sounding_barbs {thunder}

Plot wind profile using wind barbs

Description

Function for plotting wind direction and wind speed profile with the use of wind barbs. Can be launched as standalone function or coupled with pre-drawn Skew-T diagram.

Usage

sounding_barbs(
  pressure,
  ws,
  wd,
  altitude,
  ptop = 100,
  interpolate = TRUE,
  showaxis = FALSE,
  barb_cex = 0.3,
  ...
)

Arguments

pressure

pressure [hPa]

ws

wind speed [knots]

wd

wind direction [azimuth in degrees]

altitude

altitude [m] (can be above sea level or above ground level as function always consider first level as surface, i.e h = 0 m) - altitude [m]

ptop

Pressure top level [hPa] to be used for plotting wind speed. Valid options should be < 200 hPa (100 by default)

interpolate

logical, draw wind barbs only at interpolated altitudes with 500 m interval (default = TRUE) instead of all wind barbs for a given input dataset

showaxis

logical, drawing bounding box with left axis for pressure heighs (default FALSE)

barb_cex

size of wind barbs (default = 0.3)

...

extra graphic arguments

Value

wind barbs plot for a given vertical profile of atmosphere

Examples

# load examplary dataset:
data("sounding_vienna")
attach(sounding_vienna)
sounding_barbs(pressure = pressure, ws = ws, wd = wd, altitude = altitude,
              interpolate = TRUE, showaxis = TRUE)
