And here was I trying to engineer a way for the moisture to go the
other way down to the great artesian basins


Probably some percent of water migrate down (in the soil) and some up.

I was not aware of this thermal emission of electrons out in the
desert, and what water droplets would be present at such usually low
relative humidities?


It is known that air which is not dry discharge charged bodies. Electrons
and water molecules make an aggregates (we can say droplets). In the Earth
electric field one electron can lift 10^8 water molecules. UV radiation and
high temperature do the work.

If it cools below the dew point (even frost point) overnight, would it
not regain that frost/dew when the land warms up? Or would there be a
time lag, so you would get dried masses of air, that have not had the
opportunity to recapture the dew/frost and then later masses carrying
this evaporated precipitation?
Does the desert act as a dessicant at all?
Perhaps some of the dew/frost (is this called precipitation?) is lost
to lower soil profiles?
Just now, we have an easterly wind that appears to be getting
increasingly humid (specific)


But the content of water is probably lower.


No it's getting higher, (g/kg), I'm not talking relative humidity
here. But at the moment, the air passing my city is unusually moist. I
suspect it is not spending much time away from the sea with the
present patterns.


It is possible if no electrons and when "the air is not spending much time
away from the sea ". But I am not an expert.

and I'm guessing that this actual air
has either not gone over much desert, or has not dropped below the dew
point overnight and is merely a returnimg sea breeze with all of


The wind speed can have something to do also.
