Relationship between relative humidity and the dew point temperature in Benin City, Nigeria
The influence of weather in all aspects of human endeavours is evident in the recorded loss of lives and properties due to weather related disasters usually triggered by global climate changes. Hence, the need for the collation of information about the temporal dynamics of weather changes is of paramount interest. This research was aimed at determining the relationship between relative humidity and 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 currently self-designed weather monitoring system. The results showed that the relationship between the relative humidity and the dew point temperature were linear with significant coefficient of determination (R2) of 0.79. The relative humidity and the dew point temperature are prospective tools in weather prognostications and are used to express the amount of moisture in the air, this would help guide against the occurrences of climatic induced environmental disasters in our communities.
