I would expect that's because they really need a HV DC source with some 
capacity behind it to simulate a cloud -- something more like a Van De Graaf
rather than a pulsed TC.

The HV on a TC is only present for a small fraction of the running time, 
and the top capacitance on a TC is nowhere near large enough to hold the
energy needed to generate a single long arc event.  A typical lightning
strike will often have tens of coulombs behind it.
