摘要
应用2008年全年天津地区14个气象站的逐小时资料和6 h一次的地面常规资料,对渤海湾西岸(天津)海风时空演变特征进行了统计分析,结果表明:2008年全年渤海湾西岸的海风盛行于春夏季的14—17时,海风发生频率的最大值出现在夏季,近海站的海风风速主要集中在2—4 m/s,且春季的海风强度最大,秋季最弱,风向主要以东和南-东南方向为主;海岸带附近建立的海风一半以上都可向内陆传播至30 km远,最大可向内陆传播70 km以远,海风强度的空间分布则呈现出近海站高于远海站,近郊站大于城市站的特点。
Based on the hourly observational data from 14 automatic weather stations and the data from the 6-hourly general surface meteorological stations in Tianjin, the temporal and spatial characteristics of sea breeze over the Bohai west coast （Tianjin） in 2008 are analyzed. The result shows that sea breeze is prevalent from 14： 00 to 17：00 in spring and summer, and the highest frequency of sea breeze is in summer. In Dagang station, the annual frequency of sea breeze is about 31.0 %. The speed of sea breeze in standard stations is about 2 - 4 m/s, and the mainly wind direction is easterly and south-southeasterly. Over 50.0 percent of the sea breeze formed along the coast can spread into the inland about 30 km far away. The strength of sea breeze in coastal stations is greater than that in inland stations, and it＇ s stronger in suburban stations than that in urban ones.
