青藏高原大气低频振荡研究进展

摘要

青藏高原是大气低领振荡的活跃区和重要源地之一,近30 a来有关青藏高原大气低频振荡的研究已取得了很多成果。本文从青藏高原大气低频振荡的波谱特征、结构特征、传播特征、起源和维持机制以及其对下游地区天气及气候的影响等几个方面进行概述。并就该研究领域中未来的一些研究重点和关键点进行了展望。%Over the past 30 years,significant progress has been achieved on the low frequency oscillation（LFO） over the Tibetan Plateau which is one of the extratropical action centres and source regions of LFO.In this article,a review is summarized about the period,structure and propagate characteristics,origin and maintaining mechanism of the LFO over the Tibetan Plateau and the impacts of the LFO on weather and climate system.The further prospects of some key points in this area are proposed.
