One of our associated teachers has put together an excellent summary of the El Nino Southern Oscillation and how it affects the rest of the world at http://rgsweather.com/2015/11/01/el-nino-how-does-it-impact-uk-winter-weather/.
We’ve also got a list of other useful links and there have been some lovely images recently of the Atacama desert in bloom as a result of increased El Nino related rainfall in South America.
