WX 201 Exam 2 with correct Answers (Graded A) An unsaturated air parcel cools or warms at what rate? Dry adiabatic lapse rate (DALR) A saturated air parcel cools or warms at which rate? Moist adiabatic rate (MALR) If the environmental lapse rate is greater than the dry adiabatic rate, the atmosphere is: Absolutely unstable Surface cooling and warm air advection aloft generally do what to the atmosphere? Make it more stable An air parcel starts to rise freely when it firs...
