人为源气溶胶的间接气候效应研究综述

A Review of Indirect Anthropogenic Aerosol Effect

气溶胶可以多种途径改变云特征来影响气候。作为凝结核,气溶胶可以增加暖云的云滴数和寿命,间接影响辐射和降水,即为气溶胶的第一间接效应和第二间接效应。观测(包括地面和卫星)和数值模拟是研究间接效应最主要的两种手段,目前这两种方法大多同时采用。本文介绍了气溶胶间接效应的原理及研究方法,并回顾国内一些研究和成果。

Aerosol can affect climate by changing cloud characteristics in many ways. As cloud condensation nuclei, aero- sol can vary indirectly radiation and precipitation because they change the warm cloud number and cloud lifetime. Those are so - called albedo effect and cloud lifetime effect received most attention recently. Observations, including ground - base and sat- ellite, and numerical simulation are the main research methods, they so for are often applied by coupled together. To understand the research of indirect aerosol effects, this paper introduces the concepts and research methods of indirect effect. Some work done by Chinese will also be mentioned.
