Coupled climate–carbon cycle models suggest that global warming will act to ...Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0894Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract Changes in land surface driving variables, predicted by GCM transient climate change experiments, are confirmed to exhibit linearity in the global mean land temperature anomaly, ΔT l . The associated constants of proportionality retain spatial and seasonal characteristics of the GCM output, whilst ΔT l is related to radiative forcing anomalies. The resultant analogue model is shown to be robust between GCM runs and as such provides a computationally efficient technique of extending existing GCM experiments to a large range of climate change scenarios. As an example impacts study, the analogue model is used to drive a terrestrial ecosystem model, and predicted changes in terrestrial carbon are found to be similar to those when using GCM anomalies directly.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1472Keywords: Orography ; Planetary boundary layer ; Atmospheric feedback ; Surface resistanceSource: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract The effect of orography on the spatial variability of surface evaporation is studied numerically for two hill heights and two prescribed forms of surface resistance. A numerical model of the planetary boundary layer carrying scalars of temperature and specific humidity, and with a surface energy balance scheme, is employed. It is found that the difference in mean evaporation between model runs with hills and analogous runs for flat terrain may be explained primarily by an increase in surface area and adiabatic cooling at the hill surface.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1472Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract Three models of the partitioning of net radiation into latent and sensible heat fluxes over Sahelian savannah are described. Each model has a different configuration of stomatal and aerodynamic resistances. Their performance was assessed by comparison against field measurements of latent heat flux over savannah vegetation consisting of bushes interspersed with a herbaceous understorey. The modelled results indicate that in dry conditions, a Penman-Monteith based single source model performs adequately when predicting the latent heat flux. However, the models with two sources demonstrate that the bushes and herbs have very different responses to local climate. In all the models, evaporation is highly sensitive to stomatal resistance, suggesting that a better understanding of stomatal response would improve the accuracy of the models.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1472Keywords: Atmospheric boundary layer ; Diurnal variability ; Latent heat flux ; Priestley-Taylor coefficient ; Surface resistanceSource: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract Daily mean values of the Priestley-Taylor coefficient, α¯, are derived from a simple model of the daily growth of a convective boundary layer. For a particular control set of driving environmental variables, α¯ is related to the prescribed bulk surface resistance, rS by 1/α¯ = 1/α0 + mrS for parameters α0 and m. The dependence of the parameters α0 and m on weather is explored and a potential use of this linear relation to provide information about regional values of rS is indicated.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1472Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract The Penman-Monteith Big Leaf Model is expressed in terms of eight similarity variables. A simple relationship is derived relating these nondimensional variables to the inverse of the Monin-Obukhov length, L, multiplied by height. Placing this surface energy balance model within such a framework may be of use when coupling to atmospheric models where similarity variables have already been defined.Type of Medium: Electronic ResourceURL:
