Geometria urbana e ilha de calor noturna: análise baseada em um modelo numérico

Abstract

A geometria urbana é uma das causas do fenômeno da ilha de calor, pois provoca alteração do balanço energético nas cidades. Essa pesquisa visa identificar um raio de abrangência adequado para a determinação da influência térmica da geometria urbana. Para isso explora ferramentas de um Sistema de Informações Geográficas, aplicando um modelo numérico (o modelo de Oke), que relaciona a geometria urbana e a intensidade da ilha de calor. Dados térmicos reais são comparados a dados simulados para diferentes raios de abrangência. Os resultados apontaram que o raio de 30 m é o que em média permite maior aproximação entre dados reais e dados simulados. Além disso, verificou-se que o modelo aplicado demonstra comportamento diferenciado, conforme o grau de homogeneidade das alturas das edificações.
