High resolution meteorological and chemical transport model was developed for the environmental assessment of regional air quality. In this study, at first, the Regional Atmospheric Modeling System (RAMS) was applied for 12 months continuous simulation over the Kyushu Region with 2 km horizontal resolution. Model results are intensively examined with the Japan Meteorological Agency routine observation data, and confirmed the high accuracy of metrological prediction. This annual scale (1 h interval) data set can be used as the database of virtual atmospheric dispersion experiment. Secondly, we made the on-line pollen dispersion model simulation over the Yamagata Basin with a multiple nesting technique to include the complex terrain effect in the air flow field. Model simulated pollen concentration was examined with the field observation, and show the high performance of model applicability. However, the pollen emission scheme is very uncertain and the establishment of such an pollen emission inventory controls the model accuracy. Finally we applied our approach to simulate the Asian scale yellow sand emission and transport. We made the three year 's spring time simulation between the year of 2000-2002, and the yellow sand concentration was examined with surface and lidar observation data. It was found that our on-line dispersion application was very much powerful to simulate the such a long-range transport of Asian yellow sand.

发展了一个高分辨率的气象和化学输送模式，用于区域空气质量的环境评价。在这项研究中，首先，区域大气模拟系统（RAMS）的12个月连续模拟九州地区的水平分辨率为2公里。模式的结果与日本气象厅的常规观测资料进行了深入的检验，证实了模式预报的高精度。该年尺度（1 h间隔）数据集可作为虚拟大气扩散实验的数据库。其次，我们利用多重嵌套技术对山形盆地的花粉扩散模式进行了在线模拟，以将复杂地形的影响纳入气流场。模型模拟的花粉浓度与田间观测结果进行了检验，表明模型具有较高的适用性。然而，花粉排放计划是非常不确定的，建立这样一个花粉排放清单控制模型的精度。最后，我们应用我们的方法来模拟亚洲尺度的黄沙排放和传输。对2000-2002年的3年春季进行了数值模拟，并结合地面和激光雷达观测资料对黄沙浓度进行了检验。结果发现，我们的在线分散应用程序是非常强大的模拟这样一个长距离的亚洲黄沙输送。
