If I am looking right the plane is climbing in altitud meaning the mission is over.Also the latitud is dropping meaning they are flying away from Helene.

[WindRunner]

They are not climbing in altitude. The third column is in feet and is directly related to the surface pressure, as they try to stay at a certain pressure level. All this increase in altitude indicates is a rising pressure, indicating that they are flying away from the center. If you look back to when they were near the eye, the altitude is around 4800ft.

And this is a NOAA jet, and therefore not exactly intended for low-level pentration as it did today, so this exit from the storm (however complete it may or may not be) indicates either an outer leg or an exit for synoptic survaillence.

NOAA Plane is close to the eye.They found 129kt wind.

[bjackrian]

That 129 kt looks like an abberation. I'm guessing it's not real, at least unless it's confirmed by other obs.

[artist]

doesn't the 1 in the end group of numbers where the 129 kts is reported mean it is suspect?
Seems I read that somewhere.

I thought the last three digits were the estimated rainfall rate in mm/hr (e.g., 10 mm/hr in this case). I was basing my comment on the abrupt lack of continuity in both wind speed and wind direction.

I found it.Yes,if it says 1 it is suspect so that 129kt is suspect.

Cycloneye, I think you're looking at the way to decode AF obs. If I'm reading the thread you linked correctly, NOAA obs have the last three digits as estimated precip rates, right?

I really wish they'd pick one standardized form for HDOBs!

[P.K.]

There is nothing on there saying it is suspect as far as I know. They are at approx 5km by the way.

[artist]

very confusing...

[cycloneye]

very confusing...

Definitly the AF obs are more easy to look at and to understand which columm is for what.The NOAA obs are more complicated.

[Thunder44]

Here's a map showing the flight and where they found that 129kt FL wind. I put a question mark next to it because I'm suspious of it. It's reported about 73 miles NE from the eyewall.

[Brent]

I would think that's suspicious being so far away from the eye.

[artist]

I guess they could have found a mini vortex there.

Well the 30 second reading is only 80kts, with the peak ten second value being 129kts. Also note that the SFMR estimate is only 46kts.

Thunder44,I see that a set is missing as the time is ahead from what it ended the previous set at 17:00z.

They are passing thru the eye now but the NOAA planes dont send Vortex Data Messages.
