| 摘 要： | 2008年3月和2009年2月，厦门海域发生了以血红哈卡藻为优势藻种的赤潮，两次赤潮具有发生时间早、持续时间长的特点。针对近两年厦门海域两次在冬季爆发血红哈卡藻赤潮的现象，本文分析了赤潮期间的环流形势和水文气象条件。结果表明，厦门海域血红哈卡藻赤潮发生前后，1000hPa环流形势表现为西南地区的倒槽或者气旋，并随着冷空气的北退而向内陆地区延伸，台湾海峡的气流多为东南到西南向，气温和水温持续回升、风速偏弱、相对湿度偏高，盐度长时间维持较低水平，此种环流形势和水文气象条件促使了厦门海域冬季赤潮的发生。

| Abstract: | A dominating species of Akashiwo sanguinea red tide occurred in Xiamen sea area on March 15th in 2008 and February 5th in 2009. They both have two characteristics of early occurred and lasted for a long time. In order to find a reasonable explanation of the red tide happened in winter, we analysed the circulation patterns and Hydrometeorology on red tides outbreak. The result showed that early appeared wanner circulation patterns, continuously increased air temperature and water temperature, and stable weather conditions lead to the outbreak of red tide in winter. |
