"Weather Bomb" Headed for Vancouver Island


We're not strangers to powerful squalls and extreme winds but what's heading for Vancouver Island over the next few days could be biblical.

Report authors note that the first storm is in the midst of an "explosive cyclogenesis, a drop in pressure of at least 24 millibars in 24 hours - qualifying it in popular parlance as a 'weather bomb." However, this system is expected to do "twice the amount of strengthening" needed to meet that definition.

"While this is the wet season for the west coast, and they are no stranger to strong lows at this time of year, two back-to-back powerhouse systems like these are certainly something to take note of," says Nadine Powell, a meteorologist at The Weather Network.

The storm will also be strengthened by the "remnants from a western Pacific typhoon," explain report authors, which will increase the amount of rainfall.

Low #2 will be stronger, belongs in the Bering Sea, but instead, it'll be southwest of Vancouver Island Sunday PM. It's unprecedented in terms of pressure. Still, lots of questions on the wind field, strongest just south of the centre, decays on approach - it's honestly weird.

Update:  This is weird.  When I awoke this morning everything outside was perfectly still. Not a leaf rustling.  Even the birds seem to be hunkering down in the cedars. There was blue sky but that's gone now. I have this feeling that this eerie stillness is about to change - real fast.

    We had the effects of an 'atmospheric river' in Vancouver, on Thanksgiving wknd.
    Now this!

    Funny, your post prompted me to google "undulating jet stream 2021" as I suspect it may be part of the picture here.

    The two top search results were
    https://www.carbonbrief.org/jet-stream-is-climate-change-causing-more-blocking-weather-events

    and then

    https://electroverse.net/the-changing-jet-stream-and-global-cooling/

    It seemed so appropriate for these BS times of "we present both sides and YOU decide" and the imminent death of empiricism.

      Hadley Cells and Rossby Waves, NPoV. Do you remember in 2013 when Calgary got its second "once a century" flooding in the span of just five years? That resulted from a torrential rainstorm that parked itself over the foothills for several days. Another example was the Atlanta Big Freeze.

      The following year it was Atlanta's turn for weird weather. An ice storm hit Georgia at the end of January. Traffic was stuck for days. At the same time residents of Barrow, Alaska were basking in low-60s temperatures. Rossby waves were bringing warm winds out of the south to the far north and Arctic winds down to Georgia. Today we're accustomed to winter heatwaves inside the Arctic Circle even in the 24-hour darkness of winter.

      Aren't you glad this is all a hoax?

Up in Smoke. 300 Sq. Mi. of Amazon Rainforest Lost Every Day.

Image
  The Amazon rainforest is disappearing at what should be an alarming rate. 312 sq. mi. or 808 sq. kms. every day. Over the past 30 years humans have destroyed a patch of the Amazon equal in area to the states of Texas and New Mexico . The Amazon – historically a great carbon absorber, since trees take in carbon dioxide and release oxygen – now releases more carbon than it stores, which adds to, rather helps to reduce, our global climate crisis. Deforestation rates decreased slightly from 2004 to 2012. But since then, they’re back on the rise, especially in the past couple of years, since Jair Bolsonaro became president of Brazil. In 2018, as Bolsonaro campaigned as a patriotic man of the people, scientists predicted that once the Amazon lost more than 25% of its tree cover, it would become a drier ecosystem, all because deforestation changes weather patterns (due to how trees respire), which in turn reduces rainfall. Furthermore, as the forest becomes fragmented, areas surrounded...

The Cognoscenti Syndrome

  There is a group of people I think of as the Cognoscenti, people who are well educated, very informed and of rapidly diminishing relevance. Their ranks include writers such as Chris Hedges and Glen Greenwald. These are people who have honed an almost Puritanical value system, readily finding fault in any direction. They are scathing in their attacks on Republicans and Democrats alike to the point where they become nihilists. They don't endorse. They prescribe. This is where they fail. They're unable to advocate for anything that might resonate with the public whose interests they argue are being trammeled. Donald Trump was bad but Joe Biden is scarcely better. This is where their elitism comes in.  74 million may have voted for Trump but, hey, they didn't know any better. The mob that stormed the Capitol. They were just victims of the system venting their frustrations. All the racism, bigotry, xenophobia, misogyny, white nationalism - inevitable side effects of their oppr...

Who Asks "Why?"

Every time there's a conflict between the Israelis and Palestinians, all we hear is 'why?'  Why, as in, whose fault is this? It's easier to affix blame if you can truncate the event. Pick a convenient start date, something recent. In this case we'll make it either the Israeli eviction of Arabs from Jerusalem or the scuffle that took place outside the mosque in response. If those don't work, let's go for Hamas launching unguided rockets into Israel. That's even better because it tags Hamas with the blame. The nice thing about this approach is you can just keep using it. It goes on and on, just as it has for the past half-century since the '67 war. You can even date this whole mess to the beginning of the occupation of the Palestinian territories. The Israelis are said to have called these periodic wars, "mowing the lawn." The idea is that, every now and then, you have to take these Arabs to the woodshed. And then you keep your powder dry unt...
