Modeling Study on the Coupling Effect of the Horizontal Electric Field and Winds in the Ionosphere

  • 摘要: 设计了一个将电离层水平电场与风场耦合的模拟方案,研究了电流函数和风场在耦合前后的变化与差异. 研究发现,水平电场与风场相互反馈后,风场的变化比电流函数小. 经向风在白天有较明显的差异,夜晚的差异比白天小,主要出现在中高纬地区,并随高度的增加而增大,300km左右达到最大值,其后几乎保持不变. 纬向风有与经向风相似的变化,但纬向风耦合前后的差异比经向风小. 电流函数在耦合后有较大改变,两个涡旋强度都有较强增加,并且北半球的增强大于南半球,而夜晚差异较小. 结果表明,在研究的高度范围内,风场对电场的控制作用大于电场对风场的影响.
