So, as we discussed in class, the site that we normally use to host the powerpoint files for this class has gone out of business.  Rats.  In the meantime, there are only a couple of powerpoint files associated with this unit of material, so here they are:

• Intro to El Nino
• The Canonical El Nino
• Global Impacts of El Nino
• El Nino in the US
• The QBO
• The MJO
