Review: Pressure-Height

•Remember

•Pressure falls very rapidly with height near sea-level

• 3,000 m 701 mb

• 2,500 m 747 mb

• 2,000 m 795 mb

• 1,500 m 846 mb

• 1,000 m 899 mb

• 500 m 955 mb

• 0 m 1013 mb

• 1 mb per 10 m height

Consequently………. Vertical pressure changes from differences in station elevation dominate horizontal changes
