I'll just explain a little bit about how these normals were looked at. To be able to look at the trends.... We were talking earlier about the Great Lakes and how, yes, you actually need to look over a few decades. These are over 30 years.
What we've wanted to do with these is to say that if over 30 years this is what was a normal trend for an area, then what does this year look like? When you're looking at the lows or the highs and comparing to what was the normal of the 30 years from 1980 to 2010, what does 2014 look like when we're comparing it to those 30 years?
If it's a high or a low, you may want to go in and actually look at the actual data, and then those living in that area can look at whether they need to take measures to adapt. Is the trend going to continue and, if so, do they need to take action? It's really an information tool so that you can know where you would want to start looking at specific issues.
