Re: The northern and southern lights are different. Here’s why Then the article completely and utterly fails to tell us or show us why.

They do seem to explain, but in a very convoluted way. A diagram or other visual would certainly have helped.

"it made sense to assume the atmospheric displays in each hemisphere would mirror each other. Advances in Earth imaging technology overturned this way of thinking in 2009, when scientists observed simultaneous aurorae drifting across the poles in patterns that didn’t match up.

The study examined images of 10 asymmetric aurorae taken simultaneously from both poles and related changes in the aurorae to changes in Earth’s magnetotail, a windsocklike extension of Earth’s magnetic field.

The researchers found that when solar wind approaches Earth from an east-west direction, it creates uneven pressure on Earth’s magnetotail and tilts it toward the side of the planet shrouded in darkness. That tilt causes the idiosyncrasies of shape and location of the northern and southern lights"

Believe it or not, a type of aurora borealis can be seen infrequently in the western desert of the Sudan.

That’s what gets me, no graphic? The problem here is that the author doesn’t understand any of this, either. He’s trying to interpret a press release from some scientific outlet (probably a university) and doing a crappy job of it.
