Sensitivity tests with a biosphere model based on BATS, suitable for coupling with a simple climatic model

Abstract

z is inserted in the expression that gives the fractional area of the leaf canopy cover by water in order to take into account the effect of the part of vegetation predominantly porous. The lower values of give better results regarding the component terms of the evapotranspiration. However, the total flux of water vapor to atmosphere does not change with . Sensitivity tests are made with respect to the factor Y introduced in the expression of the water vapor flux to the atmosphere in order to adjust the partitioning of the available energy into latent and sensible heat. The results show that the latent (sensible) heat increases (decreases) with the increase in Y. Although the variation of Y modifies the Bowen’s ratio there is no change of the evapotranspiration partitioning into its components.]]>
