3/12/2006, 4/26/1984, 4/10/2008 (relative bust) are a few examples.One thing I was really curious about if someone can help me out, what other events have occurred with longwave trough similar to the one being forecasted on the models? I know 4/3/74 and 11/10/02 were ones, but I don't know of any others off the top of my head
