What usually happens when a parcel of air cools more slowly the air in motion, leads to the formation of clouds as moisture accumulation takes place. Thus the vertical ascent of air reduces its capacity to store or hold water and hence condensation occurs at dew point.
The rising parcel of air cools and descents down the original dew point and results in net condensation. Thus the lifted parcel of air reaches o its 100% concerning Adiabatic cooling.
