Analyzing Rainfall Regimes in Port-Harcourt Metropolis using the Downscaling Techniques

Kpang. M.B.T., Weli. V.E.

Abstract: Over the years studies have shown that Climate can alter the operations of basic systems in our environment. Furthermore, the African sub region has been identified in the literature to be one of the regions that will suffer most in the coming decades. This study therefore analyzes rainfall regimes in Port-Harcourt metropolis using the downscaling techniques. Ex-post-facto research design was adopted for this study. Data for large scale predictors (1960-2099) were collected from the archive of NCEP, while Predictand data was sourced from NIMET, and for the period 1987-2016. Data analyses were archived through SDSM and ANOVA. However what was established in the study include that, the HadCM3 is applicable to Rainfall downscaling in Nigerias Niger Delta region; the rainfall amount for the two scenarios have consistently been on the increase; and finally, A2 scenario projected more rainfall amounts that the B2 scenario. The future precipitation will grow more erratic and with some uncertainties; although the trends of rainfall shows that rainfall is on the increase in the area. There is therefore need to adopt a climate plan cum strategy and a coping capacity built, with which to cope with vagaries of rainfall in the coming years.
