Abstract

A study of analytic solutions to sets of equations describing surface electric fields in terms of point charge distributions indicates certain conditions concerning the values of electric field in relation to the coordinates of the measurement sites that must be satisfied if real solutions to the simultaneous equations are to be achieved.

A new representation of the surface electric field in terms of cloud monopole and dipole moments is given. Methods of calculating these moments from observed field disturbances and radar measurements of the cloud position and motion are developed. An example of the technique is applied to a winter convective shower situation measured in central Illinois.
