Abstract
The study of the weather and weather parameters of a region is very significant for sustainable development of agriculture, urban planning and economic growth. Therefore, this research is focused on the investigation of the observable variations and trends in some meteorological parameters (Rainfall and Temperature) in Port Harcourt Metropolis for a period of 11 years (2008-2018). The results from the statistical analysis depict the highest Correlation of Variation (CV) for rainfall in January (219.67%), and the lowest CV for rainfall was recorded in June (7.32%). Conversely, the maximum temperature has its maximum CV in May (14.77%) and its lowest CV in July (1.1%). This finding depicts that temperature is a more stable parameter than rainfall. The monthly mean of rainfall for the 11 years has its peak in June and its lowest in December. Furthermore, the result reveals a strong anti-correlation in CV between maximum temperature and rainfall. There were also indications of a strong correlation between temperature and rainfall over the years studied. A similar trend was observed in the cross plot of annual rainfall against maximum temperature. Finally, the ANOVA analysis reveals that F-cal is 0.14, which is slightly higher than F.tab at α = 0.05, which implies a significant difference in rainfall amounts between the months, indicating a non-random pattern in rainfall. However, no significant difference was observed in temperature trends over the period. The result from this study is relevant for effective monitoring of weather conditions in Port Harcourt city and can be useful for future prediction and timely responses to extreme events.
