Observation of Sea Features and Weather Conditions on East China Sea, Yellow Sea and Bo-hai, and Its application

利用各种卫星数据，通过从空气、水和陆地区域采取的方法，取得了以下结果。东北亚陆上气象条件：利用时间序列卫星观测资料研究了东中国海、黄海和渤海的海况。它揭示了从冬初到春末水温的变化、海水的冻结模式和水锋的形成。从气候条件、腹地存在、港口容量和运输能力等方面对渤海地区的生产力情况进行了专门的调查。渤海、黄海和日本西部沿海地区的水污染情况：卫星观测首先在辽河、特东江和阿穆尔河河口段进行。为了评价水污染的严重程度，我们开发了一种基于模糊理论的新的分类方法，并将其应用于坎门地区的浊度评价，证明了该方法的有效性和有效性。目前正在利用该技术对上述地区进行浊度估算。东北亚地区空气污染与日本酸雨的关系：利用卫星数据确定排放污染物的地点，即酸雨的来源。进行了实验室实验，以获得与卫星数据的相关性。这项研究取得了部分成功，但仍在调查中。

The following results have been obtained through the approaches from air, water and terrestrial zones using various satellite data.1. Weather conditions on onshore areas in North-Eastern Asia: The sea features of the East China Sea, Yellow Sea and Bo-hai were investigated by the time series satellite observation. It revealed the change of water temperature, the freezing patterns of the sea water and the formation of the water front from early winter to late spring. The circumstances concerning the productivity on the Bo-hai area were specifically investigated in connection with weather conditions, existence of hinterlands, capacity of harbors and capability of transportations.2. Water pollution in the Bo-hai, Yellow Sea and the coastal areas in the West Japan: The observation using satellites was carried out first in the mouth parts of the Liao River, Tedong River and Amur River. With the aim of estimating the severity of water pollution, we have developed a new classification technique based on the Fussy theory which showed its validity and as well efficiency in application to the turbidity estimation on the Kanmon area. The turbidity estimation on the above-mentioned areas is under investigation using this technique.3. The correlation of the air pollution in the North-Eastern Asia and the acidic rain in Japan: Satellite data was used to identify the spots discharging pollutants, i.e., source materials of the acidic rain. The laboratory experiment was conducted to obtain the correlation with the satellite data. The study is partly successful but still under investigation.
