Escenarios climáticos futuros para Paraguay

were estimated future climate scenarios of temperature, precipitation, especific humidity and solar radiation for the region centered on paraguay. four global climate model outputs (hadcm3, echam5, gfdl 2.0 and csiro-mk3 ) were used, for 2020, 2050 and 2080, with socioeconomic scenarios sres a2 and b2. there is a significant differences in the precipitation estimatives, the greatest reductions (-6%) would be located over paraguay river basin and the largest increases (+5%) in the eastern region. the future temperature change scenarios show a warming of 1° c by 2020, 2.5 ° c by 2050 and +4.5 °c by 2080. the greatest warming could be verified over the paraguay river basin and minors over the southeastern. the specific humidity could be increased over the entire region +0.2 gr/kg by 2050 and +0.3 gr/kg by 2080. the major increase could be occurring on rio paraná basin. an increase in solar radiation could be occurring over the bolivian altiplano and a decrease in the southwestern region. with the precis system v1.6 we developed future climate scenarios in high resolution for the period 2081-2090, increase in annual average temperature +2° c would be expected over paraguay.
