NOTE: As of Spring 2011, the exercises built for this website (originally created in 2002) are no longer functional due to the evolution of our server infrastructure that supports this and many other CCNMTL websites. We have left the instructional text so that you can see what was provided at the time as a reference. We regret any inconvenience and would encourage you to explore other tools such as the KNMI Climate Explorer that will allow you to actively explore seasonal climate prediction further.
