Análise da influência das ondas de calor ocorridas de agosto a novembro de 2023 sobre cidades do Pará.

Abstract

The high temperatures throughout 2023 in Brazil were a source of great concern for the population. Heat waves (HWs), commonly thought of as a prolonged period of hot weather and high humidity, were the cause of these temperature extremes. OCs do not have a well defined period and are difficult to characterize, as there is no specific meaning, and it is seen that similar meteorological situations can establish an OC in one place, but not in another. The objective of this work is to analyze, among the municipalities studied (Foz do Iguaçu, Marechal Cândido Rondon, Itaquiraí, Dourados, Campo Grande, Coxim, Sonora, Rondonópolis, Campo Verde, Nova Ubiratã, Sorriso, Sinop, Gurantã do Norte, Itaituba, Placas, Santarém), which was most affected by the heat waves that occurred between the months of August to November 2023, in addition to observing whether such waves affected the three municipalities of Pará. To this end, a calculation was made difference between the average temperature for the aforementioned month of the wave and the local maximum daily temperature, thus, the municipality that obtains 5°C above the monthly average will have the value for identifying a heat wave. The results demonstrated that Rondonópolis was the city that suffered most from extremes of heat. Among the cities of Pará, Itaituba and Placas were affected by a specific heat wave. Such r
