Why does rising steam from a power plant or factory appear to be relatively still from a distance, but when viewed up close it appears chaotic and quick moving? Is there a name for this effect?

From a distance you're only viewing the largest features of the smoke cloud.  Up close, you're viewing much smaller, faster moving features of that cloud.  Due to the fractal nature of such an object these features are different sized but similar looking.  Next time approach the cloud but be mindful to focus only on the largest features of the cloud.
