set xflip Flips the order of the horizontal axis

admin بازدید : 42 چهارشنبه 09 شهريور 1401 نظرات (0)

set xflip

set xflip on|off

Flips the order of the horizontal axis (whatever axis is horizontal after xyrev is applied). Reset by a clear or set vpage command.

Usage Notes

Examples

'set lat 20 45'

'set lon 40 60'

'set xflip on'

' display u,v'

set xyrev Reverses the axes on a plot

Rotate the axis on the map

set xyrev

set xyrev on|off

Reverses the axes on a plot.

Usage Notes

Examples

By default for a Z, T plot, the time dimension is plotted horizontally, and the Z dimension is plotted vertically. By setting xyrev, the time dimension would be plotted vertically and the Z dimension would be plotted horizontally. Reset by a clear or set vpage command.

Script: theta.gs; Defines potential and equlivalent potential temperature given temperature and moisture inputs

admin بازدید : 93 شنبه 05 شهريور 1401 نظرات (0)

This script, is really more of a function, the best way to use this would be to copy the contents of this script into the bottom of the script you wish to use it in.  This function reads in temperature and moisture information and returns a good approximation of both potential and equivalent potential temperature.

This function asks for up to four inputs, though only temperature and moisture inputs are required.
It is capable of calculating  equivalent potential temperature given four different moisture input variables:

  1. Relative Humidity (-rh)
  2. Mixing Ratio (-r)
  3. Vapor Pressure (-e)
  4. Specific Humidity (-q)

The default is relative humidity.
