Plot a windrose showing the wind speed and direction for a station over a days period.

Usage

windrose_days(
  station,
  start = "2000-12-01",
  end = "2000-12-31",
  n_directions = 8,
  n_speeds = 5,
  speed_cuts = NA,
  col_pal = "GnBu",
  calm_wind = 0,
  legend_title = "Wind Speed (m/s)",
  verbose = FALSE
)

Arguments

station

Character string with station identifier code(s) (see aemet_stations()) or "all" for all the stations.

start

Character string as start date (format: "YYYY-MM-DD").

end

n_directions

Numeric value as the number of direction bins to plot (petals on the rose). The number of directions defaults to 8.

n_speeds

Numeric value as the number of equally spaced wind speed bins to plot. This is used if speed_cuts is NA (default 5).

speed_cuts

Numeric vector containing the cut points for the wind speed intervals, or NA (default).

col_pal

Character string indicating the name of the hcl.pals() color palette to be used for plotting.

calm_wind
