So very nice to get this kind of flight report & thanks Chuck. Jari's experience suggests there may have been "cycling" going on...which is easy to discern with a cloud field and conversely, impossible on a blue day unless there are hundreds of sensors (sailplanes) distributed over the area in question. You can see structure in the pattern of blue thermals when they first start forming, using special high-resolution radar (can see bugs too), due to variations in the index of refraction from water-vapor, since the first thermals are vertically-advecting (i.e. convecting) surface moisture. But once the convective field becomes well-established they are smeared out and individual thermals become invisible to the radar (incidentally, those first thermals look like mushrooms). |
Also wondering how today turned out? Tonight's sounding goes not-quite adiabatic up to ~ 6 K with a sharp inversion there, as well as a marked surface inversion from end-of-day cooling. Suggests it was weaker than Saturday and you had to work harder to stay up, in contrast to my update this morning. Did see from East Bethany some isolated patches of cu off to the south, they looked quite high, > 6 K.
Flying, sex, and drinking all quite self-rewarding (barring simultaneous indulgement), no guilt trip indicated!
: All indications were that it was going to be a
: great day per Dr Ray, XC Skies & Blips.
: It was a good day but not great. A blue day
: with no Cu. Being a cautious soul, I
: personally don't like to venture forth until
: I can get to 5,000 ft. With that in mind,
: it took me about 2 hours before I could
: crack 5,000 ft. with most of the time spent
: at about 4,000 feet. So I just wandered
: around the area within gliding distance of
: DSV. Jari ventured sout to Avoca and was
: rewarded with a climb to 8,000 ft and he
: proceeded down to Elmira from which he
: couldn't get away. Jari landed at Elmira
: and was retrieved via aerotow by Pete Neal.
: Dr Cline went North and got to 8,000 ft near
: the Mt. Morris dam. I wandered around the
: area keeping an eye out and listening to the
: preparations for a test winch launch at the
: end of the day by Jim Rizzo Esq. in the
: glider and Tom Roberts on the winch.
: Sadly, the winch did not co-operate and
: needs a carburator repair/rebuild. I did
: enjoy my non-stress flight of 4.1 hrs ala Dr
: Bernardis/Ironpants. Hoping to hear how
: everybody made out today, Sunday. Also
: found six pack of beer on my car seat on
: Saturday courtesy of Dr. Ray. Thanks Dr.
: Ray, but you don't really need to do that
: anymore. Flying is reward enough.
