Haha! I loved the Carp Hunters, and Jack Sparrow. I was waiting for the carp hunters to have a Darwinian mishap though.

It has to do with the index of refraction of the atmosphere associated with temp. inversion.

Well, that was a piss poor explanation, so I pulled this from Wiki.

The reason for a green flash lies in refraction of light (as in a prism) in the atmosphere: light moves more slowly in the lower, denser air than in the thinner air above, so sunlight rays follow paths that curve slightly, in the same direction as the curvature of the Earth. Higher frequency light (green/blue) curves more than lower frequency light (red/orange), so green/blue rays from the upper limb of the setting sun remain visible after the red rays are obstructed by the curvature of the earth.

Green flashes are enhanced by mirage, which increase the density gradient in the atmosphere, and therefore increase refraction. A green flash is more likely to be seen in clear air, when more of the light from the setting sun reaches the observer without being scattered. We might expect to see a blue flash, but the blue is preferentially scattered out of our line of sight and remaining light ends up looking green.

With slight magnification a green rim on the top limb of the solar disk can be seen on most clear-day sunsets. However the flash or ray effects require a stronger layering of the atmosphere and a mirage which serves to magnify the green for a fraction of a second to a couple of seconds.

There are problems with the explanation of the cause of the green flash. The refractive index of air is 1.0003 compared with about 1.5 for glass, which means that a ray of light will suffer little refraction in the atmosphere, i.e. the ray will continue in almost the same direction as that before encountering the atmosphere. Further, there is the question of why the flash is of such a small area considering the size of the sun's image. There are many unanswered questions relating to this phenomenon.

Interesting is that air has an IOR of 1.0003. That is pretty goddamn close to no refraction at all. Those of us that look at the sky fight the effects of refraction in various way. Usually, it involves throwing money at glass with better refractive properties, but one of these days, someone will develop a tool that can marry the properties of fiber optics with that of the atmosphere, convergent lenses, and my eye.







That last sentence was supposed to be in parenthesis, but I lost my train of thought, and what I was talking about. Liquor-- god love it.
