Fig. 2From: Full-particle simulations of instabilities in a thin current sheet of the magnetospheric system prior to substorm onsetInitial conditions of the B z component in the equatorial plane (z/d=0). a–d show the B z component in Run(0)–(3), respectively. Purple lines indicate the magnetic field of the DL region B z0, green lines indicate the small northward magnetic field in the CS B z1, red lines express the enhancement of B z2, and black lines show the total of B z Back to article page
