Abstract:
Tibetan Plateau Vortex (TPV) is a unique weather system over the Qinghai-Tibet Plateau. As the main precipitation system over the Qinghai-Tibet Plateau in summer, there is an important impact on the precipitation and other weather and climate in the surrounding and downstream areas of the plateau with the occurrence, development and movement of TPV. The Central Asian Vortex (CAV) is one of the important systems which cause severe weather such as rainstorm, short-time heavy precipitation, hail and continuous low temperature in Xinjiang, where the northwest of Qinghai-Tibet Plateau. The CAV significantly affects the weather and climate in its surrounding areas and the eastern and southern parts of China. TPV and CAV are low vortex systems located in different latitudes and ranges. Both of them are mainly active on the isobaric surface of 500 hPa, closely related to the Qinghai-Tibet Plateau and its surrounding areas. They are all located in the upper reaches of western China, which have far-reaching influence on the weather and climate of the downstream areas. A lot of achievements in the basic definition, activity characteristics and weather influence of the TPV and the CAV have been made respectively in earlier stage, but the possible relationship and influence between the two vortex are rarely discussed. On the basis of review, this paper mainly summarizes the research progress of the TPV and the CAV in the past 10 years, points out the existing problems, and emphasizes that the analysis of the relationship between the TPV and the CAV is an important direction in the future.
