In thunder: Computation and Visualisation of Atmospheric Convective Parameters

Plot Skew-T, hodograph and convective indices on a single layout

Description

Function to plot a composite graphics with Skew-T, hodograph and selected convective parameters on a single layout

Usage

sounding_plot(
  pressure,
  altitude,
  temp,
  dpt,
  wd,
  ws,
  title = "",
  parcel = "MU",
  max_speed = 25,
  buoyancy_polygon = TRUE,
  SRH_polygon = "03km_RM",
  DCAPE = FALSE,
  meanlayer_bottom_top = c(0, 500),
  storm_motion = c(999, 999),
  ...
)

Arguments

pressure	pressure [hPa]
altitude	altitude [m] (can be above sea level or above ground level as function always consider first level as surface, i.e h = 0 m) - altitude [meters]
temp	temperature [degree Celsius]
dpt	dew point temperature [degree Celsius]
wd	wind direction [azimuth in degrees]
ws	wind speed [knots]
title	title to be added in the layout's header
parcel	parcel tracing on Skew-T for "MU", "ML" or "SB" parcel, "none" for no parcel line.
max_speed	range of the hodograph to be drawn, 25 m/s used as default
buoyancy_polygon	logical, plotting area of parcel's positive (yellow) or negative (red) buoyancy (default = TRUE)
SRH_polygon	draws polygon for storm-relative helicity, available options are "0500m", "01km", "03km", "36km", "none", "03km" used as default
DCAPE	draws downdraft parcel and polygon of downdraft's negative buoyancy (default = FALSE)
meanlayer_bottom_top	(optional) vector of length 2 for bottom and top heights used for computing parcel starting parameters; default: 0, 500
storm_motion	(optional) for moving storms only - one can define vector of length two with wind speed [m/s] and wind directions [degrees] that will be used to compute adjusted SRH parameters
...	extra graphical arguments to be added

Value

panel of Skew-T, hodograph and table with convective indices drawn on a pre-defined single layout

Examples

data("sounding_vienna")
sounding_vienna = na.omit(sounding_vienna)
sounding_plot(sounding_vienna$pressure, sounding_vienna$altitude,
  sounding_vienna$temp, sounding_vienna$dpt,
  sounding_vienna$wd, sounding_vienna$ws,
  parcel = "MU", title = "Vienna - 23 August 2011, 12:00 UTC"
)
