JAUE2018-086 Study on the effect of sea water temperature distribution pattern on sea breeze in Nagoya area

Abstract

Mitigation measures with sea breeze against urban heat island are effective in coastal cities. In the Nagoya region, it is known that sea breeze invades from the three bays and the Pacific Ocean, respectively. Because the sea water temperature distribution varies according to a day, the prediction of sea breeze cooling effect in Nagoya Metropolitan Area is very difficult. The purpose of this research is to aim for grasping the appearance of sea breeze by sea temperature distribution pattern.In this study, I used the sea surface temperature (SST) measured from satellite. In summer season, SST of Ise Bay, which is closest to Nagoya city, varied from 26 degree centigrade to 32 degree centigrade. I recognized four patterns of SST distribution around the region. Among them, I found that the sea breeze observed at the meteorological station in Nagoya tends to be weak on the day of higher sea temperature in Ise Bay in comparison with other bays and the Pacific Ocean.
