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 (http://en.wikipedia.org/wiki/Planetary_boundary_layer), low
700 hPa |
~3,500 m, planetary boundary, high
500 hPa |
~5,000 m, vorticity (http://en.wikipedia.org/wiki/Vorticity)
250 hPa |
~10,500 m, jet stream (http://en.wikipedia.org/wiki/Jet_stream)
70 hPa |
~17,500 m, stratosphere (http://en.wikipedia.org/wiki/Stratosphere)
10 hPa |
~26,500 m, even more stratosphere
the "Surface" layer represents conditions at ground or water level
this layer follows the contours of mountains, valleys, etc.
overlays show another dimension of data using color
some overlays are valid at a specific height
while others are valid for the entire thickness of the atmosphere
Wind |
wind speed at specified height
Temp |
temperature at specified height
TPW (Total Precipitable Water (http://en.wikipedia.org/wiki/Precipitable_water)) |
total amount of water in a column of air
stretching from ground to space
TCW (Total Cloud Water) |
total amount of water in clouds
in a column of air from ground to space
MSLP (Mean Sea Level Pressure (http://en.wikipedia.org/wiki/Atmospheric_pressure#Mean_sea_level_pressure)) |
air pressure reduced to sea level
MI (Misery Index) |
perceived air temperature
combined heat index (http://en.wikipedia.org/wiki/Heat_index) and wind chill (http://en.wikipedia.org/wiki/Wind_chill)
