I am so confused on how festoons appear on Jupiter. I believe that the changing of wind speed is the cause. Is this true? If not, can you give me some reference to read about this phenomenon?
hi reynan,
check out these references:

basically, there is a large amplitude vertical wave. when the wave brings air up, it forms clouds (the festoons). when it brings air down, it creates 5-micron hot spots, sometimes also called dark projections.
the actual shape of the festoons has not been modeled in detail, i don't think. but i would agree with you that it is related to change in wind speed (horizontal wind shear).
