从观测资料出发，讨论了ENSO对中国夏季气候变化的影响及其机制。结果表明，在ENSO发展阶段，热带西太平洋夏季海温偏冷，南海和菲律宾附近对流活动可能较弱。因此，副热带高压向南移动。因此，在中南半岛半岛和华南地区可能发生干旱。盛夏江淮地区副热带高压偏弱，长江流域至淮河流域易发生洪涝灾害。相反，在ENSO衰减阶段，菲律宾附近对流活动可能较强，副高北移，可能导致江淮流域出现干旱。
The influence of ENSO on the summer climate change in China and its mechanism from the observed data is discussed. It is discovered that in the developing stage of ENSO, the SST in the western tropical Pacific is colder in summer, the convective activities may be weak around the South China Sea and the Philippines. As a consequence, the subtropical high shifted southward. Therefore, a drought may be caused in the Indo-China peninsula and in the South China. Moreover, in midsummer the subtropical high is weak over the Yangtze River valley and Huaihe River valley, and the flood may be caused in the area from the Yangtze River valley to Huaihe River valley. On the contrary, in the decaying stage of ENSO, the convective activities may be strong around the Philippines, and the subtropical high shifted northward, a drought may be caused in the Yangtze River valley and Huaihe River valley.
