ABSTRACT

Rind 1984

Rind, D., 1984: The influence of vegetation on the hydrologic cycle in a global climate model. In Climate Processes and Climate Sensitivity, AGU Geophys. Monograph 29, Maurice Ewing Vol. 5. J.E. Hansen and T. Takahashi, Eds. American Geophysical Union, pp. 73-91.

The influence of plants on climate has many different aspects. Plants affect the surface albedo, the water holding capacity of the soil-vegetation system, the transport of water from deeper levels within the ground, the roughness of the surface, and the influence of snow cover on albedo. The first three of these characteristics are investigated in a global climate model (GCM) by removing each influence individually over all land grid points. Each experiment was run for two years and compared with a control run of five years. The results indicate that the effect on surface albedo and on water holding capacity are of similar magnitude in the model but maximize in somewhat different regions. The albedo effect is most important in areas with plentiful moisture associated with evaporation off ocean surfaces and in seasons when large-scale dynamics or convection controls rain production. The water holding capability influence dominates where local evaporation is essential for precipitation. The transport of mositure within the ground affects the phase of water loss in most areas. These experiments emphasize the importance of vegetation in global climate system. The also indicate the importance of including full seasonal cycles in the estimation of climate change with vegetation removal.
