This paper presents the modeling of the static electric field in Zaria, Nigeria during the harmattan
season, based on the on-line data capturing mechanism, which involved the use of a data acquisition system,
interfaced with a digital electrostatic field strength meter (model 257D), and a computer system. The acquired
electric field data are captured by the computer using the Microsoft Office Excel Program and data captured
for twenty-four months (February, 2007-February, 2009). The focus of the analysis is determining the effect
of environmental factors such as temperature, pressure and relative humidity on the static electric field during
the harmattan season. The plots of the electric field against the variation of the environmental factors were used
as the qualitative analytical tools. The data were statistically analyzed using a non-linear regression model to
obtain an equation model for the harmattan period as E =-269.65430 - 0.022853*H + 0.0004187*T +
0.3805523*P. The standard error between the model and experimental value was 0.009. This was found to be
insignificant; hence, the mathematical model established could be relied upon to predict electrostatic fields
during harmattan in the Northern part of N igeria.
