Study on the Management for the Air Pollution in the Extensive Urban Area with the Vehicle traffic as its factor.

1)以东京周围的热岛为研究对象，考察了热岛的强度、分布或气象条件、年变化以及辐射环境和面积对日变化的影响。阐明了夜间辐射环境的热岛型特征和冬季辐射环境差的最大值。2)为了估算汽车交通对大气的余热或负荷量，估算了交通运输部门在各种燃料中的能耗，并用多种统计方法比较了其在世界上几个城市或地区的单位能耗或在各部门中的份额。3)为了弄清日本关东地区海陆风与氧化剂浓度分布的关系，利用1983年6~8月各大气污染观测点的逐时资料，对日本关东地区海陆风与污染面积的关系进行了调查。根据陆风的存在和海风的大小，将污染类型大致分为3种类型，根据海风形状将污染类型精确地划分为7种类型。此外，利用Suzuki-Kawamura(1987)的方法，讨论了天气压型与海陆风形状之间的关系，以及利用气象信息管理车辆交通的情景。

Simulation of the expansion of air pollution by vehicle traffic in the urban area was done and its management was discussed.1) Heat island around Tokyo was focused and its differences of diurnal change by its intensity, distribution or the meteorological condition, of annual change and by the radiative environment and its area were surveyed. The characters in the style of heat island by the radiative environment during the night and the maxium of the difference by the radiative environment in winter were clarified.2) To estimate the amount of the waste heat or of the load for the atmosphere by vehicle traffic the energy consumption in the transportation sector in each fuels was estimated and its unit energy consumption or share in all sectors were compared among several cities or regions in the world with several kinds of statistics. The regional variety of the energy consumption structure in the urban area or of the unit load for the atmosphere were clarified.3) To clarify the relationships between the land-sea breeze and the distribution of the concentration of oxidant in Kanto region, Japan the relationships between the land-sea breeze and polluted area was surveyed wiyh the hourly data of the observatory points for air pollution from June to August in 1983. Polluted pattern was roughly classified into 3 types by the existence of the land breeze and the scale of the sea breeze, and precisely into 7 types by the shape of the sea breeze. Additionally with the methods of Suzuki-Kawamura (1987), the relationships between the synoptic presure pattern and the shape of the land-sea breeze the scenario for the management of vehicle traffic by the meteorological information was discussed.
