摘要
有关文献指出:“赤潮发生起因因种而异……,但大体上气候气象条件诸如温度、风力、风向,季风转换、气-压等;海况、潮汐、流等以及海水的理化特征,如盐度、营养元素等,这些皆会成为某种赤潮爆发的因子或诱导因素”。根据赤潮监控区监测资料分析: 在南海赤潮多发区,海水富营养化条件已经具备,因此气象、水文要素条件就成为赤潮爆发的重要启动因子,而大气环流的维持与变化决定了气象、水文要素因子的稳定与变化,然而根据赤潮生物培养试验,从初期繁殖到后期的爆发性繁殖,直至达到赤潮生物密度,这一过程一般都需要4-5d的时间。针对这一现象,通过对近10a的赤潮发生个例进行统计分析,统计其生成前期的大气环流形势和水文气象要素,分析出赤潮生成前期的环流模式和筛选出诱发赤潮爆发的重要因子,并以此来作为预报赤潮生成的方法。依照此方法对2003年的赤潮进行预报,其效果是令人满意的。
Many literatures point out that there are diverse factors causing Red Tide eruption, but one of invariable factor is weather condition involve temperature, wind power, monsoon transform, air pressure, sea condition, tide, ocean current, salinity, eutrophic environment and so on. In the red tide high frequency area of the South China Sea, the eutrophic environment of sea water has already possess. So, meteorological phenomena, hydrology element terms become the importance factor to the red tide eruption. And atmospheric circulation maintenance of change decide meteorological phenomena, hydrology key element not to stabilize or change, moreover, living of red tide beings breed from initial stage to explosive reproduction stage, until reaching the biological density of the red tide, generally taking 4-5days. We analyze the red tide examples in past l0 years, count the weather circulation situation and hydro-meteorological element of it produce previous, find previous circulation mode and bring out important factors. The predicted result in 2003 according to this method was satisfied.
