I think we can predict with great accuracy what's the weather going to be in a small O'Neill cylinder since we get to control the humidity and air flows, etc but then a tiny variation in temperature could spell trouble brewing at one corner of the space habitat.
I suspect minute variations in temperature on the ground surface could easily spawn a vortex of hot air which can grow exponentially in size in no time, but I think the ingenious hardscape layout might help prevents it from happening in the first place.
Is there a way to control weather in a large enclosure? Could this set a limit for the size of each O'Neil Cylinder?
For hardscape I meant we have trees plantation to absorb most of the energy of winds and perhaps we could have tall infrastructures with pyramid roof design to dissipate the energy of wind thus preventing buildup of small vortexes.
