A Taylor column is a feature of the coriolis effect. It was named after Geoffrey Ingram Taylor. Rotating fluids that are perturbed tend to form columns parallel to the axis of rotation called Taylor columns.
In a rotating fluid a strongly buoyant ball (such as a pingpong ball) will rise to the surface slower than it would in a non rotating fluid. Fluid that is shifted from its position in the rotating system tends to be pushed back to the point it is shifted away from, the faster the rotation rate, the smaller the radius of the inertial circle.
In a non-rotating fluid the fluid parts above the rising ball and closes in underneath it, offering relatively little resistance to the ball. In a rotating fluid, if certain conditions are met, the ball needs to push up a whole column of fluid above it, and it needs to drag a whole column of fluid along beneath it in order to rise to the surface.
A rotating fluid has a specific kind of rigidity, it does not quite act like a fluid anymore.
Taylor columns were first observed by William Thomson, Lord Kelvin, in 1868. Taylor columns were featured in lecture demonstrations by Kelvin in 1881 and by John Perry in 1890. The phenomenon is explained via the Taylor-Proudman theorem, and it has been investigated by Taylor, Grace, Stewartson, and Maxworthy — among others.
