What orientation of Bz (B sub z) increases the likelihood that charged particles from the Sun will cause disturbed conditions?
Pick an answer to check it.
Answer: A. Southward
A southward Bz opposes Earth's northward field, letting solar wind particles couple in and cause geomagnetic storms. A northward Bz helps keep conditions quiet.
Tip: Bz south = storm risk.
