Stability and Cloud Development
So, to assess stability,
what two pieces of information do we need?
20 0 C
30 0 C
14 0 C
8 0 C
Why does the parcel cool
at a slower rate,
6 °C km-1
when it is saturated than
when it is unsaturated?
Unequal heating of surfaces causes parcels to rise.
Cloud Development – Orographic Lifting
LCL – lifting condensation level
Air is forced to rise over mountains.
Whenever air flows together, lifting results
Warmer, less dense air, is forced over cooler, denser air.
