L. LEMUS, CARLOS GAY

Abstract

In order to study the temperature and precipitation variations for the state of Aguascalientes, Mexico (22º, 2' N Lat, 102ºW Long), seven meteorological stations data are analyzed. The recorded data are for periods between 1921 to 1985. The possible local effects associated to these variations are studied by the aridity index and productivity (biomass) behavior. The results show an average increase of temperature in the state of T = 0.4ºC. This increase coincides with the general global warming trend reported by Jones et al. (1986). We also found an increase in the aridity index and a reduction of the productivity (gr/m2 year) of the state.
