isobars on a skew-T diagram

The horizontal lines are isobars, spaced logarithmically from 1050 up to 100 hPa. They are plotted every 50 hPa.

On paper versions of the skew-T/log-P diagram, the ICAO standard atmosphere heights are printed under selected isobars on the right hand side of the diagram in feet (in parentheses) and meters [in brackets]. There is also a height scale to the right of the diagram.
