Query: On the correlation between air temperature and the core Earth processes:
  Further investigations using a continuous wavelet analysis   In a recent article by Dickey, J. O., Marcus, S.L. and O. de Viron, 2011, the
authors show evidences for correlations in the multi-decadal variability of
Earth's rotation rate [i.e., length of day (LOD)], the angular momentum of the
core (CAM), and natural surface air temperature (SAT). Previous investigators
have already found that the LOD fluctuations are largely attributed to
core-mantle interactions and that the SAT appears strongly anti-correlated with
the decadal LOD. As the above authors note, the cause of this common
variability needs to be further investigated and studied. In fact, "since
temperature cannot affect the CAM or LOD to a sufficient extent, the results
favor either a direct effect of Earth's core-generated magnetic field (e.g.,
through the modulation of charged-particle fluxes, which may impact cloud
formation) or a more indirect effect of some other core process on the
climate-or yet another process that affects both". The main aim of the present
research note is to further support the above results, using a proper
continuous wavelet analysis, and to evidence some early detected time-period
relations existing between LOD and SAT data.
