【摘要】：本文主要对大连近海海雾气候特征及形成机理进行了研究。通过统计分析大连、长海地区历史监测实况资料，从大雾年际变化、年变化、持续时间、风和能见度几个方面进行数据分析统计，得出了大连近海春夏季和秋冬季大雾气候特征；通过对大连近海各个季节大雾的影响因子的分析，，得出了形成大雾的条件和主要影响因子；通过分析大雾过程的天气概况、环流特征、动力和热力特征等，得出了影响大雾生成、发展、保持和消散因素；分析了影响大雾产生的主要天气系统及个例；得出了海温分布、风速、逆温层等条件对大连近海产生海雾的结论。
[Abstract]:In this paper, the climatic characteristics and formation mechanism of offshore sea fog in Dalian are studied. Through statistical analysis of the historical monitoring data in Dalian and the Changhai area, the data are analyzed from the following aspects: interannual variation of fog, annual variation, duration, wind and visibility. The climatic characteristics of heavy fog in the coastal waters of Dalian in spring, summer and autumn and winter are obtained. Through the analysis of the influence factors of fog in each season of Dalian offshore, the conditions for forming the fog and the main influencing factors are obtained, and the synoptic situation of the fog process is analyzed. The factors influencing the formation, development, maintenance and dissipation of fog are obtained. The main weather systems and examples affecting fog generation are analyzed, and the distribution of sea surface temperature and wind speed are obtained. Conclusion that sea fog is produced in Dalian offshore under the condition of inversion layer.
