It was developed a new method combined AMeDAS observation data with Meso-Scale Model (MSM) outputs for estimating difference in air temperature between AMeDAS point and estimation points. In my method it was applied the method of Ueyama, difference in air temperature is partitioned the difference between the estimation sites and the AMeDAS point : the influence of the radiative cooling intensity at the estimation site (T_<ESC>) and the influence of the radiative cooling intensity at the permanent observation site (T_<SSC>), and these components are modeled as a linear equation using a newly defined scale of radiative cooling intensity, the "radiative cooling scale (RCS)". In this study RCS values were computed using MSM outputs ; Grid Point Value (GPV), 5km grid upper air data computed using MSM and estimation models both of T_<SSC> and T_<ESC> were developed.

提出了一种将AMeDAS观测资料与中尺度模式（MSM）输出相结合的估算AMeDAS观测点与估算点之间温差的新方法。在我的方法中，采用了Ueyama方法，将估算站点与AMeDAS点之间的温差、估算站点（T_<ESC>）的辐射冷却强度的影响和永久观测站点（T_<SSC>）的辐射冷却强度的影响分割成一个线性方程，并使用新定义的辐射冷却强度尺度“辐射冷却尺度（RCS）”对这些分量进行建模。在本研究中，RCS值是使用MSM输出计算的；建立了网格点值（GPV）、MSM计算的5km网格高空数据以及T_<SSC>和T_<ESC>估算模型。
