NOAA National Blend of Models (NBM)

The National Blend of Models (NBM) is a nationally consistent and skillful suite of calibrated forecast guidance based on a blend of both NWS and non-NWS numerical weather prediction model data and post-processed model guidance. The goal of the NBM is to create a highly accurate, skillful and consistent starting point for the gridded forecast.国家混合模型（NBM）是一套全国范围内一致且技艺精湛的校准预测指南，该指南基于国家气象服务（NWS）及非NWS数值天气预报模型数据的混合以及后处理模型指南。NBM的宗旨在于构建一个高度精确、技艺高超且一致的网格化预报起点。
