The evolution of the 2015 Belg season began with large delays to the start of the rainy season and greatly suppressed precipitation during March-April. Satellite derived products including the African Rainfall Climatology V2 (ARC2) data and vegetation indices, reanalysis data, and other datasets are used to study the dynamics associated with the Belg rains. In many parts of the Oromia, Afar, and Somali provinces, the start of rains was delayed by 4 weeks or more. March-April ranked in the lowest 3% of the past 32 years, with less than 25% of normal rainfall observed during the period. Anomalous northerly low level winds were dominant over Ethiopia during this time. Rainfall then increased during May as a result of changes in dynamical conditions, moderating seasonal deficits. The increased rainfall during May resulted in moisture surpluses for the month. ARC2 rainfall ranged from 150% to more than 200% across north-central Ethiopia. An anomalous southerly flow brought moisture from the Indian Ocean into Ethiopia during this period. However, relief was too late for the majority of crops and some livestock to which the damage had already been done. The influence of the NAO and an active MJO on the 2015 Belg rains is studied and presented.
