Les Cowley at
Atmospheric Optics has something spectacular on his
website all the time. It's one of my first internet stops in the morning
to see what fantastic image is posted there. Sunday morning he had a
photograph of a mirage taken from Vancouver Island looking out to the
Straits of Juan de Fuca. Here's a
link to it. Go take a look, and then come back and I'll tell you why it blew my mind.

There's an arrow pointing to what Moss Landing usually looks like on a cloudy day across the bay. Not zoomed in at all. |
Here are two views of Moss Landing. The above image is what we usually see from the beach house. The image below is one I found on the internet. It gives you a better idea of what Moss Landing typically looks like.
Back
in May, Roger and I went to the beach house in Capitola to
celebrate my birthday with my twin brother. The three of us went for a
walk and looked out across Monterey Bay and saw this.
The smoke stacks across the bay are the
Moss Landing Power Plant.
Those stacks are visible throughout the Monterey Bay area. They are
definitely a landmark. On this day they appeared half-way covered by a
fog bank or something. My brother told me he had seen them like this a
number of times. Dully reflective and strangely optical. I was
intrigued, but not excited. The above photo was taken at noon. At 12:25
it looked like this.
Click
on the image. That's a mirage. I didn't know that's what we were
looking at until I read Les Cowley's site Sunday morning. I was glad I
had saved these images even though they made no sense to me. I'm still
not sure what kind of mirage this is, and I plan to write Les to find
out. When I went back to my photo archives I found another image taken
from a slightly different perspective.
Here's a close up of that.
I
can't begin to understand how this image is possible. Seriously. What
are we looking at here? I have no idea. But that's what we saw, and I'm
going to embark on a journey of enlightenment to find out. I'll keep you
posted.
Here is Les Cowley's response:
"Your mirage is a superior type, so called because the extra images are above the object being miraged. Air normally gets cooler with increasing height. When there is a cold ocean current the air near to the waves gets cooled and there is a temperature inversion - cool air below warmer. In California in some months it is exacerbated by warm air coming off the land and layering above the cool ocean air. Light gets refracted as it crosses the temperature gradients of the inversion and forms the mirage.
At Santa Cruz you have an inverted image of the coastline and buildings above the horizon. The inversion layer does not extend to the height of the chimneys and so they poke out from the mirage apparently unaffected."
He wrote that there is a hint of a Fata Morgana as well.
He also sent a
link to another photo on his website. I highly recommend that you take a look.
