2013: ACE - ATL = 29.71 ; EPAC = 75.355 ; WPAC = 268.332

[euro6208]

I've been wondering what are the top 5 most ACE in a season for the wpac?

Highest are 2004, 1997, 1992, 1965 (and probably 1964). I'm not so sure.

1997 had an ACE of epic proportion...594.11...wow!

Does anyone know if this is the highest or is there even higher?

Some sources say that the WPAC ACE in 1965 was 595. We still need clarifications.

[xtyphooncyclonex]

Overall, Lekima and Francisco will add over 50 ACE, which the ACE in the WPAC is currently close to 90% of normal. The WPAC was severely deficit in ACE before, but because of our late BOOM (more than 5 typhoons on a single month), we are getting very close to our norm.


Atlantic has Lorenzo which is adding around 2 units and the EPAC has Raymond which will add over 10 ACE, bringing it closer to half of normal.

[HurrMark]

Per Policlimate, ACE with Lorenzo was 1.6575 (although it may turn out to be higher in post-analysis, since it seemed to stronger than 50 mph for a while). But for now, the average ACE for the year dropped from 2.45 to 2.38...over a full point below the anemic 1970 season.

North Atlantic

Eastern Pacific

Western Pacific

[euro6208]

WPAC driving the numbers up for the Northern Hemisphere accounting more than half of the ACE and higher than the entire Southern Hemisphere season...

[xtyphooncyclonex]

As of now, Francisco contributed 35.71 of our ACE, which was more than our total when it was July, very deficit. Lekima has contributed 22.1 units. Francisco and Lekima contributed over 55 of our ACE, and is already close to 90% of our normal activity. This ACE [55+] is very close to the overall ACE in the EPAC last month and is nearly double of the ACE in the Atlantic. The WPAC ACE currently stands at 217.395 [88% of Normal YTD].

The Eastern Pacific is currently relying on their first major, Raymond. Raymond has contributed 10.2475 of their ACE, but it is currently weakening west of Mexico. The EPAC ACE is currently at 67.5075 [50% of Normal YTD].

Tropical Storm Lorenzo was sheared, but retained its convective activity, and is already downgraded to a Low Pressure Area [20 kts]. It contributed 1.62 units in the North Atlantic ACE, which was forecast to be hyperactive but is severely deficit. The Atlantic ACE is only 28.55 [30% of Normal YTD].

North Atlantic

Eastern Pacific
61.8525

Western Pacific

Overall the WPAC was very backloaded. In the span of a few weeks it chewed up a large chunk of the deficit. In the end it's still going to end up near normal at the pace right now (MJO moving on) so it's not a crazy active season, but how quickly it made up for it was, for the ACE. The EPAC has been lackluster but has given us some decent canes and of course one major but still well below average. The Atlantic...well it's the Atlantic. Even if we do get a hurricane in Nov or December in the Carib it won't be enough to do much to yearly ACE. A bottom 10 finish is pretty much guaranteed, a bottom 5 finish is likely.

[cycloneye]

WPAC is poised to get a lot more ACE units with Haiyan.

EPAC is at 69.045 as Sonia goes away and WPAC is at 234.305.

Too bad EPAC will likely be finished. Amazing end to the season, with our first major hurricane arriving unexpectedly in late October! While the EPAC can give us surprises like this, you almost never get this from the Atlantic, unless the season has already been hyperactive. This is why I prefer EPAC, plus, there are less landfalls and the season starts earlier.

[xtyphooncyclonex]

I guess that after Haiyan, Podul [and Lingling hinted by the models], our ACE would be above 280 units!

[Ntxw]

Updated numbers from Dr. Ryan Maue's site for this week as of 11/6. WPAC continues to build and will be near average and possibly above average. Haiyan might turn out to be yet another Super Typhoon that eclipses the entire Atlantic season ACE wise yet again. Not much change in the other basins. Just a couple more weeks and calendar season of Atlantic will end. Realistically the Atlantic was done late Sept and may not add anymore values the rest of the way.

^That site listed Danas to have peaked at 90 knots though. I remember Danas strengthened to 125 knots near Okinawa. I don't know if 90 knots was just a typo or that 90 was used in computing for ACE.

[xtyphooncyclonex]

244.91 for the WPAC because Haiyan contributed already 13.765 units!

[cycloneye]

Including the November 8 21:00 UTC warning at 125kts,Haylan has increased the WPAC ACE to 260.82 units and individualy has produced 29.675 units.

[somethingfunny]

Haiyan has already produced more ACE than the entire Atlantic season has.

[hurricanes1234]

Haiyan has already produced more ACE than the entire Atlantic season has.

Amazing, just one super typhoon which the WPAC usually sees now and then has exceeded the entire Atlantic season of five months. Of course, Haiyan was extremely powerful, but in a normal season, it should take two or more of these to surpass the Atlantic, particularly at a late time like this where ACE units would normally be accumulating. Dud seasons like this are very rare, even 2006 and 2009 which had strong Pacific activity didn't see this puny number of named storms and hurricanes forming. Also, they saw 2 and 3 major hurricanes in 2006 and 2009 respectively, so even in hostile years there is at least one major hurricane. This year there were none, and it is quite inexplicable as to how and why these preventing factors came into play, and especially since preseasonal forecasts called for up to 6 major hurricanes because of unusually warm waters, which I believe were assessed to below-average temperatures being observed, in August. I could be wrong about anything here, so do not use it as official information.

West Pac is now 97% of normal ACE for the season through today.
