  1. North American Regional Climate Simulations with WRF/Noah-MP: Validation and the effect of groundwater interaction Michael Barlage MukulTewari, Fei Chen, Kevin Manning (NCAR) Gonzalo Miguez-Macho (U. Santiago) 14th WRF Users’ Workshop, 26 June 2013

  2. Domain and Setup • Two six-month 30km simulations starting Feb 25 • 2002 and 2010 • Spin-up soil for one year using offline HRLDAS • IC/BC from NARR • CAM radiation; YSU; Thompson

  3. LSM Setup • Default Noah LSM • Noah-MP with OPT_RUN=3: free drainage comparable to Noah runoff scheme • Noah-MP with OPT_RUN=5: Miguez-Macho & Fan groundwater with equilibrium water table • Noah-MP with OPT_BTR=1(Noah) and 2 (CLM)

  40. Summary • Tested a new groundwater option to Noah-MP that accounts for aquifer interaction • Noah-MP performs better than Noah for near surface temperature (with exceptions), though more optimization is likely required • Noah-MP performs the same (2002) or regionally worse (2010) for precipitation • In regions with low water table depth, upward transport of water: • Increases late summer latent heat flux • Has little effect on precipitation • Improves surface temperature simulation
