| Zusammenfassung |
| A correlation is investigated between the intensity of the
global electromagnetic oscillations (Schumann resonance) with the planetary
surface temperature. The electromagnetic signal was monitored at Moshiri
(Japan), and temperature data were taken from surface meteorological
observations. The series covers the period from November 1998 to May 2002. The
Schumann resonance intensity is found to vary coherently with the global
ground temperature in the latitude interval from 45° S to 45° N: the
relevant cross-correlation coefficient reaches the value of 0.9. It
slightly increases when the high-latitude temperature is incorporated.
Correspondence among the data decreases when we reduce the latitude
interval, which indicates the important role of the middle-latitude lightning
in the Schumann resonance oscillations. We apply the principal component (or
singular spectral) analysis to the electromagnetic and temperature records
to extract annual, semiannual, and interannual variations. The principal
component analysis (PCA) clarifies the links between electromagnetic records and
meteorological data. |
