AL: Atlantic HURDAT

In timtrice/HURDAT: Hurricane Re-Analysis Project

Description

HURDAT dataset for the Atlantic basin.

Usage

AL

Format

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)
