磁赤道（magnetic equator）是一个地球物理学名词，是指地球表面磁倾角为零的各点的连线。
由于地磁位型的不同，发生率的分布并不具有经度对称性，即使在磁赤道附近也如此。
Due to the magnetic effects, the occurrence rate of the instability is not symmetric in longitudes even at the magnetic equator.
以上特性显示这些波动可能产生于磁赤道平面附近，在向中高纬传播时被TC - 2观测到。
The above observation reveals that these waves may originate near the equatorial plane and propagated to high latitudes then be observed by TC-2.
将笔者以前关于近磁尾赤道面附近的漂移气球模不稳定性工作推广到非赤道区和存在非定常地向流的情形。
Previous work on drift ballooning instability in the equatorial region has been extended to include a decelerated non stationary flow and to consider the off equator regions.
