METEOROLOGICAL OBSERVATION AND ANALYSIS USING 55M HEIGHT TOWER AT UJIGAWA HYDRAULIC LABORATORY-Diurnal and Annual Patterns of Wind and Vertical Temperature Distributions-

By 正昭 田中, 暢太郎 中島 and 英雄 多河

Abstract

Wind and vertical distribution of the temperature have been continuously observed fromApril 1976 using 55m height tower at Ujigawa Hydrauric Laboratory located in thesouthern part of the Kyoto Basin.The diurnal and annual patterns of the 10-days average wind speed at 50m height, airtemperature at 2m, 50m height and temperature differences between 50m and 25m height, between 25m and 2m height were revealed. The amplitude of the diurnal temperaturevariation decreased with height throughout the year. The peak of the diurnal temperaturevariation at 50m height lags about 1 hour behind at 2m height in winter, and about30min. In summer.Wind and vertical distribution of the temperature have been continuously observed fromApril 1976 using 55m height tower at Ujigawa Hydrauric Laboratory located in thesouthern part of the Kyoto Basin.The diurnal and annual patterns of the 10-days average wind speed at 50m height, airtemperature at 2m, 50m height and temperature differences between 50m and 25m height,between 25m and 2m height were revealed.
