Bering Sea BOMB

Recommended Posts

Just as a side note figured a few may like watching this storm, even if it's far away from the lower 48.

My first storm up here which wasn't as low of a MSLP (was 954ish) had 115MPH measured in Dutch Harbor with cargo containers blown into the sea from the docks and the Wildlife Troopers measured 164 KTS (yes I verified it twice with him making sure it was KTS and not MPH. Measured by a ship just off shore near channeled terrain). It wouldn't surprise me if the ANC Forecast Office hoists HURRICANE WIND WARNINGS later today.

Now that I have the upper air test out of the way and am getting the hang of intern duties, I will have more time to actually pay attention to the current wx. I've been out of the loop for a while now...AK as well as the CONUS. I can't wait to see how this plays out.

Bevis....I believe I talked to you on easternuswx....my SN was lawsonwx... you went to NIU right? I'm up in Anchorage now as a Met Intern!

Has a classic upper height field look with extreme bombs. Also note how the IPV max/dynamic tropopause wraps up as the upper level cold front descends towards the surface. This rapidly increases the horizontal thermal gradient in the vertical--hint hint. In other words--this increases the jet level winds.

post-999-0-44905500-1302061676.png

In other words--intense PV anomalies within the flow create their own jet streaks as the atmosphere responds to an imbalance (the upper level front interacting with a low level baro zone). The atmosphere responds by creating an ageostrophic divergent jet stream and this sets in motion positive feedback cyclogenesis/self development. This is why intense bombing storms typically have coupled jet streaks--just as this one here does as well. In other words--coupled jet streaks are a response to a deep and intense IPV max. IPV FTW.

Note the massive amount of jet divergence and the classic "V" cloud pattern on the inner portion of the curved jet as the low level flow within the warm conveyor belt rises rapidly into the divergent portion of the ageostrophic jet circulation. This is deep cyclogenesis.

Yep...good to hear from you again. I did go to NIU...met degree in 1995.

Congrats on the job in Anchorage! Did you fly up there? Or, did you drive the Alaska Highway?

Good stuff...just amazing.

What are you expecting in Cold Bay? How do you like life there?

Hey beavis....life is good and it's beautiful. I will post pics later. The tundra/grass, wild flowers, strawberries, and blueberries haven't blossomed yet and it's still nice. I have a view of mountains or volcanoes out of every window, a nice sized house, and a view of the bay from my master bedroom and dining room windows. I'll respond more later as it has been a busy day here. As for what we're expecting....HURRICANE FORE WIND WARNINGS and STORM WARNINGS are already issued for all of our marine zones, and HIGH WIND WARNINGS. Below is our Zone Forecasts.

Good to hear from you Patrick and hope you are getting situated in your new position. That is some intense storm. Keep us informed of your thoughts to how storms might affect us down here in the lower 48 and share your observations from up there. Tom Skilling loves to talk about Alaska.

Thanks....Winds were only 46KT last ob but during balloon launch winds "were kind enough" to pick up for me.
