As the third pole of the world， the Tibet Plateau （TP） is one of the natural landforms， which has the most significant impact on global weather and climate. The thermal effect of the huge land surface deep into the middle of the troposphere directly affects the atmosphere， which not only forms the climate pattern in Asia， but also leads to climate change in the northern hemisphere and even the world. In the northern part of the TP， there is the largest desert group in the mid-latitudes of the northern hemisphere. Compared with other underlying surfaces including the TP， the desert has the characteristics of large surface albedo， low soil heat capacity， and low water content， which is an important source of sensible heat in the earth system and even plays significant roles in global and regional energy balance and climate changes. TP and its northern vast desert area—The two important terrestrial systems constitute a unique symbiotic geographical unit in the world， where land-atmosphere coupling must be related to each other through a certain process. Drought is a common and extremely serious natural disaster in the world. China is one of the countries where droughts occur most frequently. Under the background of climate change， droughts also tend to occur more frequently and worsen， especially in the north China. The causes of drought are complex， and they have always been a difficult and hot spot for research in related fields both at home and abroad. Starting from the land-atmosphere coupling process of the plateau-desert symbiosis geographic unit， what mechanism is used for the formation and evolution of drought in northern China is a frontier topic worth exploring. This article summarizes the latest advances in atmospheric scientific research on TP and the research on arid and semi-arid land surface processes including desert areas in recent years，from which we condense the key scientific issues in the research on the impact of the land-atmosphere coupling process between TP and the northern desert on drought in China for the purpose of reference and helping scientific and technological workers to carry out related exploration.
