"CAUSES"

Some of my current [QUESTIONS] about this important section, which I don't understand........YET WHICH I'VE TRIED TO EDIT.....

QUOTE:
Several mechanisms have been proposed where warmth builds up in the equatorial area, then is dispersed to higher latitudes {NORTH?] y an El Niño event. [WHAT MECHANISMS? HOW IS BUILD-UP AND DISPERSAL RELEVANT??]

The cooler area [WHERE IS THAT?] then has to "recharge" warmth for several years before another event can take place.[citation needed]

The Madden-Julian Oscillation is not a cause of the phenomena, but propagates eastward around the global tropics with a cycle on the order of 30-60 days, and may significantly influence the speed of development and intensity of El Niño and La Niña. 2.

Tropical cyclones north and south of the equator that may play a role in ENSO are caused by the westerly flow between the areas of low pressure induced by a Madden-Julian oscillation.[4] [WHAT DOES THIS MEAN??]

Such wind may counteract the typical easterly flows across the Pacific and create a tendency toward continuing the eastward motion.[citation needed] [A COUNTERACTION OF EASTERLY FLOWS CREATES TENDENCY TOWARD EASTWARD MOTION??]

Eastward-propagating oceanic Kelvin waves can be produced by Madden-Julian activity, which may in turn be influenced by a developing El Niño, leading to a positive feedback.[5] [HOW IS THIS PRODUCED, HOW IS THIS INFLUENCED?}
