A method for evaluating sea-state by analysing GMS images

这项研究的目的是开发一个系统，利用全球卫星导航系统的图像、天气图和波浪图来评估海况。为了实现这一目标，开展了以下研究：①利用GMS的VIS和IR图像，结合经验丰富的专家进行nef分析，建立了一种判别云系统的方法。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判别和分类。(2)提出了一种利用GMS云图评价发达低气压（以台风为例）行为的方法。可以通过引入新的理念和定义来评估影响力和范围。(3)利用时空相关分析，建立了天气图与波浪图的关联方法。利用天气图和波浪图之间的时空关系，可以预测低气压发展导致的重海况/重海区的实现。

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.
