where to find historical EPO/WPO data?

[powerstate]

Does anyone know how to find historical EPO/WPO data to most recent date as possible? NOAA website has data only up to september 2012 though. I wonder whether there is a place for most recent data.

 

Thanks.

Thank you. That is very helpful! Is there a place to find historical MJO phase data? Something like 3,2,2,2,1.... etc.

Thanks again.

 My initial quick look at looking at the linked EPO and WPO daily readings suggests to me a pretty strong correlation between the EPO and WPO. Does that seem right?

EPO and WPO do look highly correlated. Thank you all for sharing the links.

Also, could anyone help explain the mechanism how MJO dynamics can change EPO/WPO and whether there is a lag? It seems more activity on MJO reduces negative EPO.
