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 ni o 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 days and may significantly influence the speed of development and intensity of el ni o and la ni a 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 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 ni o leading to a positive feedback how is this produced how is this influenced
