Detección de la tendencia local del cambio de la temperatura en México

Abstract

Temperature records indicate that three of the four climatic stations evaluated in Mexico show warming over the years 1950 to 2013, as compared to the period 1961 to 1990 which was used as a baseline. After a complete analysis of climate records in Mexico, only 112 were determined to have met the quality and standards required for the present study. From those, a subset of 20 stations with a positive trend were randomly selected, which were representative of urban and rural areas distributed across Mexico. The mid 1970s was identified as the most recent period of intense warming, which is consistent with the mean global temperature indicated by the Intergovernmental Panel on Climate Change. A 10-year difference in the start of the warming period was found between rural and urban regions in Mexico. Warming and the difference between warm and cold periods are typically greater in urban areas than in rural areas.
