The Hurricane Research Division (HRD) conducts research using a combination of models, theories, and observations, with particular emphasis on data obtained with research aircraft. The goal of this research is to improve the prediction of 1- to 7-day forecasts of tropical cyclone track, intensity, structure, and precipitation, and their impacts. HRD is interested in research that specifically addresses this goal during the tropical cyclone lifecycle from genesis to decay or extratropical transition in any of the following areas:
(1) Air-sea interaction processes—research of thermodynamic processes in the atmospheric boundary layer and the adjacent upper ocean that impact tropical cyclone structure and/or the intensity change.
(2) Numerical weather prediction—advancement of numerical models for tropical cyclones focusing on model dynamics and physical processes in high-resolution HWRF.
(3) Vortex- and convective-scale processes and interactions—increase in the understanding of the role of symmetric/asymmetric vortex dynamics and convective-scale processes in TC structure and intensity change.
(4) Turbulence processes—analysis of in situ and remote-sensing aircraft observations throughout the atmosphere to quantify turbulent fluxes, turbulent intensity, and mixing length for improved representation and parameterization of tropical cyclone models.
(5) Boundary-layer processes—accurate characterization of the mean structure and small-scale turbulent processes in the atmospheric boundary layer and quantitative assessment of their impact on tropical cyclone energetics and intensity change.
(6) Data assimilation—research on data assimilation methods, algorithm improvement, optimal utilization of observations, new observational platforms, representation of model error, and parameter estimation, relevant to tropical cyclones and their environments, with emphasis on both aircraft and satellite data.
