TC Bertha

[Chacor]

Which makes the best-track ACE 13.975 (operationally 14.11).

[HURAKAN]

Nice table, HURAKAN.

As always trying to impress using PowerPoint!!!

[RattleMan]

ACE for Bertha continues to go up,now 13.915,the season in total is at 14.3:

Code: Select all

Season total
Storm Type ACE (104 kt2)
01L (Arthur) Operational 0.3675
02L (Bertha) Operational 13.915
Total  14.2825

That's, again, wrong. Operationally it's 13.5475; best-track is 13.4125. Not 13.915.

I can confirm that:

The above was generated by a program that I wrote.

I wont follow wiki anymore as they are slightly behind.I will follow those tables with the updated ACE.

Kinda seems as if she's falling apart....like she does every single night.

Mostly lurking but it looks like dry air intrusion to me

[Derek Ortt]

its eyewall replacement of the type I have only seen in a model simulation where I had to do a LOT of fudging

[wxmann_91]

99.99% sure it's ERC.

It looks like it is going to have one big eye when she is through

[JonathanBelles]

Its gotta moon for an eye!

[HURAKAN]

Bertha never ceases to amaze.

[Sanibel]

Can't have an eye THAT big. The Atlantic could be changing it.

[MiamiensisWx]

Can't have an eye THAT big. The Atlantic could be changing it.

There have been numerous typhoons in the western Pacific that exhibited very large eyes after an ERC. They also featured similar intensities on the Saffir-Simpson Hurricane Scale to Bertha at the time.

I believe the bolded statement is false.

[HURAKAN]

New eye should be complete in the overnight hours and the storm could re-intensify again.

[Squarethecircle]

Wow, that's going to be a really large eye. I remember that Krosa last year had an eye of similar width in regards to the storm, but it hadn't even been a hurricane very long at all, and certainly hadn't had an EWRC.

Indeed. There are many many cases of annular typhoons with enormous eyes, and while they are much more common in the Pacific, the Atlantic has seen a few as well (most notably in recent years, Isabel).

1997's STY Winnie... https://metocph.nmci.navy.mil/jtwc/atcr ... 3/14ww.htm had an enormous eye once it became annular after and EWRC. So did 2000's Jelawat. You wanna talk a ginormously sick eye....try the 200NM diameter eye of 1960's Carmen on for size. Somewhere on line is a radar image of it...too lazy to look for it right now.

edit: grainy radar image can be found here: https://metocph.nmci.navy.mil/jtwc/atcr ... wnp/31.pdf

1974: Carmen

[AJC3]

1974: Carmen

Sandy, if that's from 1974, then it's the wrong Carmen (although, interestingly enough, it appears from that radar image that 1974's Carmen may have had a concentric double eye structure!)
