Biography

Abstract
We present the results of the time series analysis of occurrence of hurricanes and sunspots from 1749 to 2012. Exploratory analysis shows that hurricane numbers is declining in total number by year. This decline in the number of hurricanes is related to an increase in the sunspots activity. Spectral analysis shows a relationship between the hurricanes oscillation periods and the sunspot cycles. Several sunspot cycles were identified from the hurricanes time series spectral analysis the most conspicuous being the 4, 11, 22, 60 and 80 year’s cycles; and a 30-year that is related to cosmic rays cycle. The relationship between hurricanes and sunspot is both direct and inverse; the combination of the observed cycles produces seasons in which the number of hurricanes are in phase with sunspots and others which are out of phase.
