Is it the heat effect or the lightning rods effect?

Interesting. The wiki page says that '"Rainfall rates downwind of cities
are increased between 48% and 116%. " I wonder if this is caused by the
urban heat island effect or if it is caused by increased
evapotranspiration from trees and gardens around cities? Wouldn't
warming of the air decrease the likelyhood of precipiation?


Of course. Sahara proves it.

In clouds are excess of electrons. It "brakes" the condensation. In cities
are the lightning rods which conducts the electrons from clouds to ground.
So after some time the condeensation can take place and people downwind of
cities have rain.
In the same way work mountains.
Do you agree?
