| Zusammenfassung |
| Beginning from the 1950's, Paluš and Novotná (2009) observed statistically
significant phase coherence among oscillatory modes with the
period of approximately 7–8 years detected in monthly time series
of sunspot numbers, geomagnetic activity aa index, North Atlantic
Oscillation (NAO) index and near-surface air temperature from
several mid-latitude European stations.
Focusing on geographical distribution of the phenomenon
we study Northern Hemisphere patterns of phase coherence between
solar/geomagnetic activity and NCEP/NCAR and ERA40 near-surface
air temperature. Both the reanalysis datasets provide consistent
patterns of areas with marked phase coupling between
solar/geomagnetic activity and climate variability observed in
continuous monthly data, independent of the season, however,
confined to the temporal scale related to the oscillatory periods
about 7–8 years. |
