摘要边界层、地表和次表层是水文系统的重要协同演化组成部分。虽然以前的研究已经研究了土壤水分、地下水和大气之间的关系，但大气对区域地下水位下降的响应却没有受到太多关注。为了解决这个问题，采用了一个水文-大气耦合模型[平行流水文模型(ParFlow)和WRF]来模拟加利福尼亚州中部的圣华金河流域。这项研究特别关注模拟中的行星边界层(PBL)，模拟了两种地下水位配置：模拟自然条件的高地下水位和反映加州中央山谷地下水开采历史的低地下水位，尽管没有模拟灌溉的影响。对地下水位条件进行了包括三种边界层方案和六种初始条件的一整套模拟，以评估概念性条件和初始条件的不确定性。
AbstractThe boundary layer, land surface, and subsurface are important coevolving components of hydrologic systems. While previous studies have examined the connections between soil moisture, groundwater, and the atmosphere, the atmospheric response to regional water-table drawdown has received less attention. To address this question, a coupled hydrologic–atmospheric model [Parallel Flow hydrologic model (ParFlow) and WRF] was used to simulate the San Joaquin River watershed of central California. This study focuses specifically on the planetary boundary layer (PBL) in simulations with two imposed water-table configurations: a high water table mimicking natural conditions and a lowered water table reflecting historic groundwater extraction in California’s Central Valley, although effect of irrigation was not simulated. An ensemble of simulations including three boundary layer schemes and six initial conditions was performed for both water-table conditions to assess conceptual and initial condition uncert...
