Performance of Basin-Scale HWRF Tropical Cyclone Track Forecasts

Weather and Forecasting, 2017
Abstract The Hurricane Weather Research and Forecasting (HWRF) Model is a dynamical model that has shown annual improvements in its tropical cyclone (TC) track forecasts as a result of various modifications. This study focuses on an experimental version of HWRF, called the basin-scale HWRF (HWRF-B), configured with 1) a large, static ...

On the growth of intensity forecast errors in the operational hurricane weather research and forecasting (HWRF) model

Quarterly Journal of the Royal Meteorological Society, 2018
This study examines the growth of tropical cyclone (TC) intensity forecast errors and related intensity predictability for the NOAA operational Hurricane Weather Research and Forecasting (HWRF) model. Using operational intensity forecasts during the 2012 to 2016 seasons, two conditions for a limited range of TC intensity predictability are demonstrated,

Simulation of very severe cyclone Mala over Bay of Bengal with HWRF modeling system

Natural Hazards, 2011
Tropical cyclone is one of the most devastating weather phenomena all over the world. The Environmental Modeling Center (EMC) of the National Center for Environmental Prediction (NCEP) has developed a sophisticated mesoscale model known as Hurricane Weather Research and Forecasting (HWRF) system for tropical cyclone studies.

Vertical structure of tropical cyclones at onset of the rapid intensification in the HWRF model

Geophysical Research Letters, 2014
In this study, the tropical cyclone structure at the onset of rapid intensification (RI) is examined using the cloud-permitting version of the Hurricane Weather Research and Forecast (HWRF) model. Idealized experiments with different vortex initial vertical structures in different environments show that the HWRF model vortex possesses a specific ...

Validation of the HWRF-POM and HWRF-HYCOM hurricane forecasting systems during Hurricane Dorian using glider observations

Global Oceans 2020: Singapore – U.S. Gulf Coast, 2020
Hurricane Dorian devastated the Bahamas in August 2019 when it underwent rapid intensification and transitioned from a category 4 to a category 5 storm. The operational hurricane forecasting models consistently under predicted the intensity evolution of Dorian.

Validation of HWRF-based Probabilistic TC Wind and Precipitation forecasts

Weather and Forecasting, 2021
AbstractTropical cyclones are associated with a variety of significant social hazards, including wind, rain, and storm surge. Despite this, most of the model validation effort has been directed toward track and intensity forecasts. In contrast, few studies have investigated the skill of state-of-the-art, high-resolution ensemble prediction systems in ...

Performance of the experimental HWRF in the 2008 Hurricane Season

Natural Hazards, 2011
In response to the needs of improving hurricane forecasts, we have built an experimental version of the operational Hurricane Weather Research and Forecasting Model (HWRF), which is based on the Weather Research and Forecasting Nonhydrostatic Mesoscale Model of the National Oceanic and Atmospheric Administration (NOAA). The experimental HWRF (HWRFx) is

Performance of the HWRF Rapid Intensification Analog Ensemble (HWRF RI-AnEn) during the 2017 and 2018 HFIP Real-Time Demonstrations

Weather and Forecasting, 2020
AbstractThe performance of the Hurricane Weather Research and Forecasting (HWRF) Model Rapid Intensification Analog Ensemble (RI-AnEn) is evaluated for real-time forecasts made during the National Oceanic and Atmospheric Administration (NOAA)’s 2018 Hurricane Forecast Improvement Program (HFIP) demonstration.
