Abstract. Hurricanes are complex systems that carry large amounts of energy. Their impact produces, the majority of the time, natural disasters involving the loss of human lives and of materials and infrastructure in billions of US dollars. However, not everything is negative, as hurricanes are the main source of rainwater for the regions where they develop. In this study, we perform a nonlinear analysis of the time series obtained from 1749 to 2012 of the occurrence of hurricanes in the Gulf of Mexico and the Caribbean Sea. The construction of the hurricane time series was carried out based on the hurricane database of The North Atlantic-basin Hurricane Database (HURDAT), and the published historical information. The Lyapunov exponent indicated that the system presented chaotic dynamics, and the time-series’ spectral analysis along with the nonlinear analysis of the hurricanes time series showed chaotic edge behavior. One possible explanation for this edge is the individual chaotic behavior of hurricanes, either by category or individually, regardless of their category, and their behavior on a regular basis.
