Along the road opened up by Ye Duzheng ancestors - from the Tibetan Plateau meteorology to the Tibetan Plateau dynamic meteorology

“The wind structure and heat balance in the lower troposphere over Qinghai-Xizang Plateau" published by Ye Duzheng, Luo Siwei and Zhu Baozhen in 1957 was a foundational article that opened up the development direction of the Tibetan Plateau meteorology. In the past 70 years, the study of the Tibetan Plateau has flourished. Based on the important conclusions of this epoch-making article, this paper briefly introduces some achievements of the Tibetan Plateau dynamic meteorology developed from the Tibetan Plateau meteorology: Based on the finding that the Tibetan Plateau "in summer is a heat source; in winter... may be a cold source", the theory of "TP-SHAP" was established, and the Tibetan Plateau is an important potential vorticity source in the atmosphere was proved; On the basis of revealing that "the lower layer has cyclonic rotation and turns upward to anticyclonic flow pattern" around the Plateau, the boundary potential vorticity circulation theory was developed, which proves that the climate change of a region is controlled by its boundary potential vorticity circulation, and the climate change in the northern hemisphere is affected by the potential vorticity circulations through the surface, tropopause and equatorial cross-section；On the basis of the discovery that "there are obvious double westerly branches and their confluence in winter" in the mean flow field over the Qinghai-Xizang Plateau, it is further pointed out that there is often an upper tropospheric front with large longitudinal and latitudinal potential vorticity gradients accompanying the double jet stream in the upper troposphere. These progresses prove that the developing theory of boundary potential vorticity circulation is an effective tool for studying regional weather development and climate change.
