雾在许多生态方面起着重要作用，它以各种方式影响着人类的生活。在这项研究中，对欧洲雾发生的变化进行了时间高度分辨率和空间明确的分析，并调查了与一般天气条件的联系。为此，研制了基于气象卫星第二代数据的高分辨率雾产品。通过对数据集应用自组织映射方法来识别特征雾分布。结果表明，雾型主要由地形特征决定。分析了这些模式与主要一般天气状况之间同时发生的情况。结果表明，一般天气情况可分为三大类，每一类负责形成不同的雾型。此外，在日雾频率周期和年雾频率周期中可以识别出明显的区域差异，并利用导出的区域特定频率变化来得出这些区域普遍存在的雾类型的结论。
Fog plays a major role in many ecological aspects and it influences human life in various ways. In this study, a temporally highly resolved and spatially explicit analysis of variations in fog occurrence was conducted for Europe and links to general weather conditions were investigated. To this end, a high‐resolution fog product based on Meteosat Second Generation data was developed. Characteristic fog distributions were identified by applying a Self Organizing Map approach to the dataset. It was found that the resulting fog patterns are primarily determined by terrain characteristics. Simultaneous occurrences between these patterns and the predominant general weather situations were analyzed. The results show that the general weather situations can be categorized into three main groups, each responsible for the formation of a different group of fog patterns. Additionally, distinct regional differences could be identified in the diurnal and annual fog frequency cycles and the derived region‐specific frequency variations were used to draw conclusions about the fog types prevailing in these regions.
