摘　　要：大气冰核在冷云降水物理过程、人工影响天气、云和气溶胶的气候效应乃至全球变化等对大气和气候方面的研究中具有重要的意义。本文主要从大气冰核的观测方法、来源、化学组成、成冰活性、浓度时空分布及其与气象条件如天气系统、天气现象、气象因子等各方面综述了国内外近几十年大气冰核的研究进展,并在探讨国内外大气冰核研究现状的基础上,提出了未来大气冰核研究的重点和方向。It is significant to study ice nuclei（IN） concentration distributions in air for atmosphere and climate,such as physical processes of ice cloud precipitation,weather modification,climatic effects of cloud and aerosol.According to the materials at home and abroad,the observation methods and the sources of atmospheric IN,forming ice activity,the temporal and spatial distributions of IN concentration,and the chemical composition of IN were reviewed.The relationships between IN concentration and meteorological conditions,such as weather system,weather phenomenon,meteorological factors and so on were also summarized.At last,the further work task and study direction were put up.
