Assessment of Saildrone Extreme Wind Measurements in Hurricane Sam Using MW Satellite Sensors

Remote Sensing, 2022
In 2021, a novel NOAA-Saildrone project deployed five uncrewed surface vehicle Saildrones (SDs) to monitor regions of the Atlantic Ocean and Caribbean Sea frequented by tropical cyclones.

Sensitivity of an Idealized Tropical Cyclone to the Configuration of the Global Forecast System–Eddy Diffusivity Mass Flux Planetary Boundary Layer Scheme

Atmosphere, 2021
The intensity and structure of simulated tropical cyclones (TCs) are known to be sensitive to the planetary boundary layer (PBL) parameterization in numerical weather prediction models.

Comparative performance of HWRF model coupled with POM and HYCOM for tropical cyclones over North Indian Ocean

MAUSAM, 2021
The demonstration of air-sea interaction in the high-resolution numerical weather prediction (NWP) model is the necessary condition to predict the extreme event like tropical cyclone. It is already established that the coupled mesoscale models are capable of forecasting the track and intensity of tropical cyclones with reasonable skill over North ...

Sensitivity of the Wave Field to High Time-Space Resolution Winds during a Tropical Cyclone

Oceans, 2023
The impact of the high space-temporal variability of the wind field during the moderate and intense storm stages of a tropical cyclone on the wave field as computed by the numerical model WaveWatch III is investigated in this work.

Role of eyewall and rainband eddy forcing in tropical cyclone intensification [PDF]

Atmospheric Chemistry and Physics, 2019
While turbulence is commonly regarded as a flow feature pertaining to the planetary boundary layer (PBL), intense turbulent mixing generated by cloud processes also exists above the PBL in the eyewall and rainbands of a tropical cyclone (TC).

Relative Accuracy of HWRF Reanalysis and a Parametric Wind Model during the Landfall of Hurricane Florence and the Impacts on Storm Surge Simulations

Natural Hazards, 2022
Abstract Prediction and reanalysis of storm surge rely on wind and pressure fields from either parametric tropical cyclone wind models or numerical weather model reanalysis, and both are subject to large errors during landfall. This study assesses two sets of wind/pressure fields for Hurricane Florence that made landfall along the Carolinas in ...

Understanding the Role of Mean and Eddy Momentum Transport in the Rapid Intensification of Hurricane Irma (2017) and Hurricane Michael (2018)

Atmosphere, 2021
The prediction of rapid intensification (RI) in tropical cyclones (TCs) is a challenging problem. In this study, the RI process and factors contributing to it are compared for two TCs: an axis-symmetric case (Hurricane Irma, 2017) and an asymmetric case (
