tc.pdi.all: Hurricane Observations from the NATL and EPAC basins
In aldomann/hurdat-hadisst-data: Hurricane and SST Unified Data Sets

A dataset containing summarised hurricane/tropical-cyclone observations from the North Atlantic (1966-2016) and Northeast Pacific (1986-2016) basins.

1	data(tc.pdi.all)

A data frame with 1365 rows and 13 variables

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) or EPAC (Northeast Pacific).
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.
