Description

Creates a SKEW-T, log p diagram with dry-bulb temperature and dewpoint temperature traces versus (log) pressure. Optionally plots the vertical wind profile using wind barbs.

 plotsonde(dataframe, skewT=TRUE, winds=FALSE, site="", title="",
           windplot=NULL, s=3, col=c(1, 2), ... ) 

Arguments

dataframe

R dataframe with at least the components c( "press", "temp", "dewpt") corresponding to pressure (hPa), temperature (C) and dew point temperature (C).

skewT

Logical value. If false, will not plot the SKEW-T, log p diagram.

winds

Logical value. If false, will not plot the winds profile.

site

Optional character to add to plot title.

title

Title for plot (must be a character value).

windplot

4X1 numeric vector that gives the position of wind profile plot (next to SKEW-T diagram). Only used if it is desired to have this plot in a different position. Generally, the default NULL is used and the placement is chosen automatically.

s

Size of winds profile plot.

col

Usual plotting parameter.

...

Other optional plotting parameters.

Value

No value returned. Creates a skewt plot. Note that default is temperature horizontal scale is Farenheit.
