Abstract

Objectives: Urban thermal comfort is higher than the rural due to massive anthropogenic activities. Hence a statistical and simulation analysis is required to estimate minute changes over the thirty decade. The uncontrolled injection of aerosols from industrial waste emission, decay of matter, biomass burning has its collective effect on the thermal comfort of the urban climate. Methods: The research site i.e. Ilorin, Nigeria is located in the middle of the Guinean zone coastline and Sudano-Sahelian zone. Thirty years (1981-2012) ground data from the Nigerian Meteorological Center was obtained for the study. Thermal comfort was statistically analyzed-using three key parameters i.e. surface temperature, relative humidity and hours of sunshine. Results: Two crucial factors were seen to affect the thermal comfort of the study site i.e. regional climate and aerosol emission volume. Four months i.e. November, December, January and February may be detrimental to people having respiratory or circulatory health challenges. This is because of the connection between thermoregulatory mechanisms and the circulatory/respiratory system. Conclusion: Thermal comfort has increased over thirty years. Hence, the health status of life forms is threatened. The geometrical transition of the thermal comfort between November to February shows that people with respiratory health challenges have low survival during the months of November, December, January, February and possibly March.
