都市気象学における先進技術のアジアメガシティーへの拡張適用

这项研究是基于一个新的研究领域的发展，称为“全球城市气候学”。这一概念所依据的假设是，城市地区不仅在地方一级，而且在区域一级对大气环境产生重大影响。它依赖于全球现有的各种气象和地理参数的数据集。首先，利用全球地面温度资料，获得了20世纪60年代至21世纪00年代的网格估算和台站观测的月地面气温资料。对1960年至1984年和1985年至2009年全球前30个特大城市的趋势进行了估计。比较了从台站估计的趋势和从更广泛的网格估计的趋势。温度增加速度快得多，在车站比在包括网格质疑网格估计的表面温度的代表性的程度。目前，正在将得出的趋势差异与能源消耗和风速和降水量等其他气象参数的趋势进行比较。

The research is based on the development of a new field of study called, “Global Urban Climatology”. The concept is based on the hypothesis that urban areas have a significant impact to the atmospheric environment not only in the local scale but in the regional scale as well. It relies on globally available datasets of various meteorological and geographical parameters. Firstly, using global surface temperature data from Berkeley Earth, grid-estimated and station-observed monthly surface air temperature data from the 1960s to 2000s was acquired. Trends were estimated for top 30 megacities world-wide for the years 1960 to 1984 and 1985 to 2009. The trends estimated from the stations and the trends estimated from the wider comprising grid were compared. Temperature was found to increase much faster in the stations than in the comprising grids questioning the extent of representativeness of grid-estimated surface temperature. Currently, the derived trend differences are being compared with energy consumption and trends of other meteorological parameters such as wind speed and precipitation.
