摘　　要：沙尘气溶胶对气候变化、生态环境和人类生命健康均会产生严重影响,亟待对其进行系统性研究。数值模式是研究沙尘气溶胶的有效工具,能够模拟沙尘的起动、传输、扩散及清除等过程。然而,由于起沙参数化方案的不完整及模式输入场的不确定性,导致数值模式的模拟结果存在较大误差。以此为立足点,论述沙尘气溶胶观测方式、数值模式发展历程、起沙参数化方案进展以及资料同化研究进展。并基于目前的研究现状,分析现阶段利用数值模式进行沙尘气溶胶研究过程中存在的问题,进一步提出未来的发展方向。通过全面回顾沙尘气溶胶数值模拟的研究进程,以期为相关领域研究提供参考和启发。Dust aerosols have a profound impact on climate change,the ecological environment,and public health,highlighting the importance of systematic research.Numerical models serve as effective tools for the investigation of dust aerosols because they enable the simulation of processes,including dust emission,transport,dispersion,and deposition.However,substantial discrepancies remain in the simulation outputs of numerical models,which are largely attributed to incomplete dust emission parameterization schemes and uncertainties in the model input fields.We focus on methodologies for dust aerosol observation,advancements in numerical model development,progress in dust emission parameterization,and recent strides in data assimilation research.Based on the current research status,we analyzed issues in the research of dust aerosols using numerical models and outlined prospective avenues for future research.Through a comprehensive review of the advancements in numerical simulation studies of dust aerosols,we hope to offer valuable insights and serve as a reference for further research in related fields.
