clouddrift.adapters.hurdat2

This module defines functions used to adapt the HURDAT2 cyclone track data as a ragged-array dataset.

Functions

to_raggedarray([basin, tmp_path, convert])

Classes

DataLine(time, record_identifier, ...)
HeaderLine(id, basin, year, rowsize)
RecordIdentifier(value[, names, module, ...])	C – Closest approach to a coast, not followed by a landfall G – Genesis I – An intensity peak in terms of both pressure and wind L – Landfall (center of system crossing a coastline) P – Minimum in central pressure R – Provides additional detail on the intensity of the cyclone when rapid changes are underway S – Change of status of the system T – Provides additional detail on the track (position) of the cyclone W – Maximum sustained wind speed
SystemStatus(value[, names, module, ...])	TD – Tropical cyclone of tropical depression intensity (< 34 knots) TS – Tropical cyclone of tropical storm intensity (34-63 knots) HU – Tropical cyclone of hurricane intensity (> 64 knots) EX – Extratropical cyclone (of any intensity) SD – Subtropical cyclone of subtropical depression intensity (< 34 knots) SS – Subtropical cyclone of subtropical storm intensity (> 34 knots) LO – A low that is neither a tropical cyclone, a subtropical cyclone, nor an extratropical cyclone (of any intensity) WV – Tropical Wave (of any intensity) DB – Disturbance (of any intensity) ET - UNKNOWN found in Northeast Pacific Basin PT - UNKNOWN found in Northeast Pacific Basin ST - UNKNOWN found in Northeast Pacific Basin TY - UNKNOWN found in Northeast Pacific Basin
