Walter & Lieth climatic diagram

Description

Plot of a Walter & Lieth climatic diagram of a station.

Usage

diagwl(dat, est = "", alt = NA, per = "", margen = c(4, 4, 5, 4), mlab = "",
  pcol = "#005ac8", tcol = "#e81800", pfcol = "cyan", sfcol = "#0eb6d7",
  shem = FALSE, ...)

Arguments

dat Monthly climatic data on which the diagram will be plotted.
est Name of the climatological station
alt Altitude of the climatological station
per Period of observation
margen Margins vector for the plot (to be passed to par).
mlab Month labels for the X axis:
"en":
Month initials in English.
"es":
Month initials in Spanish.
Other:
Numeric labels (1-12).
pcol Color pen for precipitation.
tcol Color pen for temperature.
pfcol Fill color for probable frosts.
sfcol Fill color for sure frosts.
shem Set to TRUE for southern hemisphere stations.
... Other graphic parameters

Details

Climatic data must be passed as a 4x12 matrix of monthly (January to December) data, in the following order:

Row 1:
Mean precipitation
Row 2:
Mean maximum daily temperature
Row 3:
Mean minimum daily temperature
Row 4:
Absolute monthly minimum temperature

This last row is only used to determine the probable frost months (when monthly values are equal or lower than 0°C). If shem=TRUE, the diagram will begin the plot with the July data, to keep the summer period in the central zone of the graphic.

Value

No value is returned by this function.
