EATS 1011 3.0 Introduction to atmospheric science 1/4/2008 1 of 6 YORK UNIVERSITY FACULTY OF SCIENCE Department of Earth and Space Science and Engineering EATS1011 3.0 Introduction to Atmospheric Science Mid-Term Atmospheric Test I have marked in red bits that were used for the test There are two sections. Attempt all the questions in section A which are worth approximately 80%. Attempt two (b) questions only in Section B worth ~20%. Permitted Aids: A calculator and a standard dictionary. Answer the questions in Part A on the SCANTRON answer sheet provided using a soft pencil. Black or blue ball point pen will not be read properly. Write your answers to Part B on the Examination Book. Be sure that your name and student number appears on the SCANTRON answer sheet, and on first page of the Examination Book. Universal gas constant R* = 8.3143x10 3 Jdeg -1 kmol -1 R = R*/m Specific heat at constant pressure for air, c p = 1,007 J/K/kg Surface area of a sphere of radius r = 4 π r 2 . Circumference of circle of radius r = 2 π r. Volume, V, of a sphere of radius r: V = 4/3 π r 3 1 AU = 1.50x10 8 km. Speed of light = 3.0.10 8 m/s . Density of air, 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 CO 2 = 44 Gravity on Mars = 3.7 m s -2 p = ρ RT Density, ρ H2O , of liquid H 2 O: ρ H2O , = 10 3 kg/m 3 Dry adiabatic lapse rate, Γ D = g/c P = 10°C /km. Saturated adiabatic lapse rate, Γ M = 6°C /km (nominal). Solar Constant, E = 1.38 kJ m -2 s -1 . Stefan-Boltzman constant, σ = 5.67 -8 J m -2 s -1 K -4. The Effective temperature, T eff = ((1 - A) E /(4 σ r p 2 )) 1/4
