The SSTA of February and August in 1998 had two peaks, while the wind speed reached its maximum minus anomalies in January and August. In order to find the circulation anomaly in the South China Sea, the circulation of 19952000 had been calculated by the ECOM hydrodynamic numerical model. The elevation and circulation of January and August in 1998 indicated that there were great anomaly of elevation and circulation after this El Nio event.(1)In January, the whole South China Sea had positive sea level anomaly and anticyclonic velocity anomaly, so the cyclonic circulation was weaker than normal.(2) In August, the South China Sea had positive sea level anomaly, especially stronger in the east of Vietnam, and cyclonic velocity anomaly in south, anticyclonic velocity in north, especially strong in the east of Vietnam. So the cyclonic gyre in the north and the anticyclonic gyre in the south were both weaker than normal, and an anticyclonic gyre appeared in the east of Vietnam.

为研究南海环流在1997/1998年的异常变化，利用ECOM水动力模型计算了1995—2000年的南海环流场，分析了1998年1月和8月南海水位和环流的异常分布，二者均存在显著的异常：①1月，整个南海海盆为正的水位异常，流场为反气旋异常环流，冬季控制整个南海海盆的气旋式环流减弱；②8月，南海海盆水位为正异常，特别是越南东部海区出现较强的正水位异常，南海南部的高水位中心扩大北移；异常流场表现为南部为气旋式异常环流，北部为反气旋的异常环流，且在越南东部海区形成非常强的反气旋异常环流中心，使得控制南海南部的反气旋环流和北部的气旋环流均减弱。

Based on the former studies, this paper promotes an innovation about this topic using new satellite altimetry data and hydrographic data along with numerical experiments: Firstly, the temporal variation of the deformation of Kuroshio accompanied by the periodically shed anticyclonic eddies from the Kuroshio bend is discovered; Secondly, the major mechanism of the anticyclonic eddy separating from the Kuroshio bend, which is the frontal instability, is brought forward and then proved; Thirdly, the factors with important impact on the periodical variation of the Kuroshio bend and the eddy shedding, which are the strength of the Kuroshio transport and the circulation in the winter SCS, are determined.

本文在前人工作的基础上，利用了最新的卫星遥感资料和海洋调查资料，通过数值模式的数值实验，得到了以下前人没有得到的创新成果：发现在吕宋海峡处黑潮的形变随时间变化，并伴有反气旋涡周期性地从黑潮主体中脱落；提出并证明了吕宋海峡黑潮锋附近的锋面不稳定是反气旋涡从黑潮弯曲中脱落的主要机制；确定了对黑潮弯曲周期性变化以及反气旋涡脱落有重要影响的物理因素是黑潮流量的大小及冬季南海局地环流。

Before the occurrence of ENSO, due to the anticyclonic anomaly in midlatitude of the South Indian Ocean, the anticyclonic anomaly over Australia tends to be enhanced through the dispersion of Rossby wave; In the meantime, the equatorial convergence of the southerly anomaly off the east of Australia and the northerly anomaly in the Philippine excite the onsets of the westerly anomaly in the equatorial western Pacific and the occurrence of ENSO.

在ENSO发生前，南印度洋中纬度为反气旋异常，并通过Rossby波的频散作用加强了澳大利亚附近的反气旋异常；同时，澳大利亚东部沿海的南风异常与菲律宾附近的北风异常在赤道辐合，促进了赤道西太平洋西风异常的爆发和其后ENSO的发生。

When the spatial pattern is meridionally anti-symmetric, in the north-warm/south-cold years, an anticyclonic anomaly circulation exists over the warm pool at 850hPa, the easterly near 15°N and the westerly near the equator are greatly strengthened, while the center of the 200 hPa anticyclonic circulation moves to the East Asia, and the Hadley circulation is affected evidently, so the summer rainfall may be above normal in the middle and lower reaches of the Yangtze River, and vice versa.

当SSTA为南北反对称分布时，北暖南冷年850hPa暖池区上空为一反气旋偏差环流，15°N附近东风气流和赤道附近西风气流增强，200hPa反气旋偏差环流中心移到东亚大陆上空，长江中下游地区为上升气流，降水明显增多，华北地区为下沉气流，降水减少；冷异常年则相反。

It is shown that over the top layer of a heating region, although there is no diabatic heating, but still exist ascent, divergence, anticyclonic circulation, and cold center.

在加热区的上空尽管非绝热加热为零，仍然存在上升、辐散、反气旋环流及冷中心，证明这是由于"过流"引起的。

The process of the anticyclonic eddy breaking off from the Kuroshio bend is closely related with the increase of the cyclonic eddy at the southern part of the Kuroshio bend.

Among them, thestrongest and largest is the MCS on 26 July, which developed under the conditions of the great upper-levelnearly-circular Qinghai-Xizang anticyclonic high and driven by the strong low-level thermal forcing andconditional instability.
