Abstract
Variations in the average daily windspeed, temperature and
atmospheric pressure records in Ikeja and Kaduna were inverstiqated
using time series analytical technique. Results of the harmonic
analysis for windspeed showed that the periodic v a r i a t i o ns
accounted for 40% of the total variance while the f i r s t , second
and third harmonics were found significant. As for the temperature
and atmospheric pressure records, the f i r s t and second
harmonics were found significant accounting for 70% and 90% of
the residual variance respectively. Further stochastic analysis
on the windspeed residuals showed that the purely random
components accounted for 70% of the remaining r e s i d u a l s while
the corresponding values for temperature and atmospheric
pressure were 50% and 20%.
The good agreement between the observed and predicted
values of the elements showed that the predictive models can bo
useful in forecasting pollutant concentrations within an
industrial area if incorporated into the Gaussian Flume model.
