Re: ENSO Updates
Interesting. 2014 could end up like 2012, where we saw quite a few major hurricanes in EPAC. Excited to see powerful fishes!

Re: ENSO Updates
Recent signs hint of ENSO turning warm and already models are picking up that by forecasting warming by late Spring or early Summer. Here is the CFSv2 model.

Re: ENSO Updates
Then 2014 might be fairly active.

Re: ENSO Updates
I think we will get a better idea if a Nino is coming by March. A lot of variables can change through winter, this isn't a good time for models to predict ENSO.

Re: ENSO: CPC update at 11/11/13=Nino 3.4 up to 0.0C
Climate Prediction Center update of 11/11/13
Nino 3.4 warmed up to 0.0C. Let's see what happens with ENSO in the next few weeks and months to see if El Nino comes after a few years being absent or Neutral prevails for one more year.

I wouldn't call 2012 an EN year because Nino 3.4 rapidly went cooler by December after a short period within EN level. This year is clearly cool neutral. I think the chance of El Nino increases as we've had more years coming without a true El Nino.
Last 2009, activity in the WPAC was not very high for an ACTUAL EL NIÑO, with 22 tropical storms which 11 became typhoons.
Last year [2012], was more active, with 25 tropical storms which 14 became typhoons.
I can't even believe that it was El Nino last 2009. EPAC only had 8 canes. WPAC ACE was only 266 compared to 2012's ACE - 300.
Was last year warm neutral?
Those are 10 min average totals...
here are the storms totals for both years (1 min)
2009- 23 Tropical Storms 15 Typhoons 7 Major Typhoons- 266
2012- 25 Tropical Storms 16 Typhoons 10 Major Typhoons- 300
The el nino in 2009 was more of an modoki type so maybe that explains the slow activity in the EPAC.
2009 PHS was anything but slow. 20 storms is tied for highiest since 1992.

Re: ENSO: CPC update at 11/11/13=Nino 3.4 up to 0.0C
Very interesting - 2014 is trending towards an El Niño or at least warm neutral. I wonder, does this mean we see more fish storms far from land like Gil and Henriette this year? Or does this mean more storms that affect landmasses?

Both in a sense. Less weak storms off of Baja, storms that affect land are stronger.

Re: ENSO Updates
The November update of the ENSO models continue to forecast Neutral conditions thru the 2014 Spring.

2013 brought an unusually high number of storms in the West Pacific. Isn't this the same of what happened during 1996?

i'm not sure but it's about time the wpac delivered a true wpac season compared to the last few years. Many people don't realize how active the wpac can be. Seasons like this is very common and more active seasons have been recorded...

The early 90's saw high levels of activity with an extraordinary end to the 1997 season. This season is nothing compared to those years.

Maybe next year will really be an active Pacific season! We've reached Warm Neutral.

Re: ENSO Updates
The Aussies continue to forecast Neutral ENSO at least thru the 2014 Northern Hemisphere Spring.
ENSO-neutral conditions persist in the tropical Pacific
Issued on Tuesday 3 December 2013 | Product Code IDCKGEWWOO
The El Niño-Southern Oscillation (ENSO) remains neutral, with the majority of atmospheric and oceanic indicators close to their long-term average. The Southern Oscillation Index (SOI) has risen steeply over the past two weeks; this is partially an effect of monsoon activity over Darwin. International climate models indicate that the tropical Pacific will remain neutral at least through to the austral autumn.
POAMA model.

I'm sticking with the possibility that next year could be relatively active in EPAC because of warm neutral. I think it will have a much higher ACE than this year in that basin. Let's see if SSTs warm some more.

Re: ENSO Updates
Climate Prediction Center 12/5/13 update
Neutral thru the 2014 summer but they add that El Nino has increasing chances to develop by that time.
The majority of model forecasts indicate that ENSO-neutral (Niño-3.4 index between -0.5oC and 0.5oC) will persist into the Northern Hemisphere summer 2014. While current forecast probabilities are still greatest for ENSO-neutral by mid-summer, there is an increasing chance for the development of El Niño.
