Theory 03/Monsoons/Ratio lens
Strength Is an Evaporation Split
The claim
Monsoon strength is set by the ratio of oceanic to terrestrial evaporation rather than by total evaporation.
01Mechanism
Ocean moisture arrives advected while land moisture is local; the mix determines where convection forms and how deep the circulation reaches.
02Prediction
Strength should track the ratio across basins.
03Refutation
Strength tracking total evaporation would remove the partition.
