Abstract:
Self-organization and criticality in hurricanes
Tropical cyclones, or, roughly speaking, hurricanes, are complex
structures that have been studied for a long time; nevertheless, many
aspects of the physics of hurricanes remain unknown. For instance,
although there have been substantial improvements on the prediction of
their trajectories, the sudden intensifications that they experience
preclude the possibility of obtaining reliable forecasts.
We analyze different measures of hurricane size, trying to establish
connections with out-of equilibrium critical phenomena. Moreover, this
new perspective can help to understand
the complexity of climate-change processes.
