The region of solar - wind plasma between the bow shock and the magnetopause is known as the magnetosheath 在弓形震波和磁层顶之间充满太阳风电浆的区域，称为磁鞘。

When reconnection is initiated on the dayside magnetopause , the interconnected imf and geomagnetic field lines are swept back by the solar wind over the earth ' s poles , pouring energy into the northern and southern lobes of the long magnetotail on the nightside 当磁力线重连在昼侧的磁层顶上开始发生，连在一起的imf和地球磁场磁力线便被太阳风往后吹，扫过地球南北极，把能量灌入长磁尾的南北两叶。

Just as the passage of a supersonic jet through the atmosphere produces a shock wave , the encounter of the solar wind with the magnetosphere forms a shock wave ? known as the bow shock ? some 13 , 000 kilometers upstream ( that is , closer to the sun ) from the dayside magnetopause 就像超音速喷射机在大气层飞行时会产生震波，当太阳风碰上地球磁层，也一样会产生震波，我们称之为弓形震波，产生位置约在昼侧的磁层顶外13000公里处。
