Study on the Distribution of Air Temperature in Summer Days of Satte, Saitama pref. and the Effect of Open Spaces on the Urban Climate

Abstract

This paper presents the result of the analysis about relationship between air temperature distribution and distribution of open spaces in Satte city, Saitama pref., Japan.
First the close investigation of the air temperature distribution has been made and the next step, the regression analysis between air temperature and the ratio of green coverage has made.
From the regression equations the cooling ratio of each open space elements was estimated.
The value of the cooling ratio, °C/(10% coverage) from the parallel linear regression equation are as follows; At noon (14h00m):-0.21±0.010°C/(10%: green coverage)
At night (22h00m):-0.15±0.006°C/(10%: green coverage)
At early morning (4h00m):-0.13±0.007°C/(10%: green coverage)
