Description
This R package currently aims to reorganize the NOAA HURDAT2
dataset for Atlantic, East Pacific and Central Pacific-basin tropical
cyclones and present it in a cleaner format.
Details
The Atlantic basin dataset covers all cyclones that have developed in the
Atlantic Ocean. The eastern Pacific datasets cover cyclones in the Pacific
from the United States/Mexico coastlines to -140°W where the cyclone
entered what is referred to as the central Pacific basin. The central
Pacific basin extends westward to -180°W.
Named Cyclones
Cyclones were not named until 1950 and used names of the international
phonetic alphabet. For example, Able, Baker, Charlie, etc.
In 1953, the National Hurricane Center began
using female names and by 1954 the NHC would retire some names for storms of
significance. Currently the
World
Meteorological Organization
is responsible for maintaining the list of names, retiring names and
assigning replacement names.
In this dataset, cyclones not named are simply referred to as "UNNAMED". To
aid with identification, cyclones will be referenced by their 'Key', a
string of alphanumeric characters identifying basin, the number of the storm
for the year, followed by the four-digit year.
For example, *AL011851*:
AL = Atlantic Basin ('Basin')
01 = First storm of the year ('YearNum')
1851 = Year of the storm ('Year')
Meteorological Definitions
It is useful to understand definitions and classifications of tropical
cyclones.
Cyclone: a system of winds rotating inward to an area of low
pressure. This system rotates counter-clockwise in the northern
hemisphere and clockwise in the southern hemisphere.
Tropical depression: a tropical cyclone with winds less than 35 mph
(34 kts).
Tropical storm: a tropical with winds between 35 mph (34 kts) but
less than 74mph (64 kts).
Hurricane: a tropical cyclone with winds greater than 74 mph
(64 kts).
Extratropical Cyclone: a cyclone no longer containing tropical
characteristics (warm-core center, tight pressure gradient near the
center)
Subtropical Cyclone: a cyclone containing a mix of tropical and
non-tropical characteristics.
Tropical cyclone: a warm-core surface low pressure system
Tropical Wave: An open area of low pressure (trough) containing
tropical characteristics
Disturbance: An area of disturbed weather; a large disorganized area
of thunderstorms.
Error Reporting
Please submit any errors, discrepancies or issues through the
timtrice/HURDAT repository.
Errors in the raw data may also be reported to Chris Landsea or the National
Hurricane Center Best Track Change Committee
as
explained on the HRD website.
