It looks like some of the shear it's been under from the south is starting to slow down a bit.

this probably sounds dumb, but how do they get those buoys to stay in that same location in such deep waters? are they anchored with a 3 mile long cable?

Matt,that is very old,from early this morning.No SSD estimates has been given this afternoon.

thunderstorms pulsing again. Man, I keep trying to pull myself away and come back in a couple of weeks, but these boards are so addicting, I just can't do it.!

They have divers assigned to them, the divers wear GPS devices and swim it back in place when it gets off course, good money if you can land the job. 8-)

The convection has increased a bit this afternoon over the low center.

Sanibel · #348 Postby **Sanibel** » Tue Aug 08, 2006 2:44 pm

That's why I've been telling you to watch for a center burst.

ConvergenceZone · #349 Postby **ConvergenceZone** » Tue Aug 08, 2006 2:49 pm

let's see if the burst can continue now and not fade away like the last TStorms did.

Hmmmm...

Fat Lady needs to exit stage right. :wink:

does not appear to have much in the way of banding... not all that impressive, IMO, unless it persists for 24 hours

well convection is a start, but let's see if it persists first.

Yeah we've seen this system have bursts of convection only to be sheared off. It's got to sustain convection for a while and improve it's upper lewel out flow and divergence.

right persistance as always key nothin to go crazy about but im hoping it has come back

#356 Postby **skysummit** » Tue Aug 08, 2006 2:57 pm

The convection is more of a "ball shape" this time. Maybe this is the one that gets going.

It was a ball shape this morning too. The only difference I see is that it seems to still be growing.

He's kidding you! The buoys are moored (attached to seabed). From NDBC:
http://www.ndbc.noaa.gov/mooredbuoy.shtml

... To assure optimum performance, a specific mooring design is produced based on hull type, location, and water depth. For example, a smaller buoy in shallow coastal waters may be moored using an all-chain mooring. On the other hand, a large discus buoy deployed in the deep ocean may require a combination of chain, nylon, and buoyant polypropylene materials designed for many years of service. Some deep ocean moorings have operated without failure for over 10 years.

41040, 41041 are NOMADs:

NOMAD buoys -- The 6-meter NOMAD is an aluminum-hulled, boat-shaped buoy which provides relatively high cost effectiveness and excellent long-term survivability in severe seas. These buoys are highly directional and have a quick rotational response. There have been no known capsizings of 6-meter NOMAD hulls. The relatively small size of the NOMAD allows for superb transportability via flatbed trailer, rail, or ship. Like the 3-meter discus, they are less likely to corrode and the magnetic effects on the compass are slight.

this blowup looks a bit healther than the last blowup of storms. We shall see.

#360 Postby **bvigal** » Tue Aug 08, 2006 3:10 pm

I have to agree. Looking at visible loop, this looks dead center over a circulation which appears just a few frames before.

By the way, anyone know what are these extra black model tracks?
