摘　　要：陆-气相互作用会影响对流系统的初生和发展,进而影响降水的产生和分布,理解和明晰该影响机制和规律,对改进对流活动预报技术至关重要。系统总结了陆-气相互作用对对流系统形成、发展及其降水的影响机制,归纳了陆-气相互作用影响符号和强度的发生规律,进而剖析了陆-气相互作用对大气对流活动影响的复杂性和不确定性,最后提出了亟待解决的关键科学问题。未来需要针对陆-气相互作用的全部组成过程对大气对流活动的影响机制、响应敏感区和不同天气系统强迫下陆-气相互作用影响机制、影响机制的科学评估及验证、陆面过程和边界层过程在地球模拟系统的准确表达、陆-气相互作用与对流活动的互馈机制等开展深入研究,深刻揭示陆-气相互作用对大气对流活动的影响规律和机理机制,以期为改进和提高对流活动的预报能力提供理论支撑。The land-atmosphere interaction will affect the initiation and development of the convective system,which in turn affects the generation and distribution of precipitation. Understanding and clarifying the impact mechanism is crucial to improving the forecasting technology of convective activities. This paper systematically summarizes the influence mechanism of land-atmosphere interaction on the formation,development of convective systems,generalizes the influence sign and intensity of land-atmosphere interaction,and analyzes the complexity of land-atmosphere interaction on convective activities. Finally,key scientific issues that need to be resolved are put forward. In-depth research is needed in the future,including the influence mechanism of the entire composition process of land-atmosphere interaction on convective activities,the influence mechanism of land-atmosphere interaction forced by different weather systems,scientific evaluation and verification of the influence mechanism,parameterization and coupling of land surface processes and boundary layers process,and the mutual feed mechanism of land-atmosphere interaction and convective activities. The study of these issues can profoundly reveal the mechanism of the influence of land-atmosphere interaction on convective activities,with a view to providing theoretical support for improving and enhancing the forecasting capabilities of convective activities.
