In all nine stations daily climate data were collected from NMSA and aggregated to monthly. The monthly rainfall was varied and distributed moderately on annual and seasonal basis in all stations. The occasion of onset dates are slightly increasing (delaying) for both stations toward the recent years. The end dates of the growing season were decreasing at Wolayta station and very slightly increasing at Bilate station. The interannual variability of length of growing season for both the stations was low. In both the stations, the dry spell length probability of longer than 5, 7 and 10 days were decreasing from the starting date of the growing season to the middle of Belg season and increasing towards the end of Belg Season. SDSM is applied in order to downscale the climate variables at the station level. Under A2 scenario, SDSM indicates an increase in th...
