Forcing air currents in urban areas for weather change. Ideas #1

I’m not a meteorologist or an expert in the matter. Anyway it doesn’t mean I cannot have an idea. Maybe it makes sense or it doesn’t, anyway here it is.

Summer in Tokyo is like hell on earth. Huge humidity and this year will be remembered in particular. I always read that the main causes are urbanization disorder that prevents air from moving, extensive use of air conditioning and inefficient construction materials that absorb heat. I don’t know if these are the causes. Anyway what if we paint the roofs in one area white and another dark. That will create a difference in temperature and therefore an air current. There are articles that predict that white roofs are not the solution and that it will be even worse. (here, here)

But what I’m saying here is not about just reflecting light. I’m thinking about how to create a huge cheap ventilator effect inside the city.


Air in the dark area heats up, and creates a current moving from the white area. The idea behind this post is to use huge areas to work as artificial ventilators creating air currents by using houses roofs for heat absorption or heat reflection.
