West of Tropical Storm Beta. South of Oaxaca,MX.
Appears to be cold air diving over the Mountains from Beta's Northerly Winds. Best seen here. Not really apparent on any of the other filters.
Any ideas to what it might be called? See Attachment above.

That is a reflection of somewhat more stable air being channeled through the Chevala pass from the Bay of Campeche into the Gulf of Tehuantepec around the west side of Beta, definitely. It's a fairly common occurence with a tropical cyclone in the Gulf or western Caribbean and can sometimes help spin up a tropical system in the Pacific when there is an active wave along the ...i.e. it can give that extra little oomph/kick to a wave to help it develop if it was on the borderline beforehand.
But for now, though, you aren't going to see such a thing -- air in the Gulf is pretty dry & relatively cool and you're getting some stratocumulus development as a result of the temperature differential between the sea surface and near-surface air. Cool to watch, though.

Thanks Clark. At first glance I thought they had a Lava Lamp down there. Really was a strange site to see with Beta being so close.
