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.
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
