摘要
大气冰核参与初始冰晶的异质形成,影响冰云的微物理过程和辐射性质。阐明大气冰核浓度、来源、性质及活化成冰的微观机制,是深入认识气溶胶与云相互作用的关键。本文梳理了近年来国内外在冰核测量技术、冰核活化机制、外场观测及其参数化方案等几个方面取得的进展,明晰了冰核研究存在的挑战。此外,本文也指出了我国加强大气冰核研究的必要性和迫切性。
Atmospheric ice nucleating particles(INPs)trigger the heterogeneous ice nucleation,which significantly affects the microphysics and radiative properties of ice clouds.For better understanding of the aerosol-cloud interactions and their associated climatic effects,it is crucial to elucidate the abundance,sources,and ice nucleation mechanisms of INPs in the atmosphere.This review compiles the recent progress made in the INP detection techniques,ice nucleation activities and mechanisms of representative aerosol particles,and the developed ice nucleation parameterizations based on the field and lab investigations.The critical challenges and open questions in the atmospheric INP research field are pointed out.Finally,we highlight the urgent needs to promote the ice nucleation studies in China.
