Study on the long-term variations of precipitation amount and temperature in northern Kanto District

Abstract

The rise of temperature by “greenhouse” effect attracts public attention. So far many papers on this problems have been presented, but the results are sometimes different from each others. Such differences are probably caused by data treatment. This paper intends to examine long term variations of temperature and precipitation amount in Kanto District, forcusing on the contrast between urban areas and rural districts, moreover between the Pacific side and the Japan sea side. The main results are as follows: the present state of temperature variations is in low-stage in rural districts and rising state in urban areas, and precipitation amount are decreasing at many observation points.
