Abstract
Applying spectral analysis to the Atlantic and Pacific hurricane time
series, we found periodicities that coincide with the main sunspot and
magnetic solar cycles. To assess the possibility that these
periodicities could be associated with solar activity, we obtain
correlations between hurricane occurrence and several solar
activity-related phenomena, such as the total solar irradiance, the
cosmic ray flux and the Dst index of geomagnetic activity. Our results
indicate that the highest significant correlations are found between the
Atlantic and Pacific hurricanes and the Dst index. Most importantly,
both oceans present the highest hurricane–Dst correlations during the
ascending part of odd solar cycles and the descending phase of even
solar cycles. This shows not only the existence of a 22 yr cycle but
also the nature of such periodicity. Furthermore, we found that the
Atlantic hurricanes behave differently from the Pacific hurricanes in
relation to the solar activity-related disturbances considered.

Conclusions
Applying wavelet spectral analysis to the hurricane time series, we
found periodicities that coincide with the main sunspot and magnetic
solar cycles. In the Atlantic Ocean there are peaks near 11 and 22 yr.
The Pacific Ocean time series is not long enough to allow the
identification of the 22 yr cycle, however the 11 yr cycle clearly appears.
Using superposed epoch analysis to investigate the nature of the 22 yr
cycle in hurricane occurrence, we found that the highest significant
correlations
