Summary The two-dimensional differential equation which governs the electrical potential of an atmosphere whose conductivity is given by $$\lambda = \lambda _0 \operatorname{e} ^{\beta z} $$ is solved numerically for a region above a simulated mountain range or a semi-infinite plateau wherez is the altitude. The effect of pollution below an inversion can be included by using different values ofλ 0 and β below and above the inversion. As would be expected, theresults show that in a simple exponential atmosphere the potential increases more rapidly above the peak than avove the plain far from the mountain range. However, if a polluted inversion layer is present below the peak then the increase in the electric potential may be greater immediately above the plain than above the mountain peak which protrudes above the pollution layer. From these solutions values of the vertical and horizontal electric fields and the enhanced current density at the peak can be caculated.
