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.

该项目的目的是阐明日本及其周围的对流层大气热分层的气候特征。这项研究涉及两个亚项目。第一个是热分层类型的区域分布，这些分布使用集群分析方法分类，使用该区域的气管观察站的数据进行分类。第二个是对流层热地层的研究，从气候气候的角度来看，科萨（黄色细尘）是示踪剂。前者的主要结果如下。研究中分类的气候区域对应于空气质量的分布，例如Alissow。日本的详细的情绪化划分是通过相同的方法进行的。每个气候区域都具有反转层频率分布的区域性和季节性的特征，可以通过盛行的空气质量来解释。后者的研究表明，KOSA是一种有用的示踪剂，可以观察大气中的热分层，这可以由Laser Radar肥胖。
