The influences of global climate change oil sensible and latent heat fluxes of maize were Studied by using, file Simulation model of Goudriaan (1977). Fight scenarios were made, all increase of CO(2) content until doubling the recent content was included in the scenarios. Some of the scenarios were developed by downscaling the IPCC (2007) report (A2 and B2) to Hungary, and the others by taking into account more Serious weather changes. surprisingly, the distribution of intercepted radiation among sensible and latent heat fluxes ill file individual scenarios was not significantly modified. A given increase in ambient air temperature caused a lesser rise in crop temperature at cob level, demonstrating the compensation role of the canopy. The moderate rise in crop temperature indicated that the plains did not suffer significantly from lack of water in any of the scenarios. However, there was a variation during the diurnal cycle. The doubled CO, concentration alone increased the net carbon assimilation rate of maize by 40%. Photosynthesis decreased only in cases with warmings higher than 6 degrees C. Decreased precipitation counteracted the Positive influence of elevated CO(2) on carbon assimilation. In other scenarios the latent heat flux increased in comparison to control run. This justifies the existence of reserve soil water at Keszthely, even in on extra hot day during July.
