| 摘 要： | 青藏高原作为耸入对流层中层的“巨大热岛”，其产生的热力强迫对东亚以及全球的天气气候起着举足轻重的作用。因此，关于夏季高原热源对下游降水影响及其机理的研究有助于加深对青藏高原影响下游天气气候的认识，提高青藏高原及下游降水的预报水平。本文针对青藏高原夏季热源的时空分布及演变特征、青藏高原热源在不同时空尺度上对下游降水的影响规律及物理机制，总结了已有的相关研究进展，指出了存在的主要问题，并展望了未来不同时空尺度上青藏高原热源对下游降水影响的研究方向，提出了值得进一步加强研究的重点与难点问题。

| Abstract: | As a “giant heat island” towering into the middle troposphere, the Tibetan Plateau produces thermal forcing that plays a pivotal role in the weather and climate of East Asia and the world. Therefore, the research on the influence of summer plateau heat sources on the downstream precipitation and its mechanism will help to deepen the understanding of the influence of the Tibetan Plateau on the downstream weather and climate, and improve the forecast level of the Tibetan Plateau and downstream precipitation. In view of the temporal and spatial distribution and evolution characteristics of heat sources on the Tibetan Plateau in summer, the influence of the plateau heat sources on downstream precipitation at different temporal and spatial scales, and the physical mechanism, the existing research progress is summarized, the main problems are pointed out, the future research directions of heat sources over the Tibetan Plateau on the downstream precipitation at the different spatial and temporal scales are indicated, and emphases as well as difficulties of further research are proposed. |
