摘　　要：利用北半球５００ｈＰａ月平均位势高度场资料，揭示了夏季（６—８月）青藏高原位势高度场的长期振荡及其与两大洋副热带环流的相互联系。并分析了这种长期变化对全球和中国气候的影响。sing monthly 500hpa height data in the Northern Hemisphere, a notable stage pro perly of long-term change of the geopotential height over the Qinghai-Xizang plateau in summer has been found. This feature is consistent with long-term oscillation of the subtropical circulation over the eastern Pacific and Atlantic. Additionally, its relation to the climate changes of China and the other regions in the world is also discussed.
