This paper provides a perspective based on the evaluation of scientific evidence of hail suppression activities in Mendoza, Argentina. The province of Mendoza was home to several cloud-seeding projects over the years intended to prevent hail damage to agriculture. Those projects were motivated by the paramount importance of wine production for the regional and national economy. We discuss the uncertainties and gaps in knowledge identified in the results from the hail suppression activities, framing the available research over the study area on a global context. The results of this study indicate that there is no unequivocal scientific evidence that proves a statistically significant reduction of hail frequency and size as a consequence of hail suppressing activities in Mendoza. Such lack of evidence questions the reliability of the projects after almost 60 years of cloud seeding. By analyzing the existing gaps in knowledge in terms of observations, modeling evaluations and understanding of severe convective systems, the study provides a description of future directions and alternatives for hail damage mitigation that need a better science-policy integration. This study can be replicated in other regions where hail suppressing activities are taking place.

阿根廷门多萨 60 年的冰雹抑制活动：不确定性、知识差距和未来展望

本文提供了一个基于评估阿根廷门多萨防雹活动的科学证据的视角。多年来，门多萨省开展了多个云播种项目，旨在防止冰雹对农业造成损害。这些项目的动机是葡萄酒生产对区域和国家经济的重要性。我们讨论了防雹活动结果中确定的不确定性和知识差距，在全球范围内构建了研究区域的可用研究。这项研究的结果表明，没有明确的科学证据证明门多萨的冰雹抑制活动在统计上显着减少了冰雹的频率和大小。经过近 60 年的云播种，这种缺乏证据的问题对项目的可靠性提出了质疑。通过分析在观测、建模评估和强对流系统理解方面的现有知识差距，该研究描述了需要更好的科学政策整合的减轻冰雹损害的未来方向和替代方案。这项研究可以在其他正在进行防雹活动的地区进行复制。
