| 摘 要： | 利用二维低纬电离层－等离子体层时变理论模式,模拟太阳活动高年春分条件下垂直漂移和中性风强度改变对低纬F区电离层参量的影响.模式在所考察的磁子午面内求解等离子体输运方程,给出离子浓度和速度随纬度、高度、地方时的变化.模式计算结果显示,调整垂直漂移和中性风强度对低纬F区电离层电子浓度的影响与电离层所处磁纬、垂直漂移和中性风作用时段等有关,呈现出一些新特点.结果对分析不同条件下垂直漂移和中性风对低纬F区电离层影响具有一定的指导意义.

| Abstract: | Effects of variations of magnitude of E B vertical drifts and neutral winds on low-latitude ionosphere areinvestigated by using a two-dimensional low-latitude ionospherictime-dependent theoretical model. In the model ion transport equationsare solved by using splitting technique at fixed grid points alongmagnetic field lines, and densities and velocities of ions are outputtedon the given geomagnetic meridian. Modelling results show that theinfluences of adjusted magnitude of E B vertical driftsand neutral winds on low-latitude f0 F2 are dependent on magneticlatitude and local time. And some features not reported previously arealso mentioned in the paper. |
