On the modeling of electrical boundary layer (electrode layer) and derivation of atmospheric electrical profiles, eddy diffusion coefficient and scales of electrode layer

Abstract

Electrode layer or electrical boundary layer is one of the charge generators in the global atmospheric electric circuit. In spite of this we find very few model studies and few measurements of it in the literature. Using a new technique it is shown that in this layer, the space charge density varies exponentially in vertical. A new experimental method based on the surface measurements is discussed to determine all the characteristic scales and an average electrical and meteorological state of an electrode layer. The results obtained are in good agreement with the previous studies. So, it is suggested that an exponential space charge density profile will no longer be an assumption in the case of electrode layer studies. The profiles of atmospheric electric field and electrical conductivity are also derived and a new term named as electrode layer constant is introduced.

“…This conductivity is the steady state conductivity ( λ ( ∞ )) attained at the top of electrode layer (a layer of space charge near the electrode i.e. in the present case space charge layer near the earth's surface) 20 21 22 23 which is in between the earth's surface and the top of BL. In highly turbulent conditions the top of electrode layer may reach the top of BL 24 .…”
