These last few days have been medically challenging due to a sudden onset of pulmonary oedema and some urgent medical attention. I mentioned this to a good friend in Western Australia who also mentioned that for the first time since his teen-age times he suffered a minor attack of asthma. This puzzled me. It became less puzzling when an inquisitive relative mentioned, en passant, the present tropical cyclone near Fiji in the Pacific Ocean; this rang my electric plasma bell.
Cyclones are strong negative pressure atmospheric vortices dominated by excess negative electric charge. This has to be balanced elsewhere by high pressure cells with excess positive charges. The following BOM graphic is for 20th February 2016.
Clearly the southern portion of Australia is dominated by high pressure atmospheric cells. I live in the SE corner of Australia. My friend lives in Perth. Pressure differential between Perth (1009 hPa) and my location (1020 hPa) is some +11hPa; hence atmospheric pressure is higher where I am by some 11 hPa.
Breathing is basically fighting atmospheric pressure to expand one’s lungs, and the higher the pressure, the harder it is to inhale. Which might explain why my friend had a mild asthmatic incident and I a somewhat more intense one, everything else being equal. I also have a heart operating at 50% capacity, with AF, so I might be more sensitive to perturbations in atmospheric pressure.
It’s more complex than what I have briefly described here but when the hospital is at a loss to explain my breathing difficulties, it’s always interesting to check the physical environment. This means checking my breathing performance and plotting it against atmospheric pressure on a daily basis.
