作为灾害性空间天气的一种重要志源——日冕物质抛射(CME),一直是空间物理学家关注和研究的热点;另一方面,做为空间天气的最直接表现的层次——近地空间环境,随着地基探测手段的不断建立和完善也成为日-地关系链研究中的一个重要方面.主要从空间天气这因果两端出发,对CME的对地有效性问题,以及近地空间环境的探测和动力学过程进行了初步研究.在CME的对地有效性方面,主要工作包括:(1)CME冰淇淋锥模型的建立;(2)分析了CME对地有效性的主要影响因素;(3)分析了CME对地有效性的特大地磁暴起因.在近地空间环境研究方面,主要工作包括:(1)参与建立了中国科学技术大学米-瑞利-钠荧光激光雷达,并给出其对80~110km高度钠层的初步观测结果;(2)利用流星雷达研究了中高层大气周日、半日潮汐的典型相关模式.

This work focused on the two aspects of the space weather.One is the sources of the disaster space weather-coronal mass ejections(CME). We set up a new ice-cream cone model to describle the CMEs and discussed the geoeffectiveness of CMEs.The other is the end of the space weather-near-Earth environment. We introduced a newly installed Mie-Rayleigh-Sodium fluorescent lidar and its initial observations for the sodium layer between 80~110km,and also employed a meteor radar to study the mesospheric and low-thermospheric tides by canonical correlation alaysis.
