tc.pdi.geog.natl: Hurricane Observations from the NATL basin with Geographical...

In aldomann/hurdat-hadisst-data: Hurricane and SST Unified Data Sets

Description

A dataset containing summarised hurricane/tropical-cyclone observations from the North Atlantic (1966-2016) basin with additional geographic variables.

Usage

data(tc.pdi.geog.natl)

Format

A data frame with 771 rows and 18 variables

Details

The variables are as follows:

• storm.id: Unique storm ID. Constructed by basin (chars. 1-2) + ATCF cyclone number for that year (chars. 3-4) + Year (chars. 5-8).

• storm.name: Name, if available, or else "UNNAMED".

• n.obs: Number of best track entries.

• storm.duration: Lifetime of the storm in seconds.

• storm.pdi: Power-dissipation index. An indicator of the released energy of a hurricane, it integrates (cubic) wind speed over tropical-cyclone lifetime.

• max.wind: supremum of the maximum sustained surface wind speed.

• mean.wind: mean of the maximum sustained surface wind speed.

• mean.sq.wind: mean of the squared maximum sustained surface wind speed.

• storm.year: Year of storm occurrence.

• basin: NATL (North Atlantic), this column is kept for structure consistency.

• sst: Annual and basin-wide averaged sea surface temperature.

• sst.norm: Normalised SST.

• sst.class: low for sst.norm < 1, high for sst.norm >= 1.

• first.lat: Genesis latitude of the storm.

• last.lat: Death latitude of the storm.

• first.long: Genesis longitude of the storm.

• last.long: Death latitude of the storm.

• distance: Path length of the storm. Calculated using the Spherical Law of Cosines.

The hurricane data (variables 1-9, 14-18) comes from the HURDAT2, while the SST is calculated from the HadISST1 (variables 11-13).
