I see the same striping that Art sees.  For those not seeing the broad
stripes, do a histogram equalization (optional - just makes the effect much
more obvious)  and look at the separate color channels.  No stripes are
visible in the red or green channels but they are quite visible in the blue.
My first impression was that the stripes were due to saturation of the
bright weather vane but I don't think this one image is enough to determine
the real cause.  They are definitely not JPEG artifacts.
