2020 HFIP R&D Activities Summary: Recent Results and Operational Implementation

This technical report describes the activities and results of the Hurricane Forecast Improvement Program (HFIP) that occurred in 2020. The major development focus remained in building the next generation hurricane model, the Hurricane Analysis and Forecast System (HAFS) within the Unified Forecast System (UFS), primarily for track and intensity predictions. This report summarizes the progress made in 2020, including model developments and the second year of progress made towards transitioning the next generation hurricane modeling system, HAFS, into operations.

本技术报告详述了2020年度飓风预报改进计划（Hurricane Forecast Improvement Program, HFIP）的相关工作与取得的成果。该计划的核心研发方向始终聚焦于在统一预报系统（Unified Forecast System, UFS）框架内构建下一代飓风预报模型——飓风分析与预报系统（Hurricane Analysis and Forecast System, HAFS），主要用于热带气旋路径与强度预报。本报告梳理了2020年取得的各项进展，涵盖模型研发工作，以及下一代飓风建模系统HAFS向业务化转型进程中的第二年度成果。
