摘　　要：利用卫星遥感、海岛站、海岸带日照和EC渤海格点等资料,采用同步资料叠加分析,对2004—2013年5—8月出现在河北海区26次赤潮个例进行综合分析.结果表明,气象环境条件是赤潮发生、发展及消亡的新因素,赤潮发生后1~2 d环渤海地区地面维持均压场状态;赤潮发生的主要时间段为6—8月,持续时间7~15 d,最高气温30~34℃,相对湿度78%~88%,平均风速1~2 m/s,日照时数6~8 h;单一的海洋生物、物理、化学因子集成预测赤潮发生的空报次数偏多,叠加气象环境预测因子空报次数明显下降.Using satellite remote sensing, island stations, coastline sunshine and EC Bohai Sea grid and other informationg comprehensive a-nalysis of 26 red tides occurred in Hebei sea area from May to August during 2004 - 2013 was carried out by using synchronous data overlay a-nalysis. The results showed that the meteorological environment conditions were the new factors for the occurrence, development and disappear-ance of red tide. The surface of the area around the Bohai Sea remained the state of pressure field 1-2 days after the occurrence of red tide. The main period of occurrence of red tide was from June to August, the duration was 7-15 days, the maximum temperature was 30-34 ℃ , the relative humidity was 78% - 88% , the average wind speed was 1-2 m/s and the sunshine duration was 6 - 8 h. The integration of single marine biology, physical and chemical factors had predicted that there were too many cases of frequent occurrence of red tides, and overlapped meteorological environment forecast factor significantly decreased the number of vacancies.
