| 摘 要： | 选用1987-2006年NECP 500hPa高度场及海平面气压场日平均再分析资料及沿海岸基、石油平台、海岛及船舶实时观测资料,统计分析了冬季造成黄渤海海域8级和10级以上大风天气过程;选用中国渔船安全分析报告1999-2005年风灾船损事故资料,分析了大风和船损灾害的关系.结果显示:(1)冬季影响黄渤海的冷空气过程主要是来自西北路径,占全部冷空气过程的50.4%.(2)造成海上8级以上大风的冷空气过程的天气类型主要是小槽发展型112次,占全部冷空气过程的50.0%;其次是横槽转竖型61次,占全部冷空气过程的27.2%.(3)近20年冬季冷空气大风过程次数呈下降趋势;(4)风灾事故占渔船全损事故的51.85%,冬半年突发性的冷空气大风是导致木质渔船出现风灾事故的主要原因.

| Abstract: | The weather system which caused strong winds in Bohai Sea and Yellow Sea from 1987 to 2006 was analyzed by using the NCEP reanalysis data of 500hPa height and sea surface pressure distribution,the in situ ground observations in the costal areas,oil platforms in the sea,islands and ship reports.Also the statistical data of fishery boat windage loss accidents from Analysis Report of China Fishery Vessel Safety(1999-2005) were used.The conclusions are in the following.(1) In winter the number of cold air from ... |
