The biotic pump theory came out about 2006. Enhanced precipitation over rainforests created low pressure zones and these created a wind from the ocean to the land and this brought in even more moisture.
The biggest objection was that enhanced precipitation was precieved to cause high pressure (not low pressure as the nuclear physicists suggested). And high pressure does not suck anything. And now it is about 9 years later and they are still arguing about this. My contribution is that I did a cloud in the bottle experiment and if you have high pressure the cloud itself disappears.
So how can high pressure be associated with clouds at all? And indeed, low pressure areas are normally full of clouds while high pressure is the clear blue sky type deal. A while back a team discovered that in the rainforest, fungi release potassium salts when they release spores, and the salts are a seed that isoprenes from trees condense on and this combination is a great condensation nuclei for rain.
So there is enhanced rainfall. But can we prove or disprove the low pressure? The Russian physicists have a page at http://www.bioticregulation.ru/pump/pump.php and I have a playlist at https://www.youtube.com/playlist?list=PLkzXlmAwZTZeMM52PvvkX0JN1pwDCQ8q0 with people talking about the theory.
My take is that cloud are an area of 2 phase fluid flow, warming drying air flowing up through a falling layer of droplets. So clouds are heating and drying the upward moving air, while cooling the falling water. Even if rain never happens, this is going on. The cloud itself is pumping air up into the sky.
Without the conversion from water vapor to droplets, this does not happen. (I think). Instead the air will simply expand as it heats in the day and contract as it cools at night. All heat loss will be by radiation.
But in the cloudy skies, convection through the cloud is the main mover of energy and this convection through the cloud creates air movement not heat. Anyway, any ideas on how to prove if clouds are creating high pressure or low pressure?
HVAC engineers might know more about this than meteorologists and might be able to cut through the BS and suggest an experiment to prove or disprove it? Most of the battle about this is waged with equations and really, I think this is too turbulent for them to be reliable.
