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. Density of air at MSL, ρ air = 1.2 kg m -3 . The Coriolis parameter, f = 2 Ω sin(latitude) The Coriolis parameter, f = 1.0x10 -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 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 . Degrees Kelvin = degrees C + 273 1 year = 3.16x10 7 s. 1 mb = 100 Pascals 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 The geostrophic wind, ρ ΔΔ == 1 g Pg Z V fn fn m s -1 1 of 8
