Problem 1 Role of entrainment on a rising air parcel The fractional change (1076' in the potential temperature 9' of a parcel of cloudy air produced by a fractional change of mass m of the parcel due to the entrainment of mass dm of unsaturated ambient air is d6\" L1, T' T L1, dm F dais + (11.1.; w) cpT' T' cpT' ' m where T' is the temperature of the cloudy air parcel and T is the ambient air temperature. 1. What. does this expression reduce to for the dry adiabatic case, that is the case of no condensation and no entrainment? 2. What does this expressiou reduce to for the case of condensation but no entrainment? 3. Show that the potential temperature of a rising parcel of cloudy air decreases faster when entrainment is present than when entrainment is absent
