Let it Rain

Anastassia Makarieva has been graciously keeping me up to date on the goings on with their recent publication. She sent me an email today with a bit of a surprise.
Recently news sneaked in here and there that a “secret” project in Abu Dhabi has successfully created artificial rainstorms.
The reported project leader, Helmut Fluhrer, has an interesting web page http://www.rexresearch.com/fluhrer/fluhrer.htm describing one of their devices. It relies on the condensational
instability of moist air as reported in HESS paper by Makarieva and Gorshkov (2007). Of particular interest is the recognition, see para , that the condensational instability produces updrafts even under atmospheric conditions traditionally regarded as stable. (I remind that according to the condensation-induced dynamics, moist saturated atmosphere is inherently unstable and cannot be static in principle.)
Knowing nothing of this project but just emphasizing (quite unadvertised) interest in our findings from experimentalists, it is interesting to guess.
When using the condensational theory of atmospheric dynamics the UAE become moist and green and recover their forests, will by that time the second referee for our paper in ACPD have been found — or not yet?
