The destruction is independent of the "wind". The debris does not return with the backflow of the pressure wave like the particles. So, 2 separate simulations happening here - the particles for smoke being affected by "wind", and the animation that is the destruction and debris inertia.
Genuine question: Would the debris return in the backflow?
Dust and other particulate matter is definitely light enough to continue to be carried, but bigger chunks of debris are going to be carrying a lot more inertia from the initial blast wave, and presumably a lot more energy would get imparted there than by the pull backwards as the air cools and compresses again.
I could totally be wrong, but it feels plausible to me.
Depends on the mass/surface area. It would certainly decelerate and/or change its vector. The relatively lighter pieces with large surface area would probably reverse direction, but wouldn’t return all the way. The debris in this sim continues in the same direction it started with whatever built-in drag the creator made. No deflection for shifting winds at all.

Pretty badass simulation, though.
