| 摘 要： | 电离层环境变化对电子信息系统具有重要影响，其可能引起短波通信质量下降甚至中断，导致导航信号闪烁和误差增加等. 研究电离层环境特性对于评估空间环境对通信、雷达及导航装备的影响具有重要意义. 本文根据乌鲁木齐电波环境观测站50余年数据，研究了乌鲁木齐地区电离层F层临界频率、F层底高、Es层临界频率的日变化、季节变化和长期变化情况，同时根据HWM07高空风场模型研究了乌鲁木齐地区高空风场的昼夜和季节变化特性.

| Abstract: | There are important effects on the electron equipments for the variations of ionosphere, such as it can induce shortwave communications quality decline indeed interrupted, navigation signal scintilla and error increase, space craft orbit change, surface charging up and proton event etc. In a word, it is important to study ionospheric characteristic and its impaction on electronic equipments. Based on Urumchi ionospheric vertical sounders and its more than fifty years data, the daily variations, seasonal changes and long-term trends of the ionosphere over Urumchi were studied. Some meaningful conclusions are given at the end of the paper. |
