Northeast Pacific annual accumulated cyclonic energy rank-profile

摘要

The ranking of events is a powerful way to study the complexity of rare catastrophic events as earthquakes and hurricanes. Hurricane activity can be quantified by the annual accumulated cyclone energy index (ACE), which contains the information of the maximum sustained wind speed, duration and frequency of the tropical cyclone season. Here, the ranking of the Northeast Pacific annual ACE is obtained and fitted using nonlinear regression with several two- and three-parameter ranking laws that fit the tail and head of the data, where lives the information of relevant events for human society. The logarithmic like function k - a log(n) + b log(N + 1 - n) overperforms all other fits. A sliding window analysis of the parameters a and b of such a function shows that forcing and dissipation processes are anticorrelated.
