Title

  • Development of the Regional Climate-Weather Research and Forecasting (CWRF) model: surface boundary conditions.

Description

  • The Climate-Weather Research and Forecasting (CWRF) is the climate extension of the Weather Research and Forecasting (WRF) model, incorporating all WRF functionalities for numerical weather predictions while enhancing the capability for climate applications. This report focuses on the construction and implementation of surface boundary conditions (SBCs) specifically designed for CWRF mesoscale modeling applications. The primary SBCs include surface topography (mean elevation, slope, curvature, and their standard deviations); bedrock, lakebed, or seafloor depth; soil sand, and clay fraction profiles; surface albedo localization factor; bottom soil temperature; surface characteristic identification; land cover category; fractional vegetation cover; leaf and stem area index; sea surface temperature, salinity, and current; and sea temperature and salinity profiles. They are currently presented in a CWRF domain suitable for the U.S applications at 30-kilometer spacing. The raw data sources and processing procedures, however, are elaborated in detail, by which the SBCs can be readily constructed for any specific CWRF domain anywhere in the world. For a specific field, alternative data sources, if available, were compared to quantify uncertainties and suggest the choice or improvement.
