A method for evaluating sea-state by analysing GMS images

这项研究的目标是开发一个利用GMS图像、天气图和波浪图评估海况的系统。（1）利用GMS卫星的维斯和红外云图，结合专家的云系分析，建立了一种云系识别方法。通过引入模糊测度和模糊积分，可以对积云和层云系统进行区分和分类。(2)提出了一种从GMS云图上评估发展低压，例如台风的行为的方法。通过引入新的概念和定义，可以对权力和影响范围进行评估。(3)利用时间和空间相关性分析，提出了一种将天气图与海浪图进行相关的方法。利用天气图和海浪图之间的时间和空间关系，可以预测由于发展的低气压造成的严重海况条件/区域的实现。

The goal of the study is to develop a system for evaluating sea-state conditions using GMS images, weather charts and wave maps. To achieve the goal, following studies were carried out :(1) A method for discriminating cloud-system was developed using VIS and IR images from GMS with the assistance of neph-analysis by experienced experts. Cumulus and stratus systems can be discriminated and classified by introducing fuzzy measures and fuzzy integral.(2) A method proposed for evaluating the behavior of developed low, Typhoon, for example, from GMS cloud images. The power and area of influence can be evaluated by introducing new idea and definition.(3) A method for correlating the weather chart to the wave maps was developed using temporal and spatial correlation analysis. The realization of heavy sea-state condition/area due to developed low atmospheric pressure can be predicted using the temporal and spatial relations between weather charts and wave maps.
