The Influence of Air Temperature on the Dew Point Temperature in Benin City, Nigeria

Research in weather measurement, monitoring and prognostications are becoming more and more pertinent in this era of global warming; getting the appropriate weather predictions and taking the necessary precautions have become very paramount. This research shows the influence of air temperature on the dew point temperature in Benin City, Edo State, Nigeria. The dew point temperature was approximated from the measured air temperature and relative humidity with the aid of a self-designed weather monitoring system in 2016 and the regression equation was obtained using the curve estimation procedure from SPSS 18.0 for Windows and Microsoft Excel version 7. The finding shows that the air temperature and the dew point temperature have a linear relationship and that the air temperature has a significant influence on the dew point temperature; an increase in the air temperature would also result in an increase in the dew point temperature and this would help in the alleviation of climate-induced environmental disasters, improvement in agricultural productivity and also for spatial planning in our communities. It is therefore, recommended that further research work should be done to determine the influence and effect of temperature on other climatic environmental parameters.
