is this a map of prevailing pressure differentials due to standing waves in the jet stream (ripples in the bed)?? or???

@meetar artifacts of the analysis? I would think jet-related waves would be more N-S.

@sgillies right?? maybe some kind of transverse wave related to js-driven convection?

@meetar @sgillies I’ll bet $1 it’s an artifact of the zone borders. If every zone moves by half a zone width, you get stripes half a zone wide. They show up in the east because the climate is more spatially consistent there.

@vruba @sgillies okay that’s obviously it, but it’s still angled to ~align with the jet stream, which is professionally annoying.

@meetar @sgillies I think you’re right because every climate scheme seems to agree that there’s a slight twist to the latitudinal gradient of climate over the Eastern US: http://www.cec.org/north-american-environmental-atlas/climate-zones-of-north-america/

@vruba @sgillies probably has something to do with the ocean. and the sun.

@meetar @sgillies I think the sun is probably too far away to affect Tennessee.
