LA PRECIPITACIÓN INTENSA VISTA DESDE LA CRITICALIDAD AUTO-ORGANIZANDA Y LAS TRANSICIONES DE FASE CONTINUAS: UN NUEVO ENFOQUE DE ESTUDIO

Abstract

The self-organized criticality (SOC) is a recent proposed theoretical model for complex systems. Critical phenomena occur near phase transitions. According to this theory,when an ordered parameter increases as a power law, a tuning parameter crosses a critical value. When these parameters couple, the critical point becomes an attractor and the result is a SOC phenomenon. As a characteristic, their scale diverge. Although this concept has been applied in many different processes, ranging from geophysics to economy; in meteorology the physical process is still being considered as chaotic systems. In this case the behavior, marked by the quasi-equilibrium (Arakawa and Schubert, 1974) is far from being self-organized, with uncertainties that grow exponentially. In this context, the present review aims to propose an effective formalism to intense precipitation phenomena using SOC and continuous phase transitions theory. We suggested that the achievement of a critical value of water vapor (parameter tuning) generates a continuous phase transition that yields into a regime of strong convection and precipitation (the order parameter), with correlated regions of hundreds of kilometers (Peters and Neelin, 2006b) that follow a power law relation between intense precipitation and water vapor data.
