Breakdown voltages that are lower than the regular 30 kV/cm may
appear as a consequence of high temperatures in the gap terminals
or in the surrounding air, not counting changes in composition and 
partial ionization of the air, or irregularities in the terminal
surfaces. If temperatures of 600 K are reached the
figure should fall to about 15 kV/cm just due to the temperature.
