plotsonde {RadioSonde} 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=T, winds=T, site="", title="",
           windplot=NULL, s=3, col=c(1, 2), ... )

Arguments

dataframe R dataframe of a radiosonde dataset (as created by getsonde)
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 plot.
