Abstract: As the drought research serves potential benefits to the management of its allied sectors, it demands research reasons for climate changes over Eastern Africa. The research paper mainly aims to forecast the drought years using WRF model dataset. For selected meteorological parameters, MBE, RMSE and MAE, have been computed and compared to estimate the correlation with the WRF model with Belg season and the Kirmet season in Ethiopia. The research paper discusses various primary causes for the formation of long and large-scale drought in the Arba Minch and Chencha region during the study period 2001-2010. The research expounds how these less to moderate and extreme conditions can be attributed to the combinational occurrence of La Nina with negative and positive Indian Ocean dipole (IOD) and Hybrid El Nino with NAO and ElNino-Modoki. As Ethiopia is a rainy agriculture-based country, the study is promising for the farmer's fraternity in many dimensions including successful drought forecasting.
