Influence of global warming on water requirement of agricultural areas and forests
- Rutgers-the State Univ., New Brunswick, NJ (United States)
In the present study, a mesoscale atmospheric numerical model with a grid resolution of a few kilometers and a sophisticated parameterization of subgrid-scale heterogeneities of land surface characteristics is adopted to evaluate the water requirements of agricultural and forested areas under different global warming scenarios. With this subgrid-scale parameterization, a surface resolution of a few meters is virtually achieved. Interactions between ET and thermally induced mesoscale circulations generated by different areas with different degrees of dryness and/or plant stress are described. Global warming scenarios produced from GCMs are used to drive the mesoscale model. The coupling of a GCM with the mesoscale model is very appropriate since the entire domain simulated by the mesoscale model can be set to simulate the domain represented by one single grid element of the GCM. Thus, together, the two models can be used in a hybrid from to predict atmospheric conditions at the scale of a few meters of complex terrain within larger synoptic-scale atmospheric flow regimes.
