Hey folks- hope this is the right place to post this- I'm new here so if not don't be too harsh on me.
Anyways I am about four years out of my grad program and my once (relatively) vast stats background has began to fade since I haven't really been using anything since graduation.
I have taken up a project purely for fun to see if I can uncover some relationships between local climate / hydrologic function. Specifically, I am trying to correlate annual water levels in a local reservoir and PDO (Pacific Decadal Oscillation) and AMO (Atlantic Multidecadal Oscillation) fluctuations, and / or annual precip & temperature values. We are currently in a severe drought (SW Colorado), and improper management (IMO) of the local water resources over the past few years has exacerbated the problems. Now our local reservoir is about to hit its lowest low since it was filled in 1987, with no respite in view. As mentioned I have annual data from the reservoir level (in pool elevation ft), as well as index values for the AMO & PDO for the same time period. Hypothesis is currently that drought conditions ensue in this region when the PDO is negative, and the AMO is positive. I also have access to precipitation totals, and average temperatures for the study years (1987-2013) if needed. With the relatively short data period (26-27 years)- what would you do to draw relationships and conclusions here? I can attach the raw data in a spreadsheet if anyone would like to view it. Any help you guys can offer would be tremendously helpful and appreciated.
