Windrose (speed/direction) diagram of a station over a time period

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

Usage

windrose_period(
  station,
  start = 2000,
  end = 2010,
  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().

start

Numeric value with the start year (format: YYYY).

end

Numeric value with the end year (format: YYYY).

n_directions

Numeric value with the number of direction bins to plot (petals on the rose). Valid values are 4, 8 or 16.

n_speeds

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

speed_cuts

Numeric vector with 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

Numeric value with the upper limit for wind speed that is considered calm (default 0).

legend_title

Character string to be used for the legend title.

verbose

Logical. If TRUE, provides information about the flow of information between the client and server.

Value

A ggplot2 object. See help("ggplot2").

API key

You need to set your API key globally using aemet_api_key(). Query timeout can be controlled with options(climaemet_timeout = 60) (default value). See httr2::req_timeout() for details.
