plotWind {RadioSonde}

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.
