Topographic-scale Climatological Mapping

本研究的目的是尝试利用市政数据、新建立的气象观测数据和地形（土地覆盖）信息编制地形尺度气候图。选择仙台（沿海地区）和东心（内陆地区）两个目标区，仙台区：利用市町村环境站和新建立的风观测资料，阐明了夏季无风日的海风和谷风分布及其对温度的影响。在西部山谷地区，有山谷风与沿海地区的海风几乎同时开始的情况，也有海风在1-2小时后到达的情况。东心地区：利用市町村的数据，明确了夏季无风日的山谷风分布。因此，山谷风沿着千川川是2个小时后，山谷风到山坡。对日最高气温和日最低气温进行了三种天气条件下的17个测站的海拔高度、森林和城市等土地覆盖比例的多元回归分析。结果表明，利用城市资料，建立少量的1年观测点，合理安排各种天气条件下的气候资料，制作地形尺度的气温分布或风系等气候图是完全可能的。

The purpose of the present study is to attempt to prepare the topographic-scale climatological maps, using the municipality data, new established meteorological observation data and landform (land cover) informations. Two objective districts are selected, one is Sendai (coastal area), the other is Toshin district (inland area).Sendai District: Sea breeze and valley wind distribution and their effects on temperature in summer calm days are clarified, using the data of municipality environmental stations and new established wind observations. In the western valley site, there are the case in which valley wind starts with sea breeze of coastal area almost simultaneously and the case in which the sea breeze reaches behind 1-2 hours.Toshin District: Valley wind distribution in summer calm days are clarified, using the data of municipalities data. As a result, valley wind along the Chikumagawa River is 2 hours behind the valley wind up to mountain slope. On daily maximum and daily minimum temperature, multiple regression analysis was done in three synoptic conditions, in respect of the altitude and the proportions of land cover such as forest and urban area of 17 stations. As a result, the mesh maps of air temperature distribution are completed.As a whole, it was shown that to make topographic-scales climatological maps such as temperature distribution or wind system was sufficiently possible, using the municipality data, establishing small number of observation site for 1 year and appropriately arranging the climatological data in the every synoptic conditions.
