Description

Hurricane best track database (HURDAT2).

Atlantic basin 1851-2018.

Table Schema

Table Schema

Name Type Min Max Description
seq DOUBLE 1* 31*

ATCF cyclone number for that year

name STRING

Hurricane name. e.g. "ALEX"

datetime STRING

Observation time in UTC. Format is YYYY-MM-DDTHH:MM:SS.

record_id STRING

Single letter desinating a specific event in a hurricane track. An empty string if no code.

  • 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
status STRING

Status of system:

  • DB – Disturbance (of any intensity)
  • ET - Unknown. The only occurrence is in HARVEY.
  • EX – Extratropical cyclone (of any intensity)
  • HU – Tropical cyclone of hurricane intensity (> 64 knots)
  • LO – A low that is neither a tropical cyclone, a subtropical cyclone, nor an extratropical cyclone (of any intensity)
  • SD – Subtropical cyclone of subtropical depression intensity (< 34 knots)
  • SS – Subtropical cyclone of subtropical storm intensity (> 34 knots)
  • TD – Tropical cyclone of tropical depression intensity (< 34 knots)
  • TS – Tropical cyclone of tropical storm intensity (34-63 knots)
  • WV – Tropical Wave (of any intensity)
