View submission: Are snowfall totals independent from one winter to the next?
It seems like they're only checking the correlation for a single year interval, potentially missing periodic features on a longer time frame. Is there any particular reason a region can't repeat its weather features on, say, a three-year sequence rather than a single year sequence?

Multi-year lagged autocorrelation certainly exists. It's just weaker than the single year lagged autocorrelation. I think you're asking if the correlation ever "skips" a year, though, i.e. precipitation for this year is uncorrelated with precipitation from next year, but it is correlated with precipitation two years from now. I am unaware of any climatological process that results in this sort of pattern.
