LOL, have fun with those upper air launches. I hate launching above 30, forget 50+.

That is awesome, it is nice seeing the PVU surface. It was a pretty classic marine occlusion/dry swirl in that the vertical isentropic mass ascent was directly into the center of the low in response to the upper PV and the mass wind fields it supported (the divergent jet max). Pretty awesome.

That second pic is stunning, is that the top elevation on Cold Bay?

MtBlanc, I am glad to have you here on the forums. The first picture is absolutely stunning and gorgeous.

Nice classic marine occlusion and dry swirl in the GOA.

Ha, +SN = heavy snow. It is the surface observation term used by the surface observing system here. Light, moderate, and heavy are the discriminators used for precipitation rates. So, for instance, light snow would be -SN, moderate snow would simply be SN, and heavy snow would be +SN. Good question though. Thanks for all the nice pictures up there...should be a fun winter up there. Just curious, how did you end up there from France?

The GOA cyclone is massive, almost the size of the lower 48. Nothing terribly out of the ordinary for the GOA, but nice to see again. Bring on the baroclinic pain.

How did the 0Z Cold Bay sounding look tonite?

Polar Jet is about to drob the bomb in the Gulf of Alaska with a sub 960 bomb. GFS?EC bomb it out 25-30+ hpa in 24 hours.

Yes, from your location. It is a pretty sparsely populated area...not a lot of people have been there before. It would be neat to see images. I know a bit about the terrain/geography, but it would be neat to see images of the locale.

You should post some pictures of the area from up that way.

Welcome to the boards, I am glad to have a weather enthusiast from outside of the lower 48.

Gorgeous. Baroclinic bombs. I will disagree though, there is a fair bit of minor baroclinic pain going in Canada. Hudson Bay doom.

Nice post. Interesting features that stick out in the PABE sounding is the strong above mountain top inversion (around 850 hpa) which probably enhanced the trapped wave mode, but probably too high to incite strong downslope winds given the height of the range. I am assuming no major downslope winds? The other interesting feature is the model cross section which seems to be simulating a vertically propagating mode given the back tilt of the wave w/height. Do you guys have any higher res x-sections? I found the x-section tropopause uniquely flat...also neat to see how the model simulates (actually probably parameterizes) the dampening of the wave as it reaches the tropopause.

Nice maps. Got to love our awesome hygristors. Nice catch though, looks legit, and it makes sense with that type of deep tropopause that stratospheric mixing is occurring.

Those are bada** mtn waves.

Termination dust? I see some DCVA by CD3 progged by the EC/GFS for day 3.5+. Looks pinwheelish.

I am interested. I have been keeping up to date on weather up there lately, perhaps because of you and niumetgf, but also because of the extreme boredom of 600 dm subtropical death ridges.

Weatherdata is there to make money with respect to a very defined user base with different expectations and impacts. What is too bad is the poor comparison they use in their quote.

Glad you are back and ok Jomo

It is an incredibly fine line when it comes to tornadoes. Of course crying wolf all the time is not ok since it will inevitably result in the public simply ignoring the warning--but nobody wants to be the one who has no warning on a tornado that potentially kills people. That information needs to get out--and it is likely better that the FAR be a tad high since tor warnings are such a rare event overall.

An honest--question, what are the chances V2 would have secured its funding (or the amount of funding it eventually achieved) if it did not include "increased warning times" and "lived saved" in proposals?

There are a lot of options out there. I have a number of friends who graduated with a met degree then went into various engineering programs for their M.S. degrees--and they are successful and working in the engineering field. Doing this route would give you a chance to pursue your passion (meteorology) while setting you up for a different field should it not work out. Of course--this would also require that you get a M.S. Double majoring is possible, but that would be tough doing met/engineering at the same time. That is another possibility though.

Exactly. I love helping people and having a positive impact in peoples lives--even if they don't know it. Weather is an important job--and that is all anyone could ask for in a career field.
