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

Source: R/sounding_plot.R

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

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
