Hope to expand on this later. A community for discussing the weather (very UK), amateur meteorology, and moaning it's too hot/cold/wet/dry/mild.

How come there are currently large low pressure zones at North Pole and South Pole? (mander.xyz)

Looking at https://zoom.earth/maps/pressure/

Given the much lower temperatures at the poles, I would expect the pressure to be (much) higher.

I'm reading here and there that air pressure at the antarctic is low because of its high altitude, but these maps show (I presume?) MSLP?

Also, the formula Pressure = density x R x T doesn't show that pressure decreases as temperature decreases, since a temperature decrease also increase the density?
