东亚旱区气溶胶、云及其相互作用研究进展

东亚干旱半干旱区(简称为“东亚旱区”)是全球干旱带的重要组成部分,该区域水资源短缺,沙尘暴频发,沙尘气溶胶对大气辐射收支和云微物理过程的影响不可忽视。本文回顾了近年来东亚旱区气溶胶及云相关科学问题的研究进展,重点讨论了气溶胶、云特性以及气溶胶-云相互作用问题。东亚旱区大气中的气溶胶以沙尘为主,且春季多于其他季节;同时,该区域云水资源丰富,且以高云为主,夏季云量显著偏多。沙尘气溶胶可直接影响辐射收支对大气产生加热作用,并通过间接和半直接效应对云微物理过程和降水产生影响。由于云微物理观测资料稀缺,加之模式参数化方案的不准确,导致东亚旱区沙尘气溶胶-云相互作用仍存在较大的不确定,减小气溶胶、云所带来的不确定性是未来气候变化研究中亟需解决的科学问题。     

适用于寒旱区十要素无人自动气象站的研制

采用DT500数据采集器作为中心控制系统，研制成具有风向、风速、空气温度、空气湿度、地温、气压、日照、蒸发、辐射和降雨量等10个参数全自动采集的气象站系统。该系统适用于高寒、高湿、强风沙无人区等恶劣环境下正常工作。     

Editors-in-Chief Guodong Cheng and Ximing Cai

Editor-in-Chief Guodong Cheng, Chinese Academy of Sciences （CAS） Academician and the fotmder of the Sciences in Cold and Arid Regions （SCAR）, is now a Professor of Geocryology and Water Resources Engineering at the Cold and Arid Regions Environmental and Engineering Research Institute （CAREER1）, CAS. He received his BS in Hydrogeolog3＇ and Engineering Geology from the Beijing College of Geology in 1965. He was one of a few scientists who visited the US and Canada and initiated international scientific exchange in the late 1970s. As a visiting scholar in 1984-1986, Professor Cheng conducted his research on water migration in freezing and thawing soils and repeated ice segregation mechanisms in the US Anny Corps of Engineers （USACE） Cold Regions Research and Engineering Laboratory （CRREL） at Hanover, NH, and received the honour of the CRREL Research Fellow due to his achievements. The international cooperation programs later expanded successthlly into many other cotmtfies, such Russia and the former Soviet Union, European countries, Japan, mid Mongolia, with great recognition in the pennaffost commtmities.
