regime, Teresina has the months from July to December –second semester –as the most critical in fire occurrences, as they are the driest months of the year and the vegetation is more susceptible to the occurrence of this event. Thus, in this period of the year (especially in September and October) its occurrence is much higher compared to other months. It is also of fundamental importance to monitor droughts to minimize their impact on the occurrence of fire outbreaks, given their association with drier years.
