MOREIRA, Janaína; AMORIM, Margarete  and  GARCIA, Felipe. Analysis of intensity and hourly evolution of the heat and dry islands in a tropical environment, Brazil. GOT [online]. 2019, n.17, pp.151-178. ISSN 2182-1267.  https://doi.org/10.17127/got/2019.17.007.

This paper aims to analyze the intensity and hourly evolution of heat and dry islands in Penápolis, a small city in the Northwest region of São Paulo State, Brazil, according to different synoptic conditions. Results indicated the formation of a urban heat island from 7pm to 9am, with maximum intensity of 3.5°C, and a dry island from 11pm to 9am, with maximum intensity of -9.4%. The heat and dry islands acted concomitantly in the urban area, especially during days with stable weather conditions (light winds and no precipitation). In addition, we emphasize that both islands showed maximum intensities in December (summer), which indicates an aggravating situation, once the thermal discomfort in the tropical environment in this season were potentialized by these phenomena.

Keywords : Urban climate; Urban heat island; Air temperature; Relative humidity.
