Interesting feature at 10N and 50W early this am

#1 Postby **Frank P** » Sat Aug 06, 2005 2:04 am

noticed the burst convection SW of TD9 at ~10N and 50W... it has more convection than TD9 and almost hints of a rotation on the IR loop... actually it looks more impressive than TD9 at the moment, yes its awfully low to the south but it looks to be moving off to the wnw aiming at the southern windward islands about 800 miles away

Well, ANYTHING'S got to be better than watching TD9 and an on-again, off-again northern GOM LLC.

BTW - You gonna stay up and watch the shuttle?

It was hard enough for me to watch the launch being in the shuttle engine testing business.... you know the time its going to be over our area?

sorry I didn't open your link... got it

I think I might get up and watch it if I can .... with fingers crossed

I'm going fishing (assuming I wake up!!) at about 5, so I'm hoping I get to see it. Too bad they changed the re-entry trajectory for landing since Columbia... It used to be very cool - IMHO - to watch it fly across our skyline, then run inside and watch it on TV as it landed a few moments later at Kennedy!! Apparently, that angle for re-entry will never be used again...

Yeah, I can only imagine how that must feel for y'all. Talk about stress, anxiety, anticipation, dread, and hope all rolled into one emotion!! Wow...

I've been in the shuttle main engine testing business for a long time and we never ever thought we'd loose a shuttle on re-entry... we were always more concerned with the liftoff and the solids.... times have certainly changed... there is great risk with great accomplishments..... hopefully they will have a flawless landing...

WOW in that link if oyu set the speed as high as it goes and you look at the windward Islands you can see a huge circulation

A very personal feeling for you, I'm sure, whenever a mission is underway. I'll second your hope for a flawless landing...

Yeah, the pucker pressure is way up there during launch... and now during landing as well...

Hope you catch some fish today... good luck.

i've been working late in the office and had the loop on in the background - i had been wondering if i was the only one seeing it. you know, like maybe i've been up too long.
:eek:

i really don't like the looks of it. wonder if it'll still be there when i get up tomorrow?

Maybe something to watch. Hey maybe I will not go to sleep afterall. I know I will pay for it tomorrow though.

CENTRAL ATLC TROPICAL WAVE IS ALONG 48W/49W S OF 17N MOVING W
10-15 KT. CURVATURE NOTED IN THE LOW/MID-LEVEL CLOUD FIELD IS
USED TO POSITION THE WAVE ALONG WITH TSTMS IN THE ITCZ.
MOISTURE ASSOCIATED WITH THIS WAVE SHOULD MOVE INTO THE WINDWARD
ISLANDS LATE SUN...OVERSPREADING THE REST OF THE LESSER ANTILLES
ON MON. WIDELY SCATTERED MODERATE CONVECTION IS FROM 8N-10.5N
BETWEEN 45W-50W.

From the 8:05 AM Discussion from TPC.

Off topic a bit: What is that area that looks to have spun up off the east coast? Am I seeing that right?

#14 Postby **linkerweather** » Sat Aug 06, 2005 7:26 am

Nothing really spinning there, just looks like an area of convergence to me.

#15 Postby **Lowpressure** » Sat Aug 06, 2005 8:23 am

It is a stationary frontal boundry hung up over central Virginia per LWX. I can tell you it hammered here in Fredericksburg last night for a while, incredible lightning.

The wave SW of TD9 has a few "spins" associated with it this afternoon.

Frank I am curious about something. I am sure that someone around NASA had to have known that an extremely sStrong solar windshock occurred at the exact same moment that Columbia was entering the earth's atmosphere. I remember it precisely an ACE's one minute data ...which I have shows this.

This windshock was about 100 km/sec or stronger....Solar winds rose quickly from Low 400's to 700 or there abouts... Was this ever given consideration as to it enhancing the heat on it's tiles. We really do not know the physics of what happens up above us during one of these events. Joule heating etc...

I mean the tether experiment years ago showed us that we do not understand certain things. I have no idea if you know but I have always been curious about whether this was even considered.

SOHO's one hour data shows how the solar wind increased around 2/1/13z. The ACE data that I have shows what I am talking about when it came apart etc...

The solar wind speed is the first data column on the left ....listed under Speed...three digit number

Jim, in all my readings on the Columbia investigation I did not come across this issue you mention, albeit quite interesting.. however, that doesn't mean the Board of Investigation did not address it...

I do know this, any breach of the shuttles protective re-entry heat shield, under even nominal re-enty environmental conditions is catastrophic... you read data on the spikes in the temp measurements during descent as they start to detect the breach in various sections of the bottom of the shuttle (actually the initial penetration was on the leading edge of the shuttle's wing) and it send chills down your spine, and it didn't take all that long to go catastrophic either...

once the re-entry heat penetrated the shield for all practical purposes the shuttle was lost... the shuttle is a very sensitive flying machine and any violations of its aerodynamics is also catastrophic... this is not my area of expertise by any means as I'm in the engine testing business (I'm the Safety Administrator for Boeing Rocketdyne, which was just bought this week by UTC's Pratt & Whitney, now we will be called Pratt & Whitney, Rocketdyne)

At Stennis we don't launch em, we just make sure they can run as advertised... and so far the liquid propellant main engines (SSME) has performed pretty good during the shuttle program...

I see a well defined LLC at 13 north/48 west. It reminds me of tropical storm Emily of 1999 with Cindy(9) moving to its north.

Would it be cool if that formed some convection to become a depression. Even so I don't think it will be upgraded.

Nimbus · #20 Postby **Nimbus** » Sun Aug 07, 2005 6:04 am

Convection is flaring near 17N this morning and I don't see much shear.
