ISLA DE CALOR Y SU INTENSIFICACIÓN EN LA VIVIENDA PERIFÉRICA DE MÉRIDA HEAT ISLAND AND ITS INTENSIFICATION IN THE PERIPHERAL HOUSING OF MÉRIDA

Abstract

Extreme temperatures and heat waves trigger considerable problems to the population and the environment, making the inhabitants of urban areas the most vulnerable to this situation. The impacts generated are identified from a general increase in the demand for water and energy, health problems and greater air pollution. In this sense, the influence that cities have on their own climate has long been recognized, which is typically hotter than its nonurban surroundings, this phenomenon is called Urban Heat Island (ICU), and its main causes are due to the urbanization process. One of the mitigation measures is the increase in intraurban vegetation areas; You are filtering the wind currents, decrease the air temperature through evapotranspiration and intercept solar radiation before being absorbed by the waterproof materials of the city. This work explores the intensification of the UHI in the city of Mérida, Yucatán. Its objective is to determine the thermal behavior of the housing areas on the periphery of the city and conurbation. On the one hand, the results obtained show the convenience of the methods used to characterize the problem, on the other, they reveal that the housing sectors located on the periphery have temperature patterns that range between 47 and 55 degrees Celsius. The above reflects the need to establish land use policies and housing development, contributing to the process of adaptation to climate change.
