Increasing vertical resolution in US models to improve track forecasts of Hurricane Joaquin with HWRF as an example. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance For forecasts of Hurricane Joaquin in 2015, the European Centre for Medium-Range Weather Forecasting model consistently and correctly predicted a track away from the US mainland, while the National Oceanic and Atmospheric Administration National Centers for Environmental Prediction Global Forecast System (GFS) and ...

Tropical Cyclone Winds from WindSat, AMSR2, and SMAP: Comparison with the HWRF Model [PDF]
Remote Sensing, 2021 A new data set of tropical cyclone winds (‘TC-winds’) through rain as observed by the WindSat and AMSR2 microwave radiometers has been developed by making use of a linear combination of C- and X-band frequency channels.

A comparison of HWRF, ARW and NMM models in Hurricane Katrina (2005) simulation. [PDF]
Int J Environ Res Public Health, 2011 The life cycle of Hurricane Katrina (2005) was simulated using three different modeling systems of Weather Research and Forecasting (WRF) mesoscale model. These are, HWRF (Hurricane WRF) designed specifically for hurricane studies and WRF model with two different dynamic cores as the Advanced Research WRF (ARW) model and the Non-hydrostatic Mesoscale ...

Evaluation of Hurricane Harvey (2017) Rainfall in Deterministic and Probabilistic HWRF Forecasts
Atmosphere, 2020 Rainfall forecast performance was evaluated for the first time for the Hurricane Weather Research and Forecasting (HWRF) model. This study focused on HWRF performance in predicting rainfall from Hurricane Harvey in 2017. In particular, two configurations

A Comparative Modeling Study of Supertyphoons Mangkhut and Yutu (2018) Past the Philippines with Ocean-Coupled HWRF [PDF]
Atmosphere, 2021 The ocean-coupled Hurricane Weather Research and Forecasting (HWRF) system was used to investigate the evolution of Supertyphoons Mangkhut and Yutu (2018) over the Philippines Sea and near landfall in the northern Philippines. The simulation results indicate that Mangkhut at a deepening stage has a smaller track sensitivity to the use of different ...

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 ...

Performance of Ocean Simulations in the Coupled HWRF–HYCOM Model
Journal of Atmospheric and Oceanic Technology, 2014 Abstract This paper introduces a next-generation operational Hurricane Weather Research and Forecasting (HWRF) system that was developed at the U.S. National Centers for Environmental Prediction. The new system, HWRF–Hybrid Coordinate Ocean Model (HYCOM), retains the same atmospheric component of operational HWRF, but it replaces the ...
