Oh, not. That's just fucking asinine. Wind at the surface always moves along the surface. Dirt doesn't just absorb downdrafts. The air has to go somewhere, where it goes is parallel to the surface. Our vantage point is at like 4 feet of altitude. A downdraft could exist here, but it would be less than 4 feet diameter, like a ceiling fan blowing down or something. This is a huge tornado and even if there were such a thing as an eye it would be larger than 4 feet. Also, a 4 ft center passing over would be barely perceptible in time. So if there is such a thing as a downdraft center it is certainly too large to perceive from 4 ft. But actually no such center exists. Hurricanes have such a descending center, but the eyewall of a hurricane is a thunderstorm driven by condensation releasing latent heat. It would rise, and the surrounding air sink, even with no rotation. A tornado is just a vortex driven by low pressure. There is condensation, and it is releasing heat, but the center of a tornado also has condensation. There's no reason for a descending center. I mean, it's possible, but then you'd have an eye visible from space since descending air absorbs water vapor as it warms adiabatically. We don't see tornado eyes from space, therefore there is no descending center.
