. (2011) studied PMP for a catchment in California and applied a regional-scale high-resolution physical atmospheric model. Other studies have also applied NWP-based methods to estimate PMP, where the approach is based on physical maximization of a historical extreme rainstorm. Ishida et al. (2015a) alters boundary and initial conditions to maximize precipitation over targeted catchments. Chen and Hossain (2018) pointed out that there seems to have emerged a consensus that using a physical

nature of floods in the current climate, it is necessary to understand how they may change in a future warmer climate. Future flood risk has been examined globally and in the CONUS using flood inundation models and flood exposure estimates under various population growth scenarios ( Hirabayashi et al. 2013 ; Wing et al. 2018 ). While these studies highlight an increased future flood risk, future flood estimates are uncertain due to 1) the underestimation of rainfall in global climate models (GCMs

Tapiador et al. 2017 ). When used as input for subsequent modeling (e.g., hydrology, land surface data assimilation), the uncertainties of the precipitation need to be estimated ( Pappenberger and Beven 2006 ). The current study focuses on uncertainties of gridded precipitation analysis (PA) by using ensembles. Recent research on ensemble meteorological fields ( Buizza 2019 ; Duan et al. 2019 ; Raut et al. 2018 , among others) has revealed an increasing interest in the uncertainty assessment and an

found that floods and debris flow were associated with ARs during the cool season in Northern California and flash floods not associated with ARs during the warm season in Southern California. Along the West Coast, the top 11 out of 20 counties with the highest proportion of flood damage due to ARs are located in California ( Corringham et al. 2019 ). Given the impact ARs have on California’s precipitation, floods, and water resources, current research has investigated how ARs might change in a

1. Introduction High-resolution and high-accuracy quantitative precipitation estimation (QPE) is a key component for many applications in agriculture, manufacturing, flash flood detection, river flood prediction, water resource managements, and climate assessments. The observation of precipitation requires various remote sensing systems and networks encompassing surface rain/snow gauges, radar, and satellite. Among them, ground radar networks currently provide the highest spatial and temporal

Wang et al. (2019) . In this paper, we describe the implementation of R ( A ) within our current real-time QPE framework based on R ( Z ) and comparatively assess the performance of the adapted R ( A ) and current R ( Z ) algorithms. In section 2 , we provide information on the spatial domain and data for WSR-88D radars, temperature sounding retrieved from the numerical weather prediction model analysis, and ground reference data used in this study. Section 3 describes our R ( A

authors commented that further work was needed to assess sensitivity to sub-plateau-scale surface wetness patterns. The impact of soil moisture (SM) on moist convection has been recognized by numerous works (e.g., see reviews by Seneviratne et al. 2010 ; Santanello et al. 2018 ). SM affects the partitioning of surface fluxes into sensible and latent heat, which control planetary boundary layer (PBL) growth and moisture availability, respectively. Depending on the atmospheric stability profile

hand, the LULC gives information about the land’s physical type and how it is currently being used (i.e., urban, cropland, shrubland, desert, etc.), determining surface properties such as albedo, emissivity and roughness length. While the albedo and emissivity are normally estimated using remote sensing assets such as satellites (e.g., Giri 2012 ; Sun and Schulz 2015 ; Fritz et al. 2017 ; Rwanga and Ndambuki 2017 ), and sometimes through field surveys (e.g., D’Antona et al. 2008 ), the

of convective parameterizations has been obtained for resolutions higher than 4 km (e.g., Kain et al. 2008 ; Weisman et al. 2008 ). This model configuration, as well as the initial and lateral boundary conditions (IC/LBCs) are taken from one ensemble member out of all the ensemble strategies investigated in Part II. In particular, the boundary conditions are extracted from the global ECMWF ensemble prediction system and soil parameters are downscaled from the control member of the ECMWF

with previous research using WRF at this horizontal grid spacing for this application (e.g., Shi and Xue 2019 ; Wright et al. 2013 ). Hourly updated Rapid Refresh ( Benjamin et al. 2016a ) fields were used as initial and lateral boundary conditions as currently applied in operations. A one-dimensional lake model implemented in WRF ( Oleson et al. 2013 ) was used for smaller inland lakes. Over the Great Lakes, the control lower boundary condition for the lake surface (i.e., lake
