weather
I love looking at the weather and although I'm not knowlegable in this area I do have my little weather station that hubby brought me for xmas and I;ve been watching it ever since he got it yesterday. I noticed that barometers only gose to certain hight and depth. What would happen if the pressure went any higher than what is on the barometer. I ask because today hubby miss read it and said it was a 2000 and not 1009 as it reads. what would happen if it was that high.
Thanks for your time

If it was that high it could only be because you are somewhere that the amount of atmosphere above you is much higher than normal, I suppose the only way this could happen is if you were at the bottom of a very very deep hole in the earth but I have no idea how far down you would have to be to get 2000mbars.
Mean sea level pressure (MSLP or SLP) is the pressure at sea level or (when measured at a given height on land) the station pressure reduced to sea level by an appropriate altitude dependant formula.
This is the pressure normally given in weather reports on radio, television, and newspapers. When barometers in the home are set to match the local weather reports, they measure pressure reduced to sea level, not the actual local atmospheric pressure.
The reduction to sea level means that the normal range of fluctuations in pressure is the same for everyone. The pressures which are considered high pressure or low pressure do not depend on geographical location. This makes isobars on a weather map meaningful and useful tools.
The highest recorded atmospheric pressure of 1086 mbar occurred at Tosontsengel, Mongolia, 19th December 2001.
The lowest recorded non-tornadic atmospheric pressure of 870 mbar occurred in the Western Pacific during Typhoon Tip on 12th October 1979. The record for the Atlantic ocean was 882 mbar during Hurricane Wilma on 19th October 2005.
