46-60 Ernesto Jáuregui Impact of land-use changes on the climate of the Mexico City Region Ernesto Jáuregui* Recibido: 17 de junio de 2004 Aceptado en versión final: 21 de septiembre de 2004 Abstract.
It is well established that anthropogenic land-use changes directly affect the atmospheric boundary layer at the mesoscale dimensions.
Located in the high lands of Central Mexico, the basin of Mexico (7 500 km2) has undergone a widespread conversion of natural vegetation to urban and agricultural land by deforestation.
While the urban extension of the capital city occupied 6% of the basin in 1960, at the end of the twentieth century the urban sprawl had increased considerably to 20% of the total area.
This phenomenal growth has impacted on the thermal climate of substantial portions of the basin.
In this paper using annual temperature and precipitation data for a 25 year period, an attempt is made to identify interdecadal climate changes.
Results show that large areas of the basin have changed toward a warmer drier climate.
While afternoon temperatures have increased at a rate of 0.07° C-yr in the suburbs of the city the corresponding area averaged value for the rural sites is somewhat less: 0.06° C-yr.
