By making use of the hail observation data from 9 fundamental meteorological observation stations and 87 hail suppression operation points in Bayannur City, Inner Mongolia throughout the period spanning from 1970 to 2019, and by means of the application of statistical methods, a meticulous and extensive analysis is carried out on the diverse characteristics of interannual variations, monthly variations, diurnal variations, durations, and spatial distribution of hail in Bayannur City. The resultant findings disclose that: (1) Over the course of the past 50 years, the average annual number of hail days in Bayannur City amounts to 16.4 days. The peak value is an impressive 22.8 days in the 1980s. However, a strikingly pronounced and significant downward trend is readily observable since the dawn of the 21st century, approximately reaching around 10 days. Hail manifests distinct and obvious seasonality. The probability of its occurrence in summer is a considerable 76.44%. Specifically, July witnesses the highest incidence of hailfall. Hail predominantly emerges within the timeframe of 12:00 to 20:00, accounting for a substantial 83.38%. Among these intervals, the highest probability of hailfall occurs precisely from 15:00 to 16:00, attaining an elevated 17.01%. (2) The proportion of hail durations within 5 minutes is the most prominent, constituting a significant 50.20%. The average annual duration of hail demonstrates a discernible upward trend. The duration of hail in July is the longest, with an average of 7.09 minutes. (3) The spatial distribution of hail is characterised by a higher frequency in the south and a relatively lower occurrence in the north. The maximum is 282 days in Urad Front Banner, while the minimum is 80 days in Urad Rear Banner. At the township level, there are 4 hailfall centres with more than 100 days from west to east on the south side of the Yinshan Mountains. In combination with the moving paths of hail clouds, it is of utmost importance to establish additional hail suppression operation points in areas such as Hailiutu and Wujiahe Town in the northern part of Bayannur City. This not only enhances the intensity of artificial hail suppression operations but also effectively minimises the losses caused by hail disasters. Such measures aim to provide more robust protection for agricultural production as well as people’s lives and property, thereby contributing to the stable and sustainable development of the region. It is expected that these efforts will lead to improved meteorological disaster prevention and mitigation capabilities, and ultimately promote the harmonious coexistence between human beings and nature in this area.
