You really dont get it, do you. The energy input should not be allowing the deep cooling. But then you do not understand how pressure gradients work.. The loss in energy input allows a cold low to over power the weaker high pressures ...
Ha ha ha ha ... like you know what a gradient is ... I'm going to assume you mean the horizontal pressure gradient, because that's the only way any of the rest of this post makes any sense, though that's a stretch ... if you look at the pretty picture in post #16, you'll see a big capital "L" ... that's the center of what's called a "cyclone" ... this cyclone is spewing energy into the environment as long as it's drawing in moist air ... that's right, that "L" is a concentration of energy, a little in temperature, but mostly to maintain the profoundly non-equilibrium state of "low pressure" and torque to spin the cyclone ...
Now let's look at Peter Sinks itself ... these temperatures are being recorded at the bottom of a crater ... a hole in the ground ... with a fairly steep rim ... it fills up with bitterly cold and denser air and over the top of this crater we have warmer and more buoyant air flowing horizontally ... cold air below, warm air above creates what folks in the trade call a "temperature inversion" ... this completely inhibits
vertical air movement ... cold air stays below getting colder, warm air stays above getting warmer ... go ahead and burn a few tires on the crater floor, see how the crater fills up with smoke no matter the winds aloft ... the temperature gradient (with respect to pressure) is positively tilted ...
In 100 years, this same dynamic situation will produce -40ºF temperatures due to global warming ... I don't know how this kills billions of people or ruins the global economy ... but if this dynamic can produce -70ºF in February, it's normal as normal can be to produce -44ºF in October ...
So, to correct your tragic mistake ... The
gain in energy input allows a cold low to over power the weaker high pressures ...
ETA: A major Red Flag to indicate Fake News is when temperatures are stated to the nearest tenth of a degree ... just a stone throw away the temperatures could easily be +/- 1ºF ... the extra accuracy is fraudulent ...
