Recently, “National Science Review” published the latest research “Attribution of Tibetan Plateau to the northern drought” done by Professor Liu Yuzhi (first author), Professor Huang Jianping (corresponding author) and three other authors from College of Atmospheric Sciences of Lanzhou University, and took it as a cover paper for key recommendations. Regarding the attribution of the Qinghai-Tibet Plateau to downstream precipitation, the previous studies have mainly focused on the Yangtze River Basin. The study of the relationship between the plateau and the drought in North China still needs to be deepened. This paper provides a new perspective for understanding the formation mechanism of drought in North China. It is of great significance for understanding the role of the Qinghai-Tibet Plateau in regional climate change and predicting drought in North China. It is another major research achievement made by Huang Jianping’s team in recent years.

The Qinghai-Tibet Plateau has an average elevation of 4500 meters and is known as the “Asian Water Tower”. In summer, the Qinghai-Tibet Plateau is an elevated heat source, which plays an important role in the weather and climate of the surrounding areas through thermal and topographic effects. The paper “Attribution of Tibetan Plateau to the northern drought” proposed a dynamic mechanism for the impact of Qinghai-Tibet Plateau on the drought in North China in summer from a new perspective. It is found that when the subtropical westerly jet is northward in summer, the westerly wind over the plateau weakens, and the water vapor, cloud water resources and dust particles that can be used as the atmospheric ice core decrease from upstream to north China, resulting in the decrease of summer precipitation and frequent drought in north China.

The research was co-funded by the Chinese Academy of Sciences Pilot (A) Project and the National Natural Science Foundation of China. The Lanzhou Institute of Arid Meteorology of China Meteorological Administration is the cooperative unit of this research.
