This Week's Ticker: Lather, Rinse Repeat

If the Ticker seems a bit repetitive this week, it's for a reason:
we come from the School of Redundancy School when it comes to topics.

Today, we'll look at our month-to-month correlations, again. Except
this time we'll look at persistence in a single variable. Today's
graphic looks at persistence in temperature. Specifically, it
addresses the question: how much are one month's temps influenced by
the previous month's temps?



In Oklahoma, summertime is persistence time. This graph clearly
shows that temperature gathers some inertia through the summer
month's, coming to a maximum in August's sensitivity to July.
So, all other things being equal, a hot July is a useful (but not
the only) predictor of a hot August.

Most of the rest of the calendar shows positive-but-nearly-negligible
correlations. In other words, one month's temp barely influences the
next month's temp.

Interestingly, April and December showcase correlations that indicate
an ever-so-slight tendency to "flip" the previous month's temperature
results. However, the correlations are so minuscule that they are
probably meaningless.
