Influence of Surrounding Physical Characteristics of Street Space on Temperature in Coastal and High-rise Urban Area

臨海部中高層市街地の街路における周辺物的特性が地上付近の気温分布に与える影響

In recent years, outdoor thermal environment seems not to be so good because of urban heat island phenomena and global warming. Especially, the mitigation of high temperature in high-rise urban area is needed. Therefore, for proposing the mitigation, this study aims at analyzing the effect of urban form on temperature distribution using observed data in two coastal urban areas in Yokohama (Minatomirai-21 area and Kannai area). The cooling effects of the sea breeze are expected as the resource for the mitigation in coastal areas. Accordingly, the effects of two types of sea breeze are found in the analyses.本研究では、横浜市沿岸部に位置する2つの中高層市街地を対象に、気温の同時多点長期実測調査を行い、気温分布の形成要因について、市街地形態に着目して分析を行った。その結果、得られた主な知見を以下に記す。(1)対象地の海風の1日の吹き方には、パターンA「終日南西方向からの海風が吹く日」、パターンB「海陸風循環が見られる日」、パターンC「南西方向からの海風が吹かない日」の3パターンが存在する。(2)東風については、水平方向の移流による影響が大きい。そのため、東風時は街路方向により気温分布が異なり、直交街路の気温が低い。(3)南西風については、鉛直方向の移流による影響が大きい。そのため、南西風時は市街地密度や建物高さばらつきにより気温分布が異なり、MM21の方が低温となる。
