             abstract = "Cloud electrification models are a powerful tool to study the 
                         physical mechanisms that are responsible for the existence of 
                         electric field inside thunderstorms. These models are very complex 
                         and include a wide variety of cloud properties, atmospheric 
                         motions and physical interactions. In this work, we present the 
                         equations to simulate the dynamics and convection of a cloud in 
                         3D. By solving the three equations of conservation of momentum, 
                         the thermodynamic and the continuity equations we can simulate 
                         various physical processes necessary to create a thunderstorm 
                         cloud. The equations for conservation of momentum include the 
                         contribution from the pressure, wind advection and friction and 
                         the thermodynamic equation will consider turbulent effects as well 
                         as latent heat absorbed or released from the hydrometeors phase 
                         transitions. Coriolis effects will be neglected. The next stage of 
                         the study will be the inclusion of the microphysical equations, 
                         considering seven classes of hydrometeors, charge transfer 
                         equations to be associated with the microphysical interactions and 
                         a parametrization of the initiation of a lightning discharge. The 
                         electrification model will be fully coupled with the dynamical and 
                         microphysical equations. Sensitivity tests will be performed to 
                         verify which electrification mechanism leads to the most realistic 
                         results by comparing the output of the model with data acquired 
                         from a real thunderstorm.",
