I recall reading a paper a while ago that presented the initiators of a number of El Nino events, but I can't recall its title. I want to say the paper dealt with the models used to predict ENSO events, and since there were a number of initiators, forecasting was problematic.<br /><br />Sorry.Bob Tisdalehttps://www.blogger.com/profile/15462377647970214137noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-60047456812524880092009-12-29T15:04:20.766-05:002009-12-29T15:04:20.766-05:00Just stopped by to assist with your "hit envy...Just stopped by to assist with your "hit envy."

The 1986 portion of it was an El Nino Modoki:<br />http://i32.tinypic.com/24bqae0.png<br />And in 1987, the El Nino Modoki Index just squeaks into El Nino Modoki territory.<br /><br />Looks like I’ll have to go back and change the wording regarding the step changes from “significant traditional El Nino events” to “strong El Nino events.”<br /><br />Will the 2009/10 El Nino also cause a step change?

It didn't look like it from the graph I saw in your initial Modoki post (in fact the Modoki index seems strongly negative for some of the step-change events).<br /><br />Just curious if you think if the Modoki factor plays an influence in the step-change nature of an El-Nino.Johnnoreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-17172050469651354492009-12-28T12:06:45.704-05:002009-12-28T12:06:45.704-05:00Anonymous 11:35AM: You asked, "What about the...Anonymous 11:35AM: You asked, "What about the El Niño Modoki index?
