In this study is evaluated the feasibility of applying a vortex relocation scheme based on a synthetic vortex in the Numerical Tools for Hurricane Forecast (NTHF) system. For this, the hurricanes Dorian and Lorenzo, as well as the tropical storm Karen were selected as case studies. In the experiments carried out, it was found that the vortex relocation scheme represents a more structured tropical cyclone (TCs), although the dynamic instability caused by the introduction of the synthetic vortex in the background eld conditioned that the center of the TCs developed in a drier environment and the center of the system were colder, which led to an increase of the mean errors in the track and intensity forecast, with respect to the experiments without vortex relocation.
