1 ATMOS 5130 Lecture 6 Atmospheric Pressure Pressure Profiles for Idealized Atmosphere

2 Goal Understand how temperature, pressure and altitude are related in the atmosphere. Recall from last lecture Hypsometric Equation Δz = R &T ( g ln p - p. Allow for calculation of pressure at any height

3 Pressure Profiles for Idealized Atmosphere Constant Density Atmosphere Unrealistic Better representation of the ocean Atmosphere had the same mass as now, but had a constant density it would be only 8.3 km deep :1 :8 ρg Hydrostatic Equation 1 (3) 8 / dp = ρg / dz p z = p 9 ρgz Pressure decreases linearly with height

4 Pressure Profiles for Idealized Atmosphere Constant Density Atmosphere p z = p 9 ρgz Pressure is decreasing with height Density is constant SO, Temperature must decease with height p = ρr & T IDEAL GAS LAW p z = ρr & T z Substitute in Hydrostatic Equation Differentiate with respect to elevation p z = ρg := :8 = = C/km

5 Constant Density Atmosphere Autoconvective Lapse Rate p z = p 9 ρgz := :8 = = C/km = Γ BCDE When: Γ > Γ BCDE Density above greater than below! Density Inversion => Creates a mirage Above a very hot road, a layer of warm air whose density is lower than air above. The denser air slows light very slightly more than the less dense layer. So, one sees sky where the road should be, we often interpret this as a reflection caused by water on the road

6 Pressure Profiles for Idealized Atmosphere Constant Density

7 Pressure Profiles for Idealized Atmosphere Isothermal Atmosphere &1 &8 = ρg Hydrostatic Equation Again substitute in the ideal gas law, Solve dp dz = ρg = pg R & T 1 g dp = p R & T dz 1 / 1 dp = g p R & T / dz 9 ln p p 9 = gz R & T p z = p 9 exp z H Where: H = R &T 9 g

8 Scale Height p z = p 9 ρgz Scale Height (H): solve for z, when p(z) = 0, H = p 9 ρg substitute the Ideal Gas Law Constant Density Atmosphere Approximate scale heights for selected Solar System bodies Venus: 15.9 km Earth: 8.3 km Mars: 11.1 km Jupiter: 27 km Saturn: 59.5 km Titan: 40 km Uranus: 27.7 km Neptune: km Pluto: ~60 km H = R &T 9 g In other words: scale height is the increase in altitude for which the atmospheric pressure decreases by a factor of e -1 or about 37% of its original value.

9 Pressure Profiles for Idealized Atmosphere Constant Lapse Rate atmosphere T = T 9 Γz Normally Γ >0, temperature decreases with altitude When Γ >0, temperature increases with altitude INVERSION

10 Pressure Profiles for Idealized Atmosphere Constant Lapse Rate atmosphere T = T 9 Γz Take the hydrostatic equation and combine with Ideal Gas Law dp dz = ρg = pg R & (T 9 Γz) 1 p dp = g R & dz T 9 Γz 1 / 1 dp = g 8 dz / 1 5 p R & 9 T 9 Γz ln p p 9 = g R & Γ ln T 9 Γz T 9 p(z) = p 9 T 9 Γz T 9 Q

11 Pressure Profiles for Idealized Atmosphere Constant Lapse Rate atmosphere T = T 9 Γz Take the hydrostatic equation and combine with Ideal Gas Law dp dz = ρg = pg R & (T 9 Γz) 1 p dp = g R & dz T 9 Γz 1 / 1 dp = g 8 dz / 1 5 p R & 9 T 9 Γz ln p p 9 = g R & Γ ln T 9 Γz T 9 T(z) p(z) = p 9 T 9 Γz T 9 Q

12 Pressure Profiles for Idealized Atmosphere Constant Lapse rate atmosphere p(z) = p 9 T(z) T 9 Q Valid for Γ < 0 Exponent of the ratio is negative, so pressure still decreases with height Q is ratio of autoconvective to actual lapse rate So, what happens if Γ = Γ auto?

13 Pressure Profiles for Idealized Atmosphere Constant Lapse rate atmosphere p(z) = p 9 T(z) T 9 Q Valid for Γ < 0 Exponent of the ratio is negative, so pressure still decreases with height Q is ratio of autoconvective to actual lapse rate So, what happens if Γ = Γ auto? p(z) = p 9 =(8) = 5 - Pressure is linear function of z
