Este trabalho teve como objetivo, estudar a frequencia do grau de risco de ocorrencia de queimada e de incendio e as medidas de prevencao, em Belem - PA, no ano de 2015, a fim de contribuir com os sistemas de alertas, na divulgacao do controle do fogo, pois causam custos e degradacao ambiental e sao fatores negativos para as sociedades. Foram utilizadas as temperaturas do ar, umidade relativa e a precipitacao, dados das 15: 00horas locais, obtidos no Instituto Nacional de Meteorologia. Os indices de predicao foram o Fator de Risco de Angstrom (FRA), Formula de Monte Alegre (FMA) e o Indice de Nesterov (IN). O clima de Belem-PA, no ano de 2015, mostrou que, o regime de temperatura do ar e estavel, o deficit de pressao do vapor d’agua apresenta conteudo significativo de vapor d’agua, a umidade do ar e elevada e a precipitacao pluviometrica nos tropicos assume papel preponderante. O indice FRA apresentou valores mais elevados quando comparados aos valores de FMA e IN, com resultados confluentes. Os modelos FMA e IN apresentam forte correlacao positiva e entre o indice FRA, boa correlacao positiva nos resultados. Belem–PA, com a falta de chuvas, apresenta valores mais elevados, nos graus de grande risco (GR) e de altissimo risco (ALR) e a prevencao e de fiscalizacao intensa e redobrada (FIR) e de estado de alerta (EA) e com a volta da estacao mais chuvosa, o risco de ocorrencia cai drasticamente, com as maiores frequencias nos graus de nenhum risco (NR) na regiao.

Were used air temperatures, relative humidity and precipitation data from the 15:00 local time, obtained from the National Institute of Meteorology. The prediction indexes used were: Angstrom Risk Factor (FRA), Monte Alegre Formula (FMA) and Nesterov Index (IN). The climate of Belem, in 2015, showed that the air temperature pattern is stable, the water vapor pressure deficit has a significant content of water vapor, high air humidity and the rainfall in the tropics takes leading role. The FRA index presented higher values compared to the values of FMA and IN, with confluent results. The FMA and IN models demonstrate consistent positive correlation, and between the FRA index, good positive correlation in the results. The city of Belem, with the lack of rain, shows higher values in degrees of high risk (GR) and very high risk (ALR) and the prevention measure is of intense and redoubled inspection (FIR) and alert condition (EA) and with the return of more rainy season, the risk drops dramatically with the highest frequencies in the degree of any risk (NR) in the region.
