..according to this story which reports a professor telling a conference that tall and large buildings can induce rainfall/bad weatherl! This professor thinks that cities are now creating their own weather systems.

I don't know about the rain thing.
But it has been known for years that cities are generally warmer then outlying areas. This is a mostly because the dark pavement and roofs soaking up heat from the sun much more effectively then fields and trees.
But heat loss through the walls of heated buildings also contributes.
It has also been shown that air pollution particles can act as "seeds" in the formation of fog.
