@ChrisFairless proposed to read the storm type data from IBTrACS data in PR #646:

Changes proposed in this PR:

• When creating a trackset from IBTrACS also read the 'Nature' of a storm. The nature gives information about whether a system is a disturbance, tropical storm, post-transition extratropical storm, or subtropical storm (or whether agencies disagree or don't report). This is potentially useful in visualisations and for generating synthetic tracks.

@tovogt #646 (comment):

I tend to prefer supporting a keyword argument for "other variables" to include instead of adding explicit support for the "nature" variable. Maybe we can start by supporting non-agency-specific variables, because the agency-specific need to be treated a bit differently?
