'millibar'. 1 millibar = 1 / 1000 bar and 1 bar = 1 atm.
I was noticing that something had changed: the 500 millibar heights seemed to be getting higher.
At the same time, what meteorologists call the "1000-500 millibar thicknesses" had demonstrated a similar trend.
Catastrophic burning events are related to the breakdown of the 500 millibar (mb) long-wave ridge .
That 906 millibar pressure reading was at landfall, making Dean the third most intense landfalling hurricane known in the Atlantic region and the first Category 5 storm at landfall since 1992's Hurricane Andrew.
On weather maps, pressure is indicated by drawing isolines of pressure, called isobars, at regular 4 millibar intervals (e.g., 996 mb, 1000 mb, 1004 mb, etc.).
They've just found the pressure at the surface has dropped by a millibar, so that's an indication that we're starting to see some strengthening.
This one came out of Kessler Airport Base, doing its alpha pattern and it measured 946 millibar low.
That's about what it was last night, maybe a millibar off.
I am assuming that the 906 millibar reading comes with an error so rank ordering should come with a CI.
