Nothing of interest showing at the moment.
I don't see the lenticular clouds that John suggested (it's
mid-morning as I look), but I've seen that sort of thing often enough
on well isolated hills to see Vesuvius as a very plausible location for
forming them too.
Yes, it eventually did appear to be that sort of a mechanism at work
this morning on Vesuvius, too. I'm not sure if it was precisely
lenticular clouds, but what was clearly visible on another cam (one in
Naples that was apparently somewhere approaching 90 degrees from the
Sorrento cam)was a "stream" of clouds going downwind from the top of the
cone. The wind, as John pointed out, and other conditions this morning
like humidity and instability were just right to get that continual
formation of clouds around the summit. Certainly it was happening faster
than I've seen such things happen at other times--must have been very
windy up there or the atmosphere very unstable. Due to the angle of the
Sorrento cam, I couldn't see the clouds downwind, and it surely did look
like a plume of some sort coming up; it appeared dark gray and I could
see it moving away from the volcano at times, which totally convinced me
it wasn't a lenticular cloud.
<blush> Hope I didn't get everybody excited. Well, back to my Italian
breakfast of /uovo sulla mia faccia/ (per Babelfish); it's quite a large
helping today.
