“…For regression analysis, a dummy variable which takes only the value of 0 or 1 is extensively employed to distinguish the categorical effect (Chelani & Gautam, 2022;He et al, 2014). In the study, the interference of acoustic field for each rainfall event was regarded as a dummy variable, the widely used ordinary least square method (OLS) (Kim et al, 2018;Li et al, 2021;Zhang et al, 2021) was applied to analyze the dependence relationship of average rainfall intensity with acoustic interference and meteorological variables.…”

For securing sustainable water resources, traditional solutions including seawater desalination are limited due to high cost and restricted operating conditions.Plateau. Statistical analysis was applied to evaluate the effect of acoustic wave on rainfall stimulation. The results of average rainfall intensity distribution using ordinary least square analysis disclose that acoustic interference has a considerable effect on rainfall enhancement. Such a rainfall enhancement effect increases significantly along with the increase of rainfall duration which is the index of cloud precipitation potential.For rainfall events with the duration more than two hours, the average rainfall intensity was improved by 72% with the acoustic wave effect over the experiment site. The phenomena are consistent with the fact that clouds with larger precipitation potential contain more cloud droplets which are beneficial to the acoustic coagulation process.

“…With many people and industries gathering in cities and many production and domestic sewage discharges, China's water resources face a dire situation. Problems, such as water shortage, severe water pollution, and deterioration of the ecological environment, are becoming increasingly prominent [3]. Water shortage has become a bottleneck restricting China's urbanization and economic development [4].…”

“…On the one hand, the overall water situation in the western region is very complex. In 2018, the water resources of the 12 provinces and municipalities in the western region were 1615.28 billion m 3 , accounting for 58.8% of China's total water resources [5]. However, the water resource endowment of each province and urban area in the region is quite different.…”

Urbanization and climate change have combined to exacerbate water shortages in cities worldwide. While rapid urbanization is faced with the risk of water resource shortage, there are few studies on the impact of water resource shortage and the ecological environment in mega-regions. Taking the three major urban agglomerations in Western China as an example, the spatial–temporal agglomeration pattern and driving force for the risk of water shortage are analyzed. First, a new comprehensive index system for environmental risks of water resources has been established, which can be used to assess spatial changes in water resource shortage risks. Secondly, the relationship between water resource shortage and the urban agglomeration effect is discussed in regards to water resource vulnerability, exposure, and recoverability. The results showed: (1) From 2000 to 2018, the risk of total water shortage in 12 provinces (cities) in Western China decreased from 3.42 to 2.59; the risk of total water shortage in the Guanzhong Plain urban agglomeration dropped the fastest, with an average annual decline rate of 10.57%. (2) Water resource shortage in different cities of the three major urban agglomerations is out of sync in time and space; the risk level of water shortage is high in the north and low in the south. (3) Geological environmental change is an important influencing factor of water resource shortage; the negative impact of industrial water use on the risk of water shortage is the largest, with a contribution of 24.9%. In addition, this paper also puts forward policy suggestions to alleviate the risks of water shortage in the urbanization process in the western region. This research can provide a scientific basis for the sustainable development of urban water resources.
