Dear Joe and All, I note that you refer to a range of atmospheric pressures between 0700 hPa and 1299 hPa.
Do you know the range of actually observed atmospheric pressure observations that I assume must fall within this range? To put this more directly: What is the highest ever recorded atmospheric pressure? What is the highest ever recorded atmospheric pressure?
