Winds Profile Plot

Share:

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

1
 plotwind(dataframe, size=5, ylim=c(1050, 100), legend=FALSE) 

Arguments

dataframe

Data frame for sounding data, must have components for wind speed wspd, wind direction dir, and pressure press.

size

change the thickness of the plotted lines

ylim

plot extent, in units of pressure

legend

explains wind barb strategy

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.
