On the Recent Climatological and Energy Trends in Mexico City

This is a first report of a comprehensive effort to determine the nexus between energy demands, population growth, and a changing climate for Mexico region. We first report here Mexico City climatology, trends in temperatures, heat index and heat waves registered in the Valley of Mexico and its potential relation to electricity consumption. The work is motivated by the environmental impacts that densely populated cities such as Mexico City produces manifested by energy consumption and emissions to the environment and direct consequences in the quality of its inhabitants and on the local environment. We used eight weather stations spread over the valley of Mexico to analyze temporal trends of maximum and minimum daily temperatures and relative humidity. The heat index and the human discomfort index are derived as tools to determine trends in environmental variables that may be linked to energy demands in the Valley. The actual power consumption in the valley of Mexico are further analyzed for formulating relationship between power consumption and maximum temperatures during long-term scenarios and during specific extreme heat events. The relationship between power consumption with changes in the population in the valley of Mexico is also investigated.
