Storm tracks data

Description

This dataset is the NOAA Atlantic hurricane database best track data, https://www.nhc.noaa.gov/data/#hurdat. The data includes the positions and attributes of storms from 1975-2022. Storms from 1979 onward are measured every six hours during the lifetime of the storm. Storms in earlier years have some missing data.

Usage

storms

Format

A tibble with 19,537 observations and 13 variables:

name

year,month,day

Date of report

hour

Hour of report (in UTC)

lat,long

Location of storm center

status

Storm classification (Tropical Depression, Tropical Storm, or Hurricane)

category

• 4: 113+ knots

• 5: 137+ knots

wind

storm's maximum sustained wind speed (in knots)

pressure

Air pressure at the storm's center (in millibars)

tropicalstorm_force_diameter
