The progression of the boreal winter monsoon through the western Maritime Continent as differentiated by ENSO phase

Short summary

Weather forecasters in Maritime Continent countries base their weekly outlooks on the seasonal progression of the monsoon wind systems. The onset of the monsoon was compared between El Niño and La Niña years using satellite sea surface winds. Rather than being delayed throughout the Maritime Continent during El Niño years, the monsoon was seen to arrive faster at and remain longer over the western Maritime Continent, and therefore delayed for the eastern Maritime Continent.
