Quoting Canopus56 <canopus56@yahoo.com>:
I understand there is a similar effect tied to solar insolation on the redness of the Great Red Spot (GRS). The redness of the varies on a 30 year cycle tied to the solar cycle, but over the centuries, let's say since Cassini, Haley and Herschel, its redness has declined. I've forgotten the mechanism of action.
It's called "fading". I had a red Toyota LandCruiser that faded because I left it in the sun. Wax seemed to prolong the fading, but, it still faded none-the-less. I don't know, do you think a red car is more prone to fade than say, a white one? ;)
the more instense sunlight breaks up the red light chemical that accumulates in the upper Jovian atmosphere...
Probably the same thing...
