A surface area of 1km x 1km, painted black, will it create convection and induce precipitation?

What would be the side effects of doing such a thing to enhance rainfall?

There are solar farms that are close to that size, so it is possible to test this with real world examples.

Afaik, there has not been any such induced precipitation reported.

I doubt it would do anything.  There are parking lots that have dark pavement that large and it doesn't do anything.

My guess is you’d need something 100 times that size and also some interspersed water features to have a slightly perceptible effect. A hill would probably be more effective. I’ve seen hills not much wider than a km and considerably shorter than a km that effect weather.

Such a weather pattern has been witnessed before, the runway below is exactly 1km^2 , I will attach the images in the next port, some bug here

This is one picture. It means nothing to me. I’d want to see a controlled experiment.

What about the possible effects of pipeline coupling with spaceweather, production of GIC (Geomagnetically Induced Current)?  Even with the thermoelectric generators along natural gas pipelines that are in place to mitigate galvanic corrosion effects of said currents.  Not necessarily affecting precipitation formation but what about CG lightning strikes?
