This study was about Identifying climate change, by adopting the downscaling techniques in Umuahia metropolis. The study adopted ex-post-facto research design and data for maximum and minimum temperatures were collected from the archive of NIMET and for the period 1986-2015. On the other hand large scale predictor’s data were collected from the archive of HadCM3 for these periods 1960-2001 (NCEP) and 1960-2099(HadGCM3). Analyses were done using SDSM, ANOVA, PPMC and MLR. The study unraveled that, Mean sea level pressure (MSLP), Relative humidity at 500 hpa (r500), Relative humidity at 850 hpa (r850), and Temperature at 2 meters above sea level (temp) are the predictors of minimum and maximum temperature in the area. This also showed statistical significance at P<0.05. During validation the monthly sub-model performed better by using these indices for minimum and maximum tempe.. View More»
