Good morning. I realize that, other than this, I am often Missing In Action these days. I want to apologize. I'm simply fizzled and frazzled to the poitn where nothing I type makes sense beyond, "Wow, I hope you feel better" and I amd starting to thinkt here should be a shorthand for that. We have WTF FML TTYL LOL and all the rest. Quick, someone under 25 make a hip shortcut for saying "That sucks, hope you feel better"!
I have a dentist appointment. Ugh. You ever just *know* the dentist appointment will mean you end up with a something-ache? Yeah. That kind of day here. The temps are swinging back to "normal" on their way to "whoa, stop, tooooo warmmm!" A weather front i sready to pounce. Or not. Maybe it'll rain. Or not. Spin the wheel, place your bets, it's weather roulette!
I complain only tongue-in-cheek. Where I grew up, snow was once seen on July 4, and was still around at Easter, and sometimes showed up at Halloween, and you'd be wearing shorts at 45*F b/c to you, that was nice and toasty. At 70*F (20*C) people turned on air conditioning. (If they had it.)
Not quite Labrador, Canada, where it is said you can have all four seasons in one day. Yes. You can. Unfortunately, the "spring" part doesn't get you any flowers, and you miss the happy summery green, but the temps? Craziness.
The eponymous Labrador Current, which is the cold south-flowing version fo the Gulf Stream current, is with that Gulf Stream, a huge weather-maker in the eastern US, particular the coastal regions, and can even end up affecting Europe. See, all that warm water from the Gulf of Mexico and Caribbean pushes north... usually not too much further north than the Outer Banks of North Carolina. If you ever look at a US map, you can see why. That part sticks out like a "nose", and betwween that and the shoals and so forth...
Well, right about there, the GUlf Stream splits up. It does some awesome weirdness in the Atlantic, on thermal imaging (seriously, watching that year to year is kinda fun, like watching ink dropped in water, the way it swirls). The warmth shoots northeast and spirals around itself sometimes, and shoves warmth both towards Europe (you're welcome) and then southwest back toward northwestern Africa. That latter bit,t he Canary Current, is wind-driven. The Nroth Atlantic Drift of the Gulf Stream? Nope. Big old "push". What's weird is, you can see on thermal images where the current diffuses (yes, diffuses, not defuses like a bomb) when it hits the Mid-Atlantic Ridge under the ocean. Then it just sort of "waves" or emanates toward western Europe, while the colder bit dips north...
Where it's recirculated into the Greenland current, which then flows into the Labrador Current.
The Labrador current's southernmost extent is usually around those same Outer Banks of North Carolina, whic is one reason why all those winter nor-easter coastal storms tend to form there. Competing temperature masses.
Usually, however, you see the power of the Labrador Current start to wane around Cape Cod, Massachusetts (another land nose, so to speak, but also a convenient landmark, really), or more accurately, offshore on the Georges Bank. (Fishing grounds. Why? Currents changing equals changing fish and nutrients and so on.) The Georges Bank extends northward to Nova Scotia.
But why doesn't the Labrador Current dissipate into the North Atlantic? Why does it turn southwestward and hug the coast of the continent? Is it hte power of the Gulf Stream pushing up and then northeast into its "drift" to Europe? Newfoundland, canada, is a pretty good "nose" into the Atlantic itself, yet the Labrador Current snaps right around it.
Turns out there's a reallllly weird effect of earth's rotation on oceans. The western sides of both the Atlantic and Pacific oceans have swift, narrow powerful bands of currents --- the eastern sides, slower and more diffuse currents. These eastern boundary currents (or the ones on western shores of continents) are also more shallow. Yep, both hemisphers (north an dsouth).
These currents end up causing "ocean gyres", or major ocean circulations. There's five biggies. Understandably,t he North Atlantic and South Atlantic are two, as are the North Pacific and South Pacific, but there's also a biggie in the INdian Ocean.
That one in the Indian Ocean reverses direction and gives South Asia its monsoons. Freaky, but true. The other four biggies do not do that.
For the record, the big western boundary current off Asia is called the Kuroshio, or Japan current. The Agulhas is the Indian Ocean's against southern Africa. No idea what the others are named, but those three I found.
So, anyway, yeah. Warm, cold, water, air, wind, weather, ouch.
Blessed day toa ll. Off to face dental cleanings, laundry piles, and so forth. Onward! Courage! Energy! .... chocolate....
