The Weather Engine
"Weather is the atmosphere revealing its dynamics in real time."
The Dynamic Display
Realm 09 gave us the atmospheric machine: radiation → temperature → pressure → wind. Realm 10 is what happens when that moving atmosphere acquires moisture, instability, boundaries, and disturbances to produce actual weather.
