The Impacts of Multiple Simultaneous Climate Variations
Climate variationssuch as El NioLa Nia (ENLN), the MaddenJulian Oscillation (MJO), and the Arctic Oscillation (AO)have significant impacts on environmental conditions and operatingenvironments around the globe. However, relatively little is known about how climate variations interact and alter each...

Climate variationssuch as El NioLa Nia (ENLN), the MaddenJulian Oscillation (MJO), and the Arctic Oscillation (AO)have significant impacts on environmental conditions and operatingenvironments around the globe.

We used several multi-decadal reanalysis data sets to investigate the interactions between ENLN and MJO events. We analyzed the interactions by season, and by event amplitude and phase.
