Theory 60/Earth & climate/Fog
Fog Forms on a Cooling Ratio
The claim
Fog forms when the ratio of radiative cooling to moisture supply exceeds a threshold, so a clear calm night with moist air produces fog and a windy one does not.
01Mechanism
Cooling must bring the air to saturation faster than mixing disperses it.
02Prediction
Fog should track the ratio.
03Refutation
Fog tracking humidity alone would remove cooling.
