强震前带电气溶胶逸出对电离层电场的影响
  • 摘要

    采用准静态模型近似描述地表异常电场传播到电离层的过程,建立了强震前带电气溶胶排放产生的附加电流,造成大气层-电离层传导电流扰动,最终造成电离层中电场扰动的计算方法;分析了电离层中电场发生明显扰动的区域大小与带电气溶胶排放参数的对应关系,并根据我国川滇地区和大华北地区强震等震线的特点,计算了不同等震线长短轴比值下,电离层中电场扰动面积随地震震级及带电气溶胶数密度的变化规律.结果表明:强震前气溶胶浓度远大于能引起电离层异常的最小气溶胶浓度值,会在地表处产生一个幅值小于100 V·m-1的异常电场,并在电离层内产生幅值大于10 mV·m-1的扰动电场;在相同气溶胶粒子数密度和相同震级条件下,等震线长短轴的比值k越小,电离层中电场异常区域越大.
