after watching the animation, you should recognize that the environmental lapse rate (elr) varies, which influences the state of the atmosphere. for this weekly lab exercise, we will assume that the environmental lapse rate is 12 degrees c/ 1000 m. now that we have raised the air parcel to the lifting condensation level (lcl) - 2000 meters, how much has the environment cooled? is the air parcel stable or unstable?
