I really should do more of these since LJ has been a pretty good way to track changes over time. My loyal readers should know that I love to spend as much time as I can outside. Now that we're getting high temps in the 70's, I've been spending more and more time out on the patio. That also means grilling season! Steaks tonight! But back to science. Yesterday I noticed that my ash tree started leafing out. I hope to post simple observations like that to see if 10 years from now that date is weeks earlier or about the same. I have been doing my own study at work since I have 50+ years of streamflow, weather, and snowpack data at my fingertips. I have been pouring over the numbers to see if there are any discernible weather/climate trends. So far I have found a weak correlation in earlier S.A.G. dates (remember that term, kiddies? Snow All Gone) I'm finding it difficult to correlate earlier peak runoff dates over time because there are so many other factors involved. Likewise it's hard to make a direct correlation between snowpack and runoff because antecedent conditions seem to play an important role. Then there are wild cards like increased sublimation due to hot, dry winds. Am I boring you with this? Science!
