Finally we propose possible physical causes of the latter historical switch from sinusoidal state to node–antinode state.    From Wordnik.com.  [Unthreaded « Climate Audit] Reference

By its very nature, this imminent node–antinode state is expected to make global temperature vary significantly above and below a common mean which itself may be approximately constant or may at certain times undergo relatively slow drifts.    From Wordnik.com.  [Unthreaded « Climate Audit] Reference

A previous publication by the author predicted that global temperature patterns will switch from the sinusoidal (amplitude-modulation) state into which it has been since 1944 into a node–antinode (amplitude-modulation) state somewhere over the 1997–2012 period.    From Wordnik.com.  [Unthreaded « Climate Audit] Reference

Furthermore we present a historical example in which records of temperature-sensitive indicators show that at least some regional temperature patterns have at least once switched from the sinusoidal amplitude-modulation state to the node–antinode state under global climate conditions that were fairly similar to those of the present.    From Wordnik.com.  [Unthreaded « Climate Audit] Reference
