Abstract: 宇治川オープンラボラトリーの局地異常気象観測解析装置において大気境界層の観測を実施した。この場所は京都市市街地の近郊に位置する。測定された風について,平均風速はそれほど強くなく,風向は北西と南西方向から吹く風が多い特徴的な分布を示している。日変化については,大きな気象擾乱による影響をあまり受けていないと思われる場合,一日のうちの昼間午後に気温上昇と共に風速が強くなるという傾向が一年を通じて見られる。
Observations of atmospheric boundary layer have been made using the Observation and Analysis System for Local Unusual Weather in the Ujigawa Open Laboratory. This place is located in the suburbs of the Kyoto urban area. Measured mean wind speed is not so strong and the wind direction shows the characteristic distribution whose prevailing wind blows from the northwest and the southwest. In the weather with little effect of the large meteorological disturbances, diurnal variations of wind speed have a common tendency to increase with the rise of air temperature in the afternoon of the daytime all the year round.
