Tendencia de la dinámica no-lineal en una precontingencia ambiental causada por partículas en suspensión

Abstract

The trend of the indexes of the nonlinear dynamics in an environmental pre-contingency by particles PM 10 in the Metropolitan Area of Mexico Valley was found. The tools of chaos theory were applied to determine the dynamic behavior coincidences and the study period from December 15 to January 7 was selected. The indexes of nonlinear dynamics were calculated to evaluate the changes in the dynamic behavior and the attractors in the phase space were plotted. The results obtained in terms of persistence, divergence and autocorrelation vary depending on the concentration of PM 10. The Hurst exponent allowed finding the best concordance with PM 10 and it was observed that when it exceeds the value of 0.3 the probability of reaching a pre-contingency event increases.
