stormwindmodel (version 0.1.4)

summarize_grid_wind: Generate wind summaries for grid point

Description

Summarizes the wind time series for a single grid point, as created by calc_grid_wind.

Usage

summarize_grid_wind(
  grid_wind,
  tint = 0.25,
  gust_duration_cut = 20,
  sust_duration_cut = 20
)

Arguments

grid_wind

A dataframe with a time series of modeled wind speeds at a location, as created by calc_grid_wind.

tint

Interval (in hours) to which to interpolate the tracks. The default is 0.25 (i.e., 15 minutes).

gust_duration_cut

The wind speed, in meters per second, to use as a cutoff point for determining the duration of gust winds. The function will calculate the minutes during the storm when surface-level gust winds were above this speed at the location.

sust_duration_cut

The wind speed, in meters per second, to use as a cutoff point for determining the duration of gust winds. The function will calculate the minutes during the storm when surface-level gust winds were above this speed at the location.

Value

Returns a one-row matrix with wind characteristics for a single location. The wind characteristics given are:

• vmax_gust: Maximum value of surface-level (10 meters) gust winds, in meters per second, over the length of the storm at the given location

• vmax_sust: Maximum value of surface-level (10 meters) sustained winds, in meters per second, over the length of the storm at the given location

• gust_duration: Length of time, in minutes, that surface-level gust winds were above a specified value (default is 20 meters per second)

• sust_duration: Length of time, in minutes, that surface-level sustained winds were above a specified value (default is 20 meters per second
