It has been proposed that Venus' atmosphere at the altitude of around 50 km could be colonized with large aerostats. Since Venus' atmosphere is largely CO2 regular air acts like a lifting gas. So it has been proposed that a small city could be lofted by a balloon filled with air of similar size to a small city(~km in diameter).
My question is could Venus' atmospheric turbulence and wind shear at these altitudes make constructing such large aerostats infeasible due to structural reasons? Turbulence and wind shear seem to have played a part in a number of airship disasters here on earth. Would said turbulence or other atmospheric processes on venus be sufficient to irreparably damage or fatigue at an impractically high rate aerostats made from the typical materials we make balloons from on earth? Or is the rate at which an individual aerostat encounters fatally damaging turbulence similar to the rate at which an individual city on earth experiences a large natural disaster?
To preempt the trivial answer of just avoid the turbulence and because it is my opinion that propelling a large balloon the size of a city is impractical, let's only consider non-propulsive aerostats. Although I will concede that buoyancy control is allowed. A large aerostat may be considered to be one that has a payload of =>750,000 tons or a diameter => 1 km.
EDIT: Because a non-propulsive aerostat is to be considered, it can be assumed to move freely with the wind and does not station keep.
