Wiki: "The urban heat island effect leads to increased
rainfall, both in amounts and intensity,"

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?

Don't forget your increased supply of condensation nuclei courtesy of
your urban areas.

Yes. It is also true. But the main cause is deelectrification of clouds. The
known rule says: "The simplest way is to get inside a home or other sturdy
building during a thunderstorm. Do it immediately; don't wait for the rain
to fall. Most lightning injuries occur before the rain starts and after it
stops. Remember, if you hear thunder, lightning is close enough to strike
you. "

The ligtning rods work like lightnings. They remove electrons from clouds.
After that the rain can fall down.

Actually, that's not true. You can be under a clear blue sky and still
get zapped by lightning from a nearby thunderstorm that you are too
far away to hear the attendant thunder.

Yes. But you confirm that the lightning is always before rain.
So if lightning rods remove electrons from the air the rain can fall down.
Of course downwind of cities.
