plotsonde

R Documentation

Creates a SKEW-T, log p diagram for a radiosonde dataframe.

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.

Usage

 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.
