winter aerodynamic visualizations
 

Here we have a study of the aerodynamics of my travel trailer. Note the boundary layer separation here:

It appears remarkably uniform, until you look at the lower edges. Here the reversionary flow is apparent by the presence of these vorticles:

The flow starts out normally, then moves forward counter to the direction of travel. This disturbed flow could be improved by judicious use of heat tape.
Here is another example of poor wake turbulence.
Note the severe break into drag-inducing vorticles as pictured here:

Due to the lack of taper, my garage exhibits poor performance across the spectrum. I have yet to achieve orbit with it as a result.

Gotta love nature's design ! here's another interesting manifestation of winter aerodynamics:

Amazing photos guys and thanks for the posts.

We don't see anything like that in my part of the world.
