Hiya all!
While reviewing for my interview next week, I realized that I had forgotten the pressure tendency units in the Remarks section of the METAR (US format). As usual is it written down somewhere, but it is hiding from me ... :rolleyes:
It comes in the format 5appp, where 5 represents pressure tendency , (a) the change in pressure, and (ppp) the actual change (tenths of hPa) in the last 3 hours. My question is what exactly the numbers 0-9 in (a) represent.
