atmospheric pressure corresponds roughly to altitude

several pressure layers are meteorologically interesting

they show data assuming the earth is completely smooth

note: 1 hectopascal (hPa) = 1 millibar (mb)

1000 hPa ~100 m, near sea level conditions
850 hPa ~1,500 m, planetary boundary, low
700 hPa ~3,500 m, planetary boundary, high
500 hPa ~5,000 m, vorticity
250 hPa ~10,500 m, jet stream
70 hPa ~17,500 m, stratosphere
10 hPa ~26,500 m, even more stratosphere
