Responses of Surface Evaporative Fluxes in Montane Cloud Forests to the Climate Change Scenario

Abstract Fog plays a vital role in maintaining ecosystems montane cloud forests. In these forests, large amount of water on the surface leaves and canopy (hereafter water) evaporates during morning. This biophysical process critical factor regulating afternoon fog formation. Recent studies have found that alterations precipitation, temperature, humidity, CO 2 concentrations associated with future climate changes may affect terrestrial hydroclimatology, but responses forests remain unclear. Utilizing numerical experiments Community Land Model, we explored evaporative fluxes Chi-Lan Mountain northeastern Taiwan under RCP8.5 scenario aforementioned various atmospheric variables. The results showed increased rainfall intensity change runs decreased accumulation water, while larger vapor led to more nighttime condensation leaves. Elevated did not greatly impact amounts, photosynthesis was enhanced, transpiration reduced contributed latent heat fluxes, implying importance forest plant physiology modulating land fluxes. Evapotranspiration due multiple combined factors, contrast expected intensification global cycle warming. study, however, is restricted an offline model without land–atmosphere interactions adjacent grids, which deserves further analyses for regions.
