Mercury Barometer Pressure Measurement 1013 mb = 1013 hPa Millibar hectoPascal 1013 mb 29.92 in Hg 76 cm Hg 760 mm Hg 760 Torr 14.7 psi

Station Pressure + Elevation(meter)/10 = Sea Level Pressure

24
Newtons Laws of Motion Newtons 3 laws of motion 1. Law of inertia 2. Net Force = mass x acceleration ( F = M A ) 3. Action Reaction

25
1st Law (Law of Inertia) Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it. acceleration = 0.0 unless the objected is acted on by an unbalanced force

26
1st Law Inertia (The intrinsic tendency of an object to rest changes in motion) Mass is a measure of an objects inertia Mass is also a measure of the amount of an objects matter content. (i.e. protons, neutrons, and electrons)

27
Newtons 2nd Law Net Force = Mass x Acceleration F = M A

28
Newtons Law of Action Reaction (3rd Law) You can not touch without being touched For every action force there is and equal and oppositely directed reaction force

29
Forces that influence the wind 1. Pressure Gradient Force 2. Coriolis Force 4. Friction On average gravity nearly balances the vertical Pressure gradient (hydrostatic balance)

30
Pressure Gradient=P/dist

31
Pressure Gradient

33
Centrifugal force an (Apparent Force)

35
Coriolis Force (apparent force due to Earths rotation)

36
Coriolis Force
