Convection-Permitting Modeling (CPM) captures well localized extreme weather events, and sub-daily precipitation characteristics (diurnal cycle, spatial structures, and extremes). NCAR has been conducting long-term WRF CPM regional climate simulations for North and South America. Better representing complex land-surface processes and land-atmosphere interactions in WRF has significantly improved CPM regional hydroclimate simulations. For instance, incorporating a groundwater model in WRF effectively mitigates dry and warm bias of WRF CPM in Central Plains in the United States. Advancing the understanding of the nexus among food, energy, and water systems has recently emerged as a new science frontier, and the research community started modeling urbanization and agricultural management in earth-system models to develop an integrated modeling tool for investigating relevant land-atmosphere interactions and agriculture and urban sustainability issues. However, despite those efforts, there are substantial discrepancies in simulating land-atmosphere interactions over human-modified surfaces. We discuss recent efforts in developing an integrated urban and agriculture-system model in WRF to highlight the challenges for earth-system models to capture cross-scale interactions between urbanization, agricultural management, hydrology, and climate systems.
嘉宾简介/Speaker
He
is interested in improving land-surface modeling and data assimilation.
Study land-atmospheric interactions and their impacts on boundary layer
structures and precipitation. Examine feedback between soil moisture,
vegetation conditions, landscape change, agriculture management,
urbanization, and regional weather and climate. Organized the surface,
vegetation, and soil observation network for the IHOP_02 field
experiment in 2002. Developed and implemented the Noah and Noah-MP land
surface and hydrology models for MM5 and WRF. Led an international
effort to develop the integrated WRF-Urban modeling system.
