Analysis of the temperature changes in the Aburra Valley between 1995 and 2015 and model based on
urban, meteorological and energetic parameters
Enrique Posada, Andrea Cadavid and David Robledo
INDISA-HATCH, Colombia
There is a perception among the inhabitants of the Aburra Valley Region, that the zone has been suffering big temperature
raises in the last years, especially in the last decade. To give perspective about this issue, the authors have gone through
the available information about temperature changes on three meteorological stations and have correlated it with a set of
variables of urban, climatic and energetic nature with the intention of developing an approximate model to understand the
temperature changes. Raises in the mean temperature, based on the linear tendencies were estimated on 0.47°C for the 20 years
between 1995 and 2015; 60% of the raise is due to the local activity and 40% due the impact of global warming. Nevertheless
it is a complex behavior, which has oscillations. In order to visualize and model the changes, it was necessary to linearize the
behavior and understand the relation between the measuring stations, its geographical position and their altitude above the
sea level. On the most representative station of the urban impact, the linearized temperature behavior was correlated with the
mentioned variables. The differences between the temperatures and their linearized changes were acceptably correlated with
global and local climatic influences. Significant results allowed understanding the city impact and its energetic performance
on the temperature.
