Abstract :
This investigation focused on solar forcing on climatic parameters in Nigeria and their effects. The daily meteorological data for five climatic parameters; Minimum Temperature (MIT), Maximum Temperature (MAT), Relative Humidity (RH), Vapour Pressure (VP), and Rainfall (RNF) obtained from Nigeria Meteorological Agency (NIMET) and two solar parameters Total Solar Irradiance (TSI) and F10.7 cm solar radio flux (F10) from sorceTM were graphically represented and were modeled using a proposed linear multivariate model and the empirical coefficient determined by applying least square fittings. The validity of the model was tested using the statistical indicator; Mean Bias Error (MBE) and Root Mean Square Error (RMSE). The result shows that there is a considerable forcing on climatic parameters in Nigeria with relative humidity receiving the lowest percentage of forcing and rainfall having the greater percentage of solar forcing and that there is a direct forcing on temperature and an inverse force on precipitation.
