wind_var
parameter. If the Extended Best
Tracks wind radii are used as the source of the wind data, the sustained
winds will only be available for cutpoints of 34 knots, 50 knots, and 64
knots, so these values should be used (e.g., to get all counties with winds of
34 knots or higher, you could use wind_limit = 17.4
, with the limit
given as a value just below 34 knots in the units meters per second)."vmax_sust"
(maximum sustained winds; default), "vmax_gust"
(maximum gust winds), "sust_dur"
(minutes of sustained winds of 20 m / s
or higher) and "gust_dur"
(minutes of gust winds of 20 m / s or higher).
If the Extended Best Tracks wind radii are used as the source of wind data,
the "gust_dur"
option cannot be selected."modeled"
, for estimates based on running a wind model from Best
Tracks data inputs, and "ext_tracks"
, for estimates based on
the wind radii in the Extended Best Tracks data. See the help files for the
datasets storm_winds
and ext_tracks_wind
in the
hurricaneexposuredata
package for more details on each of these sources
for wind estimates. For the gust wind estimates, these are based on applying
a gust factor of 1.49 to the sustained wind estimates in both wind data sources.storm_id
: Unique storm identifier with the storm name and year,
separated by a hyphen(e.g., "Alberto-1988",
"Katrina-2005")
fips
: County's 5-digit Federal Information Processing Standard
(FIPS) code
max_sust
: Maximum sustained wind speed (in m / s)
max_gust
: Maximum gust wind speed (in m / s)
sust_dur
: Minutes sustained wind speed was 20 m / s or higher
gust_dur
: Minutes gust wind speed was 20 m / s or higher (only
returned if the modeled winds are requested using wind_source
)
