Fig. 8

For the chorus element shown in Fig. 2a, a presents the right-hand mode wave magnetic field amplitude (Br), b normalized wave frequency, and c wave normal angle. The initial 5 subpackets are indicated with vertical lines. The long-duration subpackets (1, 2, and 5) exhibit smoothly rising frequency across their temporal extent while a step-like frequency plateau characterizes the shorter subpackets (3 and 4)
