Theory 56/Lake turnover/Progression phase
Mixing Rate Is Depth Against Stability
The claim
The time to fully mix is set by the ratio of depth to the square root of stability, so deep stable lakes mix for weeks.
01Mechanism
Mixing propagates from the surface downward; depth and stability set the rate.
02Prediction
Mixing duration should track the ratio.
03Refutation
Duration tracking wind speed would remove depth.
