The convection rolls shall be oriented exactly NS at 32°N and 32°S. Is there any indication for this? Let us have a quick look. What about these two locations:
This surely can not be closer to NS.
Neither can this.
This means we can find very prominent features at 32°N and 32°S aligned NS, the same way as the convection rolls underneath.
Can we find something more special at the 32nd latitudes?
