Chapter 03 of 5
The Wall of Water
The physics of orographic lift and mountain-induced deluges.
- The Impact
A Sky-High Collision
When a fast-moving atmospheric river slams into a coastal mountain range, the water doesn't just pass over. It undergoes a violent physical transformation.
- Mechanism
Orographic Lift
As the moist air hits the slope, it is forced upward. This mechanical lifting is the primary trigger for extreme precipitation events.
- Thermodynamics
Adiabatic Cooling
As air rises into lower pressure, it expands and cools. Cold air cannot hold as much moisture as warm air, leading to rapid condensation.
