将大气科学的数值诊断与生物地球化学方法相结合,在深入研究2005～2006年春夏季东海赤潮事件与气溶胶时空关系并对两个测点大气颗粒物(TSP)连续监测的基础上,建立了季风与东海赤潮的潜在关系模型.结果表明,在研究年内东海的每一次赤潮均与随气流下沉的、来自西北(冬季风的方向)的气溶胶密切相关,杭州和天台两地TSP中元素丰度与当地土壤背景有较大差异,表明大气颗粒主要由冬季风带入,大气颗粒物中铁和磷的含量呈显著相关性,它们主要存在于颗粒间的胶结物中,赤潮藻对铁和磷限制性吸收与光照强度有关.这些研究结果为揭示东海赤潮频发机理提供了新的信息,也为通过监测来自西北的气溶胶和垂直气流来预警预报东海赤潮提供了科学依据.
Combining the numerical diagnosis of atmospheric science and biogeochemical methods, the relationships between the red tide events in the East China Sea in spring and summer of 2005 ~ 2006 and the spatio-temporal relationships of aerosols were studied. Based on the continuous monitoring of the atmospheric particles (TSP) And the tidal flats in the East China Sea.The results show that each red tide in the East China Sea is closely related to the aerosol from the northwest (the direction of the winter monsoon) that sinks with the air flow in the study year, and the elemental abundances of TSP in Hangzhou and Tiantai Degree and local soil background are quite different, indicating that the atmospheric particles are mainly brought by the winter monsoon, the atmospheric particulate matter of iron and phosphorus content was significantly correlated, they are mainly present in the intergranular cement, red tide algae restrictions on iron and phosphorus Sexual absorption is related to light intensity.These results provide new information for revealing the mechanism of frequent occurrence of red tide in the East China Sea and provide a scientific basis for early warning and forecasting of red tide in the East China Sea by monitoring aerosol and vertical airflow from the northwest.
