Why Evolution is True is a blog written by Jerry Coyne, centered on evolution and biology but also dealing with diverse topics like politics, culture, and cats.
The explanation given at the link and on Wikipedia indicates that Chinook or Foehn winds are associated with the lee slope of a mountain range. Calgary is a good deal closer to the Rockies than Chicago so I wondered how far from the mountain the effect persists? Or is there an alternative explanation for the cloud featured in this picture?
It may be comparable in it’s proximate mechanism (it definitely looks like a Chinook arch), but a Chinook needs mountains for diabetic compression (not for nothing it is called ‘bergwind’ here). I would be surprised if a Chinook would persist 1500-.2000 km from it’s origins.
Just a guess…I’m pretty sure this effect can be created by other weather conditions. Perhaps just pronounced layering and stable, smooth air masses moving just so. Chicago is on the w-sw edge of Lake Michigan, which is huge. I wouldn’t be surprised it the lake had something to do with this configuration.
The caption could be – There are 3 million stories in the city. Ever think about how many TV shows of the past were centered in Chicago. Some I knew well such as Crime Story, with Dennis Farina and the theme song Runaway by Del Shannon. Some I had no idea were Chicago such as Married with Children and M Squad.

If it wouldn’t be any bother/worry: how far up was that shot taken from?
I like your photos of the Chicago skyline.
Yes, they are like art!
That looks really good on a large monitor. The colors in the buildings are so subtle.
I love the skyline shots from your “crib”.
Lovely photos..Have not seen suck a perfect chinook arch since leaving the foothills many years ago.
I didn’t know what a Chinook arch was, but I looked it up and learned something:

Thanks!
