【摘要】：为揭示2015年黄海区域浒苔演变特征,利用MODIS(moderate-resolution imaging spectrometer)数据,通过计算漂浮藻类指数(floating algae index,FAI)建立了浒苔信息的数据集,进而获取了浒苔的时空变化规律特征。研究发现,5月13日浒苔条带最早出现在苏北近岸,之后浒苔条带向北和向东漂移,浒苔覆盖面积逐渐变大;向北漂移的浒苔逐渐发展成大规模聚集的形态,而向东的条带仍旧是分散的形态;向北漂移的浒苔条带6月12日到达半岛顶端后出现大规模登陆的情况,登陆的依次顺序为乳山—青岛—海阳;在苏北近岸的浒苔一直持续到8月5日。对2015年浒苔时空演变特征与往年情况进行初步对比分析,发现其与2013年浒苔漂移路径和登陆过程存在显著差异,具有很强的年际差异。
[Abstract]:In order to reveal the evolution characteristics of Enteromorpha enteromorpha in 2015, the data set of the information of Enteromorpha enteromorpha was established by calculating the floating algae index (Faii) of MODIS(moderate-resolution imaging spectrometer. The study found that in May 13th, the band of Enteromorpha enteromorpha first appeared near the coast of northern Jiangsu, and then the band drifted northward and eastward, and the coverage area of Enteromorpha margin gradually became larger. The northward drift of Enteromorpha enteromorpha gradually developed into the form of large-scale aggregation, while the eastward band was still a dispersed form, and the northward drifted band of Enteromorpha enteromorpha reached the top of the peninsula on June 12th. The order of landing is Rushan-Qingdao Haiyang, and the enteromorpha on the coast of northern Jiangsu lasted until August 5th. The spatiotemporal evolution characteristics of Enteromorpha enteromorpha on 2015 were compared with those of previous years. It is found that there are significant differences between the drift path and landing process of Enteromorpha enteromorpha in 2013, and there are strong interannual differences.
