1.   But a feature of each solar cycle is that the magnetic poles reverse.

2.   In summary, our results provide circumstantial support for the hypothesized link between solar cycle length and irradiance.

3.   The maximum in the current solar cycle has passed, but both solar and geomagnetic activity remain high.

4.   Another possible mechanism is not light from the Sun but rather its winds of particles and magnetic fields, which change dramatically in strength during the solar cycle.

5.   Back then the main cause of warming was probably the solar cycles.

6.   He also considers the number of past storms that occurred in various areas during similar stages of the solar cycle.

7.   Tinsley found clear links between this mechanism and the paths and intensity of severe winter storms during the solar cycle.

8.   When the solar cycle peaks again next year, however, utility companies will be prepared.

9.   Among the revelations are detailed studies of the phases of the moon during three solar cycle.
