A STUDY ON THE URBAN CLIMATE WITH DATA FROM THE METEOROLOGICAL OBSERVATORY IN THE NORTHERN AREA OF NAGANO PREFECTURE

摘要

In order to research the actual conditions of the urban climate in the northern area of Nagano Prefecture, certain weather data wee analyzed ,e.g.temperature ,globe temperature ,relative humidity, wind velocity, wind direction ,wet*. The area were divided to 500m meshes. Then, the weather data for each of the meshes were compared with the measurement data at the Nagano meteorological observatory. The authors obtained the following results: (1)All of the meteorological data (temperature, globe temperature ,relative humidity)are correlated with land use.(2)Differences were found between the weather data at the meterological observatory and the other areas: for example, the annual average temperamture at the other areas were higher than the data at the meteorological observatory; the value of this difference was about 1.5 deg C.
