不同吸湿性的气溶胶对云和降水影响研究进展

Progress in Impacts of Different Hygroscopic Aerosols on Cloud and Precipitation

  • 摘要: 气溶胶、云、降水相互关系是现今大气科学的前沿领域。本文总体概括了气溶胶作为云凝结核和冰核,对云宏微观物理特性及降水的影响原理研究的主要成果。并根据气溶胶自身化学性质的吸湿性,从吸湿性气溶胶和非吸湿性气溶胶两方面,重点探讨了模拟研究中,硫酸盐、海盐、沙尘、黑碳气溶胶对于云和降水的影响,以及各类气溶胶与其它类型气溶胶相比,作用于云降水的不同方式。提出之前研究工作的不足,以期为今后该方向的研究提供一些思路。

     

    Abstract: The interaction of aerosol、cloud and precipitation is one of the most attractive fields in atmospheric research.As CCN,GCCN and IN of cloud,the comprehensive impacts of aerosols on cloud properties and precipitation are given firstly.And then,aerosols were classified as two kinds based on their hygroscopic:one is hygroscopic aerosol (including sulfate,sea-salt,nitrate,ammonium salt,some hygroscopic organic principles),and the other is non-hygroscopic aerosol (including dust and black carbon、some organic principles).As the key issue of this study,we paid close attention to the different influences of sulfate,sea-salt,dust and black carbon on cloud and precipitation,and detailed the special work ways of each one's compared with others.Finally,some deficiencies of previous studies are discussed for future researches.
