Measurements have recently been conducted and computer models constructed to determine the coupling of lightning energy into munition storage bunkers as detailed in companion conference papers. In this paper transfer functions from the incident current to the measured parameters are used to construct simple circuit models that explain much of the important observed quantitative and qualitative information and differences in transfer functions are used to identify nonlinearities in the response data. In particular, V{sub oc} -- the open-circuit voltage generated between metal objects in the structure, I{sub sc} -- the short-circuit current generated in a wire connecting metal objects in the structure, and a typical current measurement in the buried counterpoise system behave in a relatively simple manner explainable by one or several circuit elements. The circuit elements inferred from measured data are comparable in magnitude with those developed from simple analytical models for inductance and resistance. These analytical models are more useful in predicting bounding electromagnetic environment values rather than providing exact time domain waveforms. 2 refs.
