summarize_grid_winds | R Documentation |
Summarizes the wind time series for grid points, as
created by calc_grid_winds
.
summarize_grid_winds( grid_winds, gust_duration_cut = 20, sust_duration_cut = 20, tint = 0.25 )
grid_winds |
A matrix where each column is a time series of modeled wind speeds at
a location, as created by |
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. |
tint |
Interval (in hours) to which to interpolate the tracks. The default is 0.25 (i.e., 15 minutes). |
Returns a dataframe with wind characteristics for each 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
