Comparative analysis of the temperature and humidity in the urban and rural area of São José dos Campos (São Paulo, Brasil).

Abstract

It has been studíed through the comparative analysis of the contrasta of the temperature and humidity in the urban area and country of São José dos Campos (SP) Brasil. It was found significative effects of. the faces or slope (North, South, East and West) and the cover vegetation of the ground (forest, eucalyptus and grass) for the day time in meteorological sítuatíori by the control of the polar anticyclone, even though in the summer solstice (december - 1974). The measurements were effected in the period between december 2nd and 9th with psychrometers Asmann-Fuess, 80 cm from the ground. We found linear regressions between the data of the temperature and humidity obtained in the country area and those of the urban area resulting in the following equations:

Yl = 10,2263+ 0,5669Xl r = 0,83;
Y2 = 9,1507+ 0,6166X2 r = 0,86;
Ya = 42,37 + 0,4265Xa r = 0,45;

Where Yl and Y2 = temperature of the urban area; Xl and X2 temperature of the rural area; Y3 = humidity of the urban area and Xs = humldity of the rural area.

The results of the regression which refer to the data of humldity was not satisfactory. We analyse the meteorological situations that controll the weather during the fieldwork. Our results were compared with those published in the specialized climatological literature. Because of this experiment in the field the author proposes a series of projects or priorltaries approaches to the future researches.
