Author(s): Dagnew Yebeyen* and Sileshi Nemomissa
A good characterization of time series rainfall and temperature trends, variability and prediction is necessary for many studies in climatology, hydrology, agriculture and forestry. It provides input for policymakers and practitioners that help to make informed decisions and allows the identification of deviations due to global climate change. This study quantified trends and variability in monthly, seasonal, and annual rainfall and temperature in Andracha district, Southwestern Ethiopia, over a 31-year period (1987 - 2017) and provided predictions for fifteen years, up to 2032. The Mann-Kendall test and Sen’s slope estimate were applied to identify the trends and magnitude over the time series. A prewhitening approach was applied to eliminate serial correlations in the rainfall and temperature data. Autoregressive, integrated, and moving-average (ARIMA) modeling was applied for.. View More»
