yes they are

Clearly Tom Evens has no idea what I am talking about with respect to capacitive couplings.  There are two parts.  Charging and discharging.  It takes energy to charge a capaciter, of course, but it need not come from the storm itself.  If a storm is organizing, disorganizing and reorganizing, it may relatively have a lot of lightning.  This has to do with capacitance and how voltages respond.  Think of what would happen if in a capaciter there was a short between plates through the dielectric . . .


In the USAR years ago my MOS or job involved electronics.  In our lab for the USAR there was a football sized capaciter.  It didn't look like much.  It was even painted army green.  But it could store a charge at 50,000 volts.  It didn't crackle one bit.

If there was a short across the dielectric, like a dumb soldier touching the leads of this capaciter in our lab, he would be instantly electricuted and killed. 

The same potential difference in a storm can translate its energy, without lighting, and alter cloud behaviors.  The water uniquely in a storm can act both as a dielectric AND as the altered water in convection processes.  The same kind of storm can't exist over land because land is about 1,000-5,000 times more resistive than the warm tropical oceans and the capacitive relationships don't set up--land won't work like a charge plate.  This is why tropical storms don't exist over land.

All of Tom Evans argument about thermodynamics (yes electrics is a COMPLEXITYon thermodyanmics but one must not forget that convection rates and cloud behaviors are what is behind how clouds trap or release heat and how much shear affects a storm is another question) falls away because there are no studies on cloud microphysics as they pertain to large scale storm behaviors.  He has no contrary proof.  None.  The fact remains that upper level winds blow the tops of these storms with little relative energy and they are done.  Thermodyanmics don't explain track preferences, shear and teleconnections.  By itself, it is limited.
