2007年太湖蓝藻暴发的气象条件分析

目的]分析2007年太湖蓝藻大暴发的主要气象因素。方法]以邻近太湖的东山气象站观测资料为代表,分析了2007年太湖蓝藻暴发时气象条件与同期历史气象条件的关系。结果]气温持续偏高和光照充足,为蓝藻的正常生长发育提供了热量保障;少雨和平均风速偏小为蓝藻颗粒的上浮和聚集而形成水华提供了保障。结论]2007年太湖蓝藻大暴发主要是由气候条件异常所造成的。所以,应加强气象条件与蓝藻暴发的关系研究,提高太湖蓝藻的气象预警能力。

Meteorological Condition of Blue-green Algae Fast Growth of Lake Tai in 2007

Objective] The research aimed to study main meteorological factors of blue-green algae fast growth of Lake Tai in 2007.Method] The data of Dongshan weather station in 2007 was deputy to analyze the relationship between same history time meteorological conditions and the time of blue-green algae fast growth.Result] Continuance higher temperature and enough sunshine supplied safeguard on the quantity of heat for the growth of blue-green algae.Few rain and low mean wind supplied safeguard for the granule of blue-green algae on the surface and conglomeration.Conclusion] The climate anomaly aroused blue-green algae fast growth of Lake Tai in 2007.So,the study of the relationship between meteorological condition and blue-green algae fast growth of Lake Tai should be strengthened so as to improve the ability of weather forecast.
