| Zusammenfassung |
| The solar effects on tropospheric circulation over Europe are investigated
by counting the occurrence of Hess-Brezowsky synoptic types under various
levels of solar activity. Solar minima are accompanied by a lower incidence
of westerly types and a higher incidence of easterly and northerly types.
The types with a northeast and northwest flow are most frequent under a
moderate solar activity. There is a weak tendency towards the anticyclonic
(cyclonic) types to be less (more) frequent under moderate solar activity.
Our results are in accord with previous studies, indicating a strengthened
zonal flow in solar maxima and changes in the modes of low-frequency
circulation variability. The results point to the fact that the effects of
solar activity are not linear. |
