[jinftl]

Nadine is the ACE gift that keeps on giving....Atlantic total now up to 94.5 as of this morning. Nadine will probably get the seasonal total very close to, if not past, 100. That would make the 2012 season from an ACE-perspective average...even if we have no other storms (average annual ACE in Atlantic from 1950 to 2009 is 101.6).

2012's ACE to date compared to total annual ACE for prior seasons of late:

2005 - 248
2004 - 225
1998 - 182
1999 - 177
2003 - 175
1996 - 166
2010 - 165
2008 - 144
2011 - 121
2000 - 116
2001 - 106
2012 so far - 94
2006 - 79
2007 - 72
2002 - 65
2009 - 51
1997 - 40

UPDATED:

Wpac ACE now up to 223.222 thanks to jelawat which produced a whopping 44.8825.....

What is the record for ACE by a single Atlantic storm that failed to get past Cat 1?

[cycloneye]

The North Atlantic ACE units reached the 100 mark thanks to Nadine and the brief Oscar.

100.065

Sandy ACE as of Sundays 5 AM advisory is 10.0225. Now the North Atlantic total is up to 118.9275.

[cycloneye]

Sandy got 12.4925 units and the North Atlantic has in total units 121.3975.

Son-Tinh contributed 9.9575

Season now up to 267.09

[OuterBanker]

I still think that 2012 will have the dubious award of the lowest ACE per storm though.

But we will remember it because of Issac and Sandy.

Leslie's and Michael's ace was nearly half the season and a total waste. It will skew the rest of the season's ace. We will not remember that as time goes by and they will give a wrong impression on the year. Proof that we should not judge a year based on the ACE index.

[JtSmarts]

Did 2012 surpass 2011's ACE?

Did 2012 surpass 2011's ACE?

Yes. 120.9525

And, your method would be...? So what if they cause half the season's ACE.

[cycloneye]

CrazyC83, I saw at Weatherunderground some people talking about about counting ACE for Subtropical systems in the future. I dont favor that.

That would actually be better IMO, since a lot of pre-satellite era storms are listed as tropical storms in HURDAT when they were likely subtropical in nature. However, they only classify them as tropical because they have no satellites to prove the structure. The earliest subtropical cyclones in HURDAT are from the mid-1960s.

If Sandy had made landfall before the satellite era (and the death toll would surely be deep in the thousands in that case), it would likely have been considered a hurricane at landfall with no satellites to show its interaction with the front.

The ACE numbers for the North Atlantic increased a little bit after the post season report of TS Florence came out. Is now at 122.975 units. We will see as the reports are released some changes up and down.

[TropicalAnalystwx13]

Did 2012 surpass 2011's ACE?

Yes. 120.9525

Well...it did for a while. But after going back and adding in the ACE for subtropical cyclones, the final 2011 ACE is 125.6325 units. The current ACE for 2012 stands just shy of 123 units.
