Abstract

The Madden'Julian oscillation (MJO) plays a critical role in connecting or bridging weather and climate. Its large-scale signals in the atmospheric circulation, deep convection, and other variables propagating eastward slowly from the Indian to Pacific Oceans are the dominant component of the tropical intraseasonal variability. The MJO is involved in scale interactions across a wide range of spectrum from the diurnal cycle to interannual variability. The MJO is a prominent source of the monsoon intraseasonal fluctuations. It affects the Asian summer monsoon mainly through, in addition to its eastward propagation, its northward propagation, which is unique in boreal summer. The MJO affects the Australian monsoon as its convection center propagates eastward, passing over the northern part of Australia. MJO influences on precipitation extend to extreme rainfall, defined as precipitation breaking the records or within a given top percentile.
