Environment
The atmosphere outside the air parcel
Unstable environment
When the air parcel is warmer than the environment and keeps rising
Stable environment
The air parcel is cooler than its environment and sink back to its original position
Conditionally unstable

What is Lifting Condensation Level
Seen as the cloud base
Lifting condensation level
If the air is lifted to the cloud base
Level of free convection
The level where the parcel becomes buoyant
Lifting mechanisms
Whatever lifts air parcels
