Theory 52/Earth & climate/Precipitation efficiency
Rainfall Efficiency Is Condensed Against Lost
The claim
Precipitation efficiency is set by the ratio of condensation to re-evaporation, so a dry sub-cloud layer can evaporate most of what falls.
01Mechanism
Drops must survive the descent; the ratio determines surface rainfall.
02Prediction
Efficiency should track the ratio.
03Refutation
Efficiency tracking cloud depth would remove re-evaporation.
