plotWind: Winds Profile Plot

In RadioSonde: Tools for Plotting Skew-T Diagrams and Wind Profiles

Winds Profile Plot

Description

Creates a wind profile in the standard atmospheric notation. Each full barb = 10 m/s, half barb = 5 m/s, and a filled triangle for 50 m/s. The maximum wind speed that can be plotted without amending the program is 65 m/s.

Usage

plotWind(sondeData, sizeBarb = NULL, ylim = c(1050, 100),
         thin=NULL, legend = FALSE, lwd=1, col="green4",
         axis=TRUE)
	 

Arguments

sondeData	Data frame for sounding data, must have components for wind speed wspd, wind direction dir, and pressure press.
sizeBarb	change the thickness of the plotted lines
thin	Max number of wind barbs to draw.
axis	If TRUE add an axis in pressure.
col	Color of barbs
lwd	Line width for barbs
ylim	Plot extent, in units of pressure. Note this is a reversed axis.
legend	explains wind barb convention

Details

the dataframe must have components for wind speed wspd, wind direction dir, and pressure press. Missing values may be coded as either NA or 999. and are not plotted.
The standard atmospheric wind sybmol is a vector of fixed length with barbs proportional to wind speed. A full barb for each 10 m/s, half barbs for 5 m/s and a triangular barb for 50 m/s.

Value

None – creates a plot.
