摘要

For the purpose of recognizing the degree of the influence by sea breeze to air tempera-ture, observation instruments have been installed in 4 steel towers where the distancefrom the shore is different, and air temperature, wind direction and velocity, solar radia-tion, etc. were observed. Each observation instrument is installed in the south side of thesteel tower, for reducing the influence of steel tower in itself for land and sea breeze ofthe East-West directions that are the main direction in this region in summer season.Observed data are collected by wireless communication with the ground level. Potentialtemperature rise in both upper and surface air is restrained by influence of sea breeze atNanko which is located neighbourhood of the shore. When sea breeze blows, air tem-perature differences between the neighbourhood of shore and the other inland observa-tion points are around 2 - 4 K. And wind velocity at the neighbourhood of shore is about2 - 3 m/s larger than those at the other inland observation points. The maximum windvelocity occurs at around 17:00 in the evening at all observation points. The tendency tobe late at Suburb more than one hour from Coastal is confirmed from cross-correlationresults between coastal and other points. Urban which is located in midway is late abouthalf hour.
