Abstract

The relation between local circulation and surface air temperature during mid-summer in Osaka plain was investigated with measurements obtained at surface layer and upper layer. As an index of sea breeze cooling, the amount of sensible heat advection was calculated by using a meteorological model. It was found that the plain area in Osaka is dominated by the sea breeze over 80% in the daytime on sunny days, so a promotion of the sea breeze introduction into the city area will be an effective countermeasures against the urban heat island problems in this area. The maximum air temperatures near the ground surface in land-sea breeze case and in westerly wind case are nearly identical, and both of these values are about 1 °C lower than that of in easterly case. The cooling rate shows the maximum value of 600 W/m2 when sea breeze has reached under the condition we investigated.
