The purpose of this project is to clarify the climatological features of thermal stratification of tropospheric atmosphere over Japan and its surroundings. This study involves two sub-projects. The first one is regional distribution of the thermal stratification types which are classified by cluster analysis method using the data at Aerological Observation Stations in this area. The second one is the studies on thermal stratificaton in troposphere, revealed by Kosa (yellow fine dust) as a tracer from the view point of airmass climatology.The main results of the former study are as follows. The climatic regions classified in the study correspond to the distribution of airmass, for example, by Alissow. The detailed clematic division in Japan was made by the same method. Each climatic region has the characteristics on regionality and seasonality of the frequency distribution of inversion layers which can be explain by the effect of prevailing airmass.The latter study shows the Kosa is an useful tracer in order to observe the thermal stratification in atmosphere, which can be obeserved by laser radar.

本项目的目的是阐明日本及其周边地区对流层大气热层结的气候学特征。这项研究包括两个分项目。第一部分是热层结类型的区域分布，利用该地区的高空气象观测站资料，用聚类分析的方法对热层结类型进行了分类。第二部分是从气团气候学的角度，用黄尘作为示踪剂对对流层热分层进行了研究，主要结果如下：在研究中划分的气候区域对应于气团的分布，例如，由Alissow。用同样的方法对日本进行了详细的气候区划。各气候区逆温层频率分布具有明显的区域性和季节性特征，这可以用盛行气团的影响来解释，后者的研究表明，科萨是一种有用的示踪剂，可以用来观测激光雷达观测的大气热层结。
