EATS 1011 3.0 Introduction to Atmospheric Science 1 of 6 YORK UNIVERSITY FACULTY OF SCIENCE Department of Earth and Space Science and Engineering EATS1011 3.0 Introduction to Atmospheric Science Multiple Choice test 20 minutes from 11:05-11:25 AM Vari Hall A 21 st April, 2009 Useful quantities that you may need. Permitted Aids: A calculator and a standard dictionary. Answer the questions on the SCANTRON answer sheet provided using a soft pencil. Black or blue ball point pen will not be read properly. Be sure that your name and student number appears on the SCANTRON answer sheet. Red indicates what could have been used (but not always really necessary) for calculations. 1 AU = 1.50x10 8 km. Speed of light = 3.0x10 8 m/s. Density of air at MSL, ρ air = 1.2 kg m -3 . The Coriolis parameter, f = 2 Ω sin(latitude) The Coriolis parameter, f = 1.0 -4 s -1 at 43.5 ° latitude. Molecular weight of O 2 = 32 Gravity on Mars = 3.7 m s -2 p = ρ RT Universal gas constant R* = 8.3143x10 3 Jdeg -1 kmol -1 The Gas Constant for a molecule of mass, m, R = R*/m Density of liquid H 2 O: ρ H2O = 10 3 kg/m 3 Dry adiabatic lapse rate, Γ D = g/C P = 10°C /km. Latent heat of Fusion for water ice = 335,000 J/kg Saturated adiabatic lapse rate, Γ M = 6°C /km (nominal). Solar Constant, E = 1.38 kJ m -2 s -1 . Stefan-Boltzman constant, σ = 5.67x10 -8 J m -2 s -1 K -4. The Effective temperature, T eff = ((1 - A) E /(4 σ r p 2 )) 1/4 Mean radius of Earth = 6370 km Degrees Kelvin = degrees C + 273 1 year = 3.16x10 7 s. 1 mb = 100 Pascals Wien's Law λ max T = 2.9x10 3 μ m °K Stephan Boltzman Law Flux = σ T 4 J m -2 s -1 The scale height, H = RT/g metres Mean acceleration due to gravity on the Earth: g = 9.8 m s -2 The Hydrostatic Law: p(z) = p(0).exp(-z/H) where H is the scale height Mass of atmosphere/m 2 = surface pressure (Pa)/gravity kg/m 2
