A ilha de calor e a umidade relativa em Aracaju-Sergipe (Brasil). Intensidade e comportamento intradiurno

Abstract: Este trabalho tem por objetivo analisar os contrastes topoclimáticos no espaço urbano e periurbano da cidade de Aracaju. Isto foi possível mediante o confronto dos dados de temperatura e umidade relativa entre as estações meteorológicas urbanas com a estação meteorológica de caráter mais periurbano. As frequências relativas de ocorrência de diferenças de temperatura máxima maiores que zero (%>0), superaram os 96% no centro cidade e com frequências de 100% durante os finais da manhã até parte da noite.

“…Recent results confirm the tendency found in previous studies [10][11][12]: in Aracaju local climates are indeed influenced by urban morphology, natural ventilation, and proximity to water bodies. The combination of these features forms three well-defined local climates in Aracaju.…”

“…By using daily data between 2004 and 2012, Lopes et al [3] and Alcoforado et al [4] reported that low wind speeds were not associated with the highest Lisbon UHI intensities. In Aracaju, using the approaches discussed above, some studies pointed to higher heating in the central areas (up to 7.5 • C) in relation to the peri-urban areas and green spaces, which suggests that UHI intensities are equally significant [10][11][12]. Anjos and Lopes [13] used a mesoscale climatological network (2 year daily data) to report that UHI intensities (both daytime and nighttime) in Aracaju were not significant (average of 0.5 • C) reflecting the prevalence of low intensities (thermal difference up to 2 • C) whose frequencies exceeded 85% annually thus refuting the trend found in previous studies.…”
