CONTRIBUIÇÃO AOS ESTUDOS DO CLIMA URBANO: variação térmica e higrométrica em espaços intra-urbanos

Abstract

The objective of this work was to verify the existence of thermal variations and higrometrics in 4 points of collection in the urban area of Ipora-GO, these points if basically differentiated in the alone use and ocupation, had been collected given of temperature of air and relative humidity, in three schedules, to 9h (beginning of the heating), to 13h (bigger heating) and to 22h30 (beginning of the cooling) in two periods, the Þ rst one was from 28/04/2008 to 10/05/2008, as it was from 05/07/2008 to 14/07/2008. The 10 and of the monthly sinotic synthesis atmospheric systems had been veriÞ ed by means of satellite GOES that had acted in the days of the collection of data. The results had shown that in the two periods dry islands of heat and islands had occurred, as much in point 2 as in the 3, that they correspond to the places urbanizados. In May the biggest island of registered heat was of 2,8°C of intensity, and the biggest dry island was of 8%, both in day 02/05 in 3 point ace 9h. Already in July it was observed that these phenomena more intense, had had the presence of a dry air mass, being that in day 09/07 to 22h30 was veriÞ ed an island of heat in the magnitude of 3,2°C and a dry island of 22%. Key word: Urban climate, island of heat, dry island, Ipora.
