Stupid Weather Facts

I recently inherited a really nice German made barometer, hung it up and realized it wasn't working. The mechanism is easily seen and I could tell it was pegged at it's lowest setting (wrapped all the way down passed 28" and back up to 30.5"". Duh, I realized that I had transported this from near sea level so I had to re-adjust it. I did a bit of research and found that a weather barometer is set like an aircraft altimeter, to the corrected barometric pressure. So, there are three pressure readings that have to be taken into account:

1. Station pressure, which is the actual pressure reading at any given place on the globe.

2. Altimeter Setting, which is the corrected pressure shown on nationwide/worldwide weather maps.

3. Mean Sea Level Pressure which is the baseline "average" pressure.

Now for some stupid facts:

Air pressure at sea level is approximately 14.7 psi at a barometric reading of 29.92, here in Denver it's 12.1 psi 24.63 (which corrects to 29.92, no wonder that needle on the barometer was wrapped around). That's 2.6 less psi pushing the air/fuel mixture in when the piston drops... :bootysha: no wonder my junk seems to haul *** when I drive east, lol.

The boiling point of water is directly related to true barometric pressure. Water boils here @ 202 F.

The highest correct pressure ever recorded was in Siberia in 1968 @ 32.01" and temperatures were in the -50 F range. The lowest corrected pressure was in a typhoon over the Western Pacific Ocean @ 25.69".

Just thought I'd post this as the correlation between true barometric pressure and power produced is substantial. 8)
