磁暴也会干扰远程雷达通讯，对远洋航行船只和跨洲飞行构成威胁。 |
| 5. | Solar flares are caused by magnetic storms on the surface of the sun and consist of eruptions of highly charged particles that travel at high speed through space
太阳的闪焰爆发因太阳表面的磁暴所引发，喷出大量高度带电的粒子以高速在太空中运行。 |
| 6. | A new computer model suggests the next solar cycle will be more active than the previous one , potentially spawning magnetic storms that will be more disruptive to communication systems on earth
显示，下一个太阳活动周期将比先前一个太阳活动周期更加活跃，它所引发的磁暴对地球上系统的破坏也将更大。 |
| 7. | A new computer model suggests the next solar cycle will be more active than the previous one , potentially spawning magnetic storms that will be more disruptive to communication systems on earth
美国科学家日前表示，新的计算机模型显示，下一个太阳活动周期将比先前一个太阳活动周期更加活跃，它所引发的磁暴对地球上通讯系统的破坏也将更大。 |
| 8. | Solar wind flows out from the corona the sun s outer atmosphere into interplanetary space at speed of between 300 and 900 km per second . it causes fluctuation to the earth s magnetic field , which we call magnetic storm . such event will cause deflection of compass needles
而太阳风则以每秒300至900千米的速度由日冕太阳外大气层向外抛射，进入行星际空间，对地球磁场造成扰动而产生磁暴，导致指南针指针偏移，严重的话更会导致电力受阻和电话线路中断。 |
| 9. | Several influence factors to result plasma drift in hainan were analyzed . in this paper the characteristics of ionospheric parameters variation were analyzed systematically and some new results in storm - time such as seasonal behaviors were obtained ; it is the first time to investigate the ionospheric drift behavior in hainan and some new results was obtained , the relationships between each two plasma drift velocity components in storm time in hainan were found and the electric filed variation in hainan ionosphere also was obtained ; the results also show that there are big differences of the ionosphere parameters bo and bl obtained from the data with that obtained from the iri - 2001 applied for hainan ; a new phenomena was found during a strong magnetic storm , that a layer with very strong electron density and density grad was found during the recovery phase of the storm , its horizontal scale is beyond 100km and temporal scale is about 2 hours , this phenomena repeated 3 times continuously . a type of negative disturbance in high and low latitude but positive disturbance in east - asia also has been found
本文较为系统地给出了海南地区电离层的参数变化特征，特别是得到了一些暴时与以往不同的季节特性；第一次给出了海南地区的电离层等离子体漂移特征，发现等离子体漂移暴时扰动在三个方向上有内在的联系，得到了电场变化曲线；研究结果还表明海南电离层的半厚指数和形状参数等与国际参考电离层iri - 2001存在很大差别；通过对强磁扰动事件期间的参数变化特性分析发现，在磁暴恢复相期间海南地区电离层底部存在一个电子密度非常大的高密度区，高密度区底部电子密度梯度随高度急剧增加，该区域的水平尺度可达100公里以上时间尺度约为2小时，连续出现过三次，这是一个在海南从来未发现的新现象；研究还发现了暴时东亚地区电离层扰动会出现高低纬负相而中纬正相的现象。 |
| 10. | Characteristics of variation and disturbances in low - latitude ionosphere were investigated based on the data observed in hainan under different magnetic activities and solar activities including variations and disturbances of parameters in different ionospheric layers , behaviors of plasma drift and a comparison with other low - latitude ionospheric station . the disturbance propagations from high to low latitude region during magnetic storm time are also investigated with analyzing the data obtained from the east - asian high - middle latitude stations
本文在观测数据分析的基础上研究了不同地磁活动和太阳活动条件下低纬电离层的变化和扰动特性，包括海南电离层各分层的参数变化和扰动特性，电离层漂移的变化特性，并与低纬度地区其他台站进行了对比分析，还对暴时东亚地区高中纬度地区台站的观测资料进行了分析，研究了电离层扰动从高纬到低纬的响应过程。 |
