!!!MJO index (updates on 11:50 every day)

* '''[[Index 1|]]''' ([[Taniguchi et al., 2010|]]) defined by EOFs of velocity potential (30N-30S) at 200-hPa ('''Only 92 days earlier. Not Real-time''')
** DATA source for calculation: velocity potential at 200-hPa produced by [[JRA-25/JCDAS products|]] of the project on collaboration between [[Japan Meteorological Agency (JMA)|]] and [[Central Research Institute of Electric Power Industry (CRIEPI)|]].

* '''[[Index 2|]]''' (Wheeler and Hendon, 2004) defined by EOFs of the combined fields of near-equatorially-averaged 850-hPa zonal wind, 200-hPa zonal wind, and satellite-observed outgoing longwave radiation (OLR) data ('''Only 2 days earlier''')
** DATA source: An All-season Real-time Multivariate MJO Index (Wheeler and Hendon, 2004) produced by [[Bureau of Meteorology Research Centre (Australia)|]]
