根据预报经验和统计结果,海雾的发生、持续、消散与某些天气形势下的空气物理属性及风场变化等有关。为探索海雾中期活动规律,本文利用1962年到1973年4、5月份历史天气图(中央气象局出版)及有关海雾资料,分析了黄海中北部春季海雾过程的发生和持续期间,地面天气形势、海上高压后部空气属性变性的规律[海雾过程定义:在大型环流背景稳定期间,大鹿岛、海洋岛、大连、砣矶岛、成山头、小长山、长岛、北隍城、石岛、青岛、千里岩、朝连岛、日照等12个测站中,8站以上有雾,称为海区有雾。本海区连续有雾的时段(间断时间不超过1天,视为连续)称为1次海雾过程]。认为与西藏高原东南部对流
According to the prediction experience and statistical results, the occurrence, persistence and dissipation of sea fog have something to do with the air physical properties and wind field changes in some weather situations. In order to explore the law of mid-term sea-fog activity, this paper analyzes the occurrence and duration of the spring sea fog in the north-central Yellow Sea from the historical weather charts of April and May 1962-1973 (published by the Central Weather Bureau) and the sea fog data. The definition of the sea fog process: during the stable background of the large circulation, the islands of Dalu Island, Ocean Island, Dalian, 砣 岛 Island, Chengshan Head, Xiaoshan, Long Island, Beibei City, Among the 12 stations in Shidao, Qingdao, Qianriyan, Chao Lian Island and Rizhao, more than 8 fog stations are called foggy in the sea area. Continuous foggy sea area (intermittent time does not exceed 1 day, regarded as continuous) called a sea fog process]. It is believed that the convection with the southeastern Tibet Plateau
