Atlantic Tropical Action 2012 - Part I

Meh. I wouldn't not worry too much regarding the upcoming season on February 21st. Quality over quantity. I strongly suspect we won't see a Don type storm 'dry up' this season... ;)

One decent Charley storm into the U-Tube paradise of Florida, flat, good roads, palm trees, and one solid hurricane (doesn't even need to be a major) landfalling 50 miles either side of NYC, and I'll call it a success.

I'd like one solid high end tropical storm locally, one that won't damage Summer homes, but provide action on Steve's KHOU-TV 11 weather forum, and maybe provide an excuse to miss work, but if it doesn't happen, I'll be ok.

I'll be ok with just a Florida major or a NYC anycane, but obviously, both would be better.

monthly AMO is actually negative at the moment. Obviously that doesn't mean all that much since it has been negative during the early spring in 4 separate years in the 1995-Present regime. I don't have high hopes for a mariad of activity either, but I still hope we can get a couple nice majors.

You're going to be back in the BM for the season?

Here is the forecast june/august predicting well above pressures just about basin wide. (Not pretty) Just takes one as always.

Just for comparison purposes here is what it forcasted last season at peak around the same time frame.

Uh... you do realize you just compared a June-July-August time period to a September-October-November one, right?

That's not comparable... at all.

I was looking at the thread and i noticed the much higher than normal pressures in the eastern pacific last season, yet that season featured 10 hurricanes and 6 majors. the atlantic had a whole lot of sheared messes the last 2 years. i would be happy to have last seasons east pac season in the atlantic this year.

:facepalm:

Please remember *when* the El Nino developed in 2004. Thanks.

Your dislike of me and need to post face palms aside, please use your vastly greater knowledge to tell me why it matters, if the ENSO was positive during the season peak, why it matters whether it was already established or developing.

Besides annoyance at the never ending face palms, I'm actually curious as to whether the change of ENSO with time is a factor of importance of the same order of magnitude as the value of the ENSO. I assume you'd know.

The way the past few seasons have gone with most storms recurving away from the US i've just about lost hope for any action near home. Maybe we'll get a repeat of 2004 with those once in lifetime favorable steering. Just pure luck the way i see it in terms of were the long wave position is when a TC makes a run at united states. As others have mentioned even if el nino developes which again seems pretty likely in my opinion we can still see considerable development.

Dade County (along with Palm Beach, Collier and Monroe Counties) has the highest return period for major hurricanes in the entire country, but it's still only once every ten years or so.

Masters has a doctorate in "pollution meteorology". Before that, he was HRD and flew into Gilbert. And I did Wunderground years before I heard of AmWx.

What does any of that have to do with his poor use of statistics here? In order to find the expected value of numbers in a neutral year, you should either throw out the outlier or take the median. A straight arithmetic mean is not robust to outliers and certainly not with a sample size of 5.

FWIW, taking out the high/low outliers in each data set gives you a mean (not a sample size that one can take to the bank since it's just three years in each bucket) of:

Nina: 14.7, 8, 2.7

Nada: 15.7, 8, 4

Nino: 10.3, 4, 2

'05 really skews the data big time...

From CPC's weekly update..

Climate Prediction Center 2/21/12 Weekly update

All the ENSO regions warmed sustancially with Nino 3.4 up to -0.6C,warmer than the -1.0C that last week's update brought. In fact,Nino 1-2 close to South America is now in positive territory (+0.9C) This shows how La Nina is fading fast and Neutral ENSO will come in short order. The big question is if is going to warm even more and more to jump towards El Nino in a hurry.

I've grown to not care too much about seasonal predictions.

1. They're often not terribly accurate.

2. Even active seasons can be craptastic in terms of quality systems.

3. Even active seasons can be craptastic in terms of quality landfalls.

4. Some of the hawtest landfalls ever have happened in craptastic seasons (i.e., 1977, 1992).

5. There's always the EPAC-- the perpetual insurance policy for crappy NATL seasons.

So this hand-wringing over the ENSO state in three months is a big whatevz to me.
