<![CDATA[Research has been conducted on the influence of the Madden Julian Oscillation (MJO) phenomenon of rainfall anomalies in Bali Province since 1991-2020. Research aims to figure out the conditions, anomalies, and frequency distributions rainfall in Bali Province during the existence of MJO’s 4 and 5 phase for 1991-2020 a descriptive statistical methods.
