Auwal Garba

ABSTRACT

The study looks into changes in meteorological factors in the study area as well as annual trends of climatic variables. Temperature, precipitation, and sun radiation were examined as weather variables. The Nigerian Meteorological Agency provided meteorological parameters for the time period (1982–2017). The meteorological parameters that were acquired demonstrated patterns of variability for each parameter with regard to the given period when trends analysis of previous and contemporary variations were used. For the analysis of the collected data, a linear trend model was applied.The analysis’s findings indicate that both the minimum and maximum temperatures gradually increased (from 200°C to 230°C and 320°C to 340°C, respectively), while rainfall steadily decreased (from 118.7 to 174.4 mm annually) during the study period and solar radiation gradually increased (21.8Mj/m2 to 19.4 Mj/m2) over the course of the time period.
