This looks a lot like seasonality.  Perhaps that could aid your searching,
as much has been written, including on this list, on dealing with
Seasonality of data in R.

Without looking, I recall that Shumway and Stoffer cover this topic.

R packages uroot, partsm, and ast may prove useful.  Also the base 'stats'
package contains the function decompose() and a few others for dealing
with seasonality.

Please report back so other can benefit from whatever you figure out.
