Abstract

La temperatura del planeta ha cambiado drásticamente en los últimos años, durante el período 2015-2019 se registró la etapa más calurosa jamás observada según la Organización Meteorológica Mundial (OMM). Lo anterior repercute en el aumento del nivel del mar y en general, en todos los fenómenos hidrometeorológicos que generan millones de pérdidas patrimoniales cuando tocan las costas y el interior de un país. El objetivo de este artículo es pronosticar la generación de ciclones tropicales en los océanos Pacifico y Atlántico en el año 2020 mediante cadenas de Markov, debido a que este tipo de sucesos son elementos fundamentales para el cálculo de primas de riesgo en seguros de huracán y otros riesgos hidrometeorológicos. La hipótesis de la que se parte, es que debido al incremento sustancial de la temperatura del planeta, habrá un mayor número de ciclones tropicales y huracanes de mayor intensidad. Se ha seleccionado esta metodología estocástica debido a las características aleatorias y pérdida de memoria de estos sistemas atmosféricos, así como a la posibilidad de construcción de intervalos de confianza para cada estimación. Los resultados empíricos se comparan con las proyecciones estimadas por la Comisión Nacional del Agua (CONAGUA), obteniendo los mismos resultados en ambos océanos. En futuras investigaciones se considera ampliar la investigación a otros riesgos asociados a carteras de bienes asegurables. / The planet's temperature has changed dramatically in recent years, during the period 2015-2019 the hottest stage ever observed was recorded according to the World Meteorological Organization (WMO). The aforementioned affects the rise in sea level and in general, in all the hydrometeorological phenomena that generate millions of patrimonial losses when they touch the coasts and the interior of a country. The objective of this article is to forecast the generation of tropical cyclones in the Pacific and Atlantic oceans in the year 2020 using Markov chains, since these types of events are fundamental elements for calculating risk premiums in hurricane insurance and others. hydrometeorological risks. The hypothesis from which it is based is that due to the substantial increase in the temperature of the planet, there will be a greater number of tropical cyclones and hurricanes of greater intensity. This stochastic methodology has been selected due to the random characteristics and memory loss of these atmospheric systems, as well as the possibility of constructing confidence intervals for each estimate. The empirical results are compared with the projections estimated by the National Water Commission (CONAGUA), obtaining the same results in both oceans. Future research considers expanding the research to other risks associated with insurable asset portfolios.
