Chris, I take it the inverse does not hold true? For example, last November featured a respectable -AO. After that, IIRC, it bounced around in December for a bit and then shot through the roof.
That's nuts! You have to wonder what it looks like once it's rolled forward (with shortening wavelengths, etc.).
Thanks for finding these! I hate tossing '95 out there because it stirs up weenieism. I didn't realize that '95 had such low heights in the GOA and up top. NE PAC warm blob was sorta there though.
For comparison, does anybody have a 500mb composite for October 1995? And maybe a global SST map? Just curious since that also was an active hurricane season + Niña autumn following a Niño, correct?
::Scratches head::
This year's Sept./Oct. composite actually seems directly opposite to how Niña's typically behave in Canada and the NATL too. Do we know why? And are we going to wait around all winter for a Niña atmospheric "coupling" (hope I'm using the term correctly) like we did last year with the Niño?
Yeah that was my first thought when I looked today. Can anyone explain the conservative LF intensity forecasts? I can see the low OHC in the northern gulf inducing some weakening before landfall, but what's stopping ζ from just taking off in the meantime?
Yes we learned this hard lesson last year. Is there any evidence that the converse produces a better result for us (i.e., a tendency for the MJO to hang around in the colder phases)?
Are either of you able or willing to speculate what significance (if any) an opposite IOD state at this time might hold for this coming fall and winter?
Where did it stand at this time last year? Trying to figure out if it’s going to toss a wrench into our upcoming winter’s pattern like it did last year.
Or the Hazel-type scenario (assuming you’re not talking about a purely-tropical cyclone and you’re focusing strictly on winds). I know that the winds here were intense with that one, but did she have a dry eastern side as well?
