Climate variability, climate change and extremes have received increased attention in recent years, since they can have overwhelming impact on environment and society.The study of climate extremes is rather complex due to the excessive statistical limitations inherent to extreme analysis.Then the analysis is done use precipitation and Temperature extreme events over Ethiopia.The aim of this study is to describe temporal trends in extreme weather events and their spatial distribution in Ethiopia, based on geographic region of the country.In this study daily precipitation, Maximum and Minimum Temperature data for the period between 1975-2010 where used.172 locations where considered for the analysis.We calculated 27 core set of extreme weather indices, for individual stations as well as regions.ReclimDex program was used to perform a bootstrapping procedure to provide cross validation of the values.
