The EMC Verification System (EVS) is a new application designed to provide real-time model verification analysis in a single, unified software system and uses the Model Evaluation Tools (METplus) developed by the Developmental Testbed Center (DTC). EVS will perform model verification on Unified Forecast System (UFS) environmental prediction models. One such component of the EVS, EVS-TC (EVS-Tropical Cyclone), currently verifies the following metrics for EMC’s hurricane modeling systems: intensity bias and absolute error; along and cross track biases, and absolute track errors; radius of maximum wind errors; rapid intensification/weakening performance; and maximum extent of winds. This study will examine the results from the 2023 tropical cyclone seasons with the first operational season of the Hurricane and Analysis Forecast System (HAFS), and the final season of the Hurricane Weather Research and Forecast System (HWRF) and Hurricanes in a Multi-scale Ocean coupled Non-hydrostatic Model (HMON) models.
