The net evaporation field (evaporation minus precipitation) shows that atmospheric water vapor is transported from the night side to the day side.
Again, though the water vapor emitted from cooling towers can and does create impressive cloud formations under the right conditions, this is a very different issue than being the primary mechanisms of Earth's atmospheric water vapor generation for fueling storms which is what some are falsely claiming.
At this point since there are papers out there that suggest a negative feedback and the 2.5 + x positive water vapor feedback from the IPCC is clearly a non-starter in view of the pause, CAGW has to demonstrate via real atmospheric studies what the actual feedback is.
The Special Sensor Microwave Imager (SSM / I) radiometers provide brightness temperatures at three different frequencies (19.35, 37.0 and 85.5 GHz) from which are estimated: wind speed when not raining, integrated atmospheric water vapor content, liquid water content, and a rain index.
