"Tropical cyclones tracks are gathered in the class `TCTracks` and then provided to the hazard `TropCyclone` which computes the wind gusts at each centroid. `TropCyclone` inherits from `Hazard` and has an associated hazard type `TC`."

"\n",
"`TCTracks` reads and handles historical tropical cyclone tracks of the [IBTrACS](https://www.ncdc.noaa.gov/ibtracs/) repository or synthetic tropical cyclone tracks simulated using fully statistical or coupled statistical-dynamical modeling approaches. It also generates synthetic tracks from the historical ones using Wiener processes.\n",
"\n",
"The tracks are stored in the attribute `data`, which is a list of `xarray`'s `Dataset` (see [xarray.Dataset](http://xarray.pydata.org/en/stable/generated/xarray.Dataset.html)). Each `Dataset` contains the following variables:\n",
