Unformatted text preview: NAME: EXAM II, ATMO 335, March 24, 2008. OPEN BOOK 1. A 1kg parcel of dry air is initially at a temperature of 283K and pressure 1000hPa. It is transformed (quasi-statically and reversibly) in two steps. i) It is lifted adiabatically to a pressure of 800hPa. ii) It is then heated at constant pressure by 10kJ. a) What is T at the end of steps (i) and (ii)? T = 283K; T 1 = T p p . 286 = 265 . 5K; T 2 = Q/c p + T 1 = 275 . 5K b) What is S at the end of steps (i) and (ii)? 1 S = 0; 2 S = R T 1 T dQ T = R T 1 T c p dT T = c p ln T 1 T = 36 . 975JK- 1 c) What is the potential temperature initially? = 283K since = T ( 1000 1000 ) d) What is the potential temperature at the ends of steps (i) and (ii)? i) 1 = ; ii) 2 = T 2 (10 / 8) . 286 = 293 . 6K; 2. A parcel of air at 283K and 1000hPa has relative humidity r=0.50. a) What are the saturation vapor pressure and the saturation mixing ratio?...
