EX TD10 Recon Reports

[WindRunner]

I look at two of them: the second 3-digit number (max 30-sec sustained wind) and the last 3-digit set of numbers (max 10? sec wind speed)
You can see the time in zulu on the front along with the cordinates. That's about all I use, I'm not sure about where the pressure is, though.


I'd like to know where the mini-obs are coming from, I can't seem to find them on any of the recon sites.

[weatherwoman]

please tell me that they have not actually sent a plane into that mess, there is nothing there it is sheered all to pieces

[djones65]

Wow! They are finding lots of southwesterly winds!
That surprises me...
They have been traveling almost due south along longitude 62W and found easterly winds then northeasterly winds then northerly winds then west, southwest and then south southwesterly.... The winds are only 8 to 14 knots though... <smile> but still indicative of a low pressure area....

Perhaps farther east they will find stronger winds....

[clfenwi]

Great lines of numbers. But what do they mean? What are they telling us???

Time / Position / Altimter / Pressure altitude / D-value / wind direction in degrees / wind speed in knots (30 sec avg) / temp / dewpoint / wind speed (10 second average) / radar altitude / If there are any '1's in the last column, then the particular value is considered 'suspect'.

I wholeheartedly disagree...the system is within "striking distance" of land, it has shown persistent convection throughout the day, it shows cyclonic turning at some level of the atmosphere, it has good curvature and model support for continued growth...If the only time they sent in a plane was when a system was already classifiable, we'd have a lot of unprepared people getting hit with storms that "suddenly" pop up and strike with little warning. Regardless of their findings today, I applaud the NHC for sending a plane out.

this system has been a TD for the past couple of days; however, it seems quite clear that it has now dissipated and is a weak tropical wave. Atmospheric conditions do not favor further development

They sent the plane out when it look better early this morning. Not it has detoriated since than. They made the right choice at time to send it out. It's hard to tell if it would keep up organization all day.

Yep, I haven't been able to locate that LLC today. And those westerly winds were up above 20,000 ft, not at the surface. So far, the plane appears to have found SE-SSE winds at 12-22 kts in the lower levels.
