MJO Analysis

[J10]

MJO (or to give the proper title the Madden Julian Oscillation.) is often discussed on this forum, and I think many people would wish to find out more about how it works, I certainly do.

 

If we take today as an example. This is the current 500mb Chart [06Hz]

 

 

Here is the Current MJO Pattern -> (source link) http://www.cpc.ncep.noaa.gov/products/precip/CWlink/MJO/whindex.shtml

and the Forecast for the Next 14 days, with a wide variety of models available

 

 

On the 8th May, we were in Phase 1, with most forecasts indicating a move into Phase 2 by today.

 

How does Phase 2 for May correspond to today's weather taken from the reanalyses below.

 

 

and looking forward, what does the rest of May look like given the current MJO forecasts.

 

Further Information Re-analyses of Phases per month

Adrian Matthews has a very good MJO page with detail and animations in an easily understood format.

The situation in the northern hemisphere does not correspond to the real MJO phase of these next time. Phases 1, 2 and 3 are in favor of NAO + but the negative NAO will dominate and which may dominate this month. MJO phase much less impact in summer than winter in Europe
