Deduplicate synthetic storm tracks using
track_id
and
timestep
Deduplicate storm tracks
prior
to labelling with
DatetimeIndex
Check storm tracks have consecutive and monotonically increasing timestep
Increase country-storm search buffer from 2 to 3 degrees
Filter storm tracks so we keep track sections from 'first arrival to last departure' rather than simply those intersecting a buffer
Limit interpolation to 6 hours between track timesteps. Otherwise return zero wind speeds for timestep.
Check wind field estimation parameters are physical
Refactor wind estimation so advective and rotational components are calculated more closely in code (eases re-use of evaluation grid)
Taper advective winds as function of absolute distance from storm eye -- advective field decays to nothing at radius 1,000km.
