What are the good reasons to have constant rain on the city?
I'm working on a cyberpunk world, and thought to have the usual trope of having constant downpour. But I thought, what about having a very big disk-like structure that hover over ~30% of the world. Outside of which is just barren land. The disk works as a shield against the sun radiation and the structure hanging beneath as a residence for the wealthy people. From that disk, they drizzles almost every few hours. But the water is purified wastewater of the wealthiest. But I'm reconsidering, so does having a normal sky with constant clouds and rain works? What would be best?
