I was reading about tropical cyclones and tropical waves and there I saw a study mentioning its relationship with MJO activities. I saw several research papers which discuss about MJO waves. They only mention that a rising sinking pattern travels eastward at a given speed every 40-60 days.

I could not find any detailed mechanism about how these waves are generated near Africa and Western Indian Ocean. How is the wet-dry pattern formed? Does it have any relation with the high radiation in Northern hemisphere summers? If there is any, do these waves emerge during Southern hemisphere summers too?

    $\begingroup$ well if you can solve it you can earn yourself the en.wikipedia.org/wiki/Carl-Gustaf_Rossby_Research_Medal :) $\endgroup$ – gansub Oct 10 '18 at 14:24

    $\begingroup$ The origin of MJO is a mystery unsolved so far. Theories about it abound though - from mid latitude influences to Kelvin wave interaction etc but none convincing yet though $\endgroup$ – gansub Oct 10 '18 at 14:25

    $\begingroup$ @gansub maybe you can add an answer summarising the remaining problems and where the current research stands? $\endgroup$ – Gimelist Oct 12 '18 at 22:08
