青藏高原夏季降水研究进展

Research Progress on Summer Precipitation over the Tibetan Plateau

  • 摘要: 青藏高原夏季降水是高原气象研究关注的重要领域。受高原夏季各个层次的天气系统的影响,在高原多尺度地形的强迫作用下,高原夏季降水表现出复杂多样的时空分布和演变特征。回顾了国内外学者在高原夏季降水特征和影响机理方面取得的主要研究成果,分为以下三个方面:高原夏季降水的时空分布和演变特征;影响高原夏季降水的高原天气系统,包括南亚高压、500 hPa高原高压、高原切变线、高原低涡和高原中尺度对流系统等;高原地形对高原的强迫机制,包括大尺度的动力和热力强迫,以及高原上中小尺度地形的强迫作用。最后对三方面的研究进行了总结,并对未来的研究进行了展望。

     

    Abstract: The summer precipitation over the Tibetan Plateau (SPTP) is a key topic in Tibetan Plateau meteorology research. Under the influence of the synoptic systems on different levels and multi-scale topographic effect of the plateau in summer, SPTP features complicated and varying spatio-temporal distribution characteristics. This paper reviews the research progress on SPTP characteristics and the mechanisms causing SPTP. The review is organized into 3 aspects: 1) the spatio-temporal distribution and variation characteristics of SPTP. 2) the synoptic systems that affect SPTP, including the South Asia high, the 500 hPa high over the plateau, the plateau shearline, the plateau vortex and the mesoscale convective systems over the plateau. 3) the topographic forcing of the plateau, including the large-scale dynamic forcing and thermal forcing, as well as the mesoscale topographic forcing. Lastly, a summary of the past research progress and an outlook of future research are given.
