Resumen:
In this work we present the results of experimental measurements of the charge transferredto simulated graupel under wet growth conditions. The range of temperature was between -7oC and -18oC. The speeds of collision employed in the measurements were between 8 and13m s-1 with the goal of representing graupel of different initial densities. The aim of thisstudy was to corroborate the existence of charge transfer under wet growth. The resultsshow the presence of positive charge when graupel reaches partial wet growth, and themagnitude of this charge is comparable to the charge transferred under dry growthconditions. On the other hand, when total wet growth is reached no charge transfer isregistered. This leads to the conclusion that the non-inductive mechanism could be workingunder partial wet growth conditions when the ice crystals collide with the dry regions of thegraupel surface and then bounce off.
