Air Pressure and Winds I. Review: precipitation types. Sample weather map (Fig. 13.11). Fig. 11.18. Snow. Drizzle. Sleet. Freezing rain. Fog. Atmospheric pressure P. Atmospheric pressure and density decrease with altitude exponentially!!!. Units: 1 bar=1000 mbar.
Atmospheric pressure and density decrease with altitude exponentially!!!
Units: 1 bar=1000 mbar
1 Standard atmosphere: 1013 mbar
by the weight of the atmosphere above
the open air surface.
At higher altitudes, no need for altitude correction: what you measure is what you plot
Typical values for the atmospheric pressure at various altitudes
Sea-level: 1000 mb
3 km: 700 mb
5.6 km: 500 mbConstant height charts
