| 摘 要： | 利用TOPEX／POsEIDON和Jason—1卫星高度计，SeaWiFS水色传感器和TMI微波成像仪等卫星遥感资料研究了南海中尺度涡旋对热带气旋“玲玲”（Lingling，0123）、“灿都”（Chanthu，0405）和“榴莲”（Durian，0621）的响应，得到以下研究结果：（1）位于热带气旋“玲玲”和“榴莲”移动路径右侧的冷涡在热带气旋经过后增强，表现在海面高度距平和海表温度的较大幅度下降，以及叶绿素a的爆发性升高；（2）位于“玲玲”移动路径左侧以及“灿都”路径上的暖涡在热带气旋经过后减弱，表现在海面高度距平和海表温度的下降，而叶绿素a变化不太明显；（3）当热带气旋“玲玲”和“灿都”经过暖涡时，热带气旋的强度迅速增大，这表明暖涡可能有助于热带气旋的加强．

| Abstract: | Response of the mesoscale eddies to tropical cyclone ＂ Lingling＂ （ 0123 ）, ＂ Chanthu＂ （ 0123 ） and ＂Durian＂ （0123） in the South China Sea are studied using satellite data from TOPEX/POSEIDON and Jason-1 satellite altimeter, SeaWiFS ocean color sensor and TMI microwave imager. We obtain the following results. （ 1 ） The cold eddy in the fight of tropical cyclone ＂Lingling＂ or ＂Durian＂ track was intensified after the tropical cyclone passing, evidenced by a relatively large decrease in sea surface height anomaly and sea surface temperature, and an explosive increase in chlorophyll a concentration. （2） The warm eddy in the left of tropical cyclone ＂Lingling＂ track or along the ＂Chanthu＂ track was weakened after the tropical cyclone passing, as shown in a decrease in sea surface height anomaly and sea surface temperature with no obvious change in chlorophyll a concentration. （3） As the tropical cyclone ＂ Lingling＂ or ＂ Chanthu＂ encountered with a warm eddy, their intensities were rapidly increased, indicating that the tropical cyclone tends to be enhanced by the warm eddy. |
