Beschreibung:
The effect of variable solar activity (on the 11-year solar cycle time scale) on surface temperature at Toronto has been evaluated for three recent decades. For this data segment, it is highly probable that variable solar activity did influence climate and that the effects for the three decades were often significantly different. These inter-decade differences in solar effects were not random, but were organized in a coherent pattern in time. This pattern was substantially independent of season, climate parameter or statistical test, although there were major seasonal variations in the relative magnitude of modulated solar effects compared to unmodulated solar effects. The inter-decade variability had a maximum in spring and a minimum in autumn; on the other hand, the net effects of solar variability (ignoring interdecade variations) were weakest in spring and strongest in autumn. © 1991, Society of Geomagnetism and Earth, Planetary and Space Sciences.
