HURDAT dataset for the Atlantic basin.
1 |
A dataframe with 21 variables.
Key
Unique key identifying the tropical cyclone. Formatted like AABBCCCC where AA is Basin, BB is YearNum and CC is Year
Name
Name of the storm (UNNAMED for early storms)
DateTime
Date and time of observation in UTC, POSIXct
Record
Record identifier:
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 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.
W
Maximum sustained wind speed.
Status
Status of the system:
TD
Tropical depression (winds < 34 kts)
TS
Tropical storm (winds 34-63 kts)
HU
Hurricane (winds >= 64 kts)
EX
Extratropical cyclone of any intensity
SD
Subtropical cyclone of subtropical depression intensity (winds < 34 kts).
SS
Subtropical cyclone of subtropical cyclone intensity (winds >= 34 kts)
LO
A low that is neither a tropical cyclone, subtropical cyclone nor extratropical of any intensity.
WV
Tropical wave
DB
Tropical disturbance
Lat
