ws_warm_front

../../_images/WS_WARMFRONT.png

Defines a warm front Weather Symbol Object that can be visualised with plot().

New in Metview version 5.15.0.

Warning

The script-based Weather Symbol Object visualisation is currently restricted to the ‘screen’ output target (i.e. when the output is Metview’s plot window). On the one hand this requires the Metview GUI to be installed, on the other hand it limits the script-based visualisation to these cases:

  • execute the code in Metview’s Code Editor (the default output target here is already ‘screen’)

  • execute the code as a Jupyter notebook with the output target set to ‘screen’ (see setoutput()):

In any other cases, e.g. in batch mode, plot() does not work.

Note

This function performs the same task as the Ws Warm Front icon in Metview’s user interface. It accepts its parameters as keyword arguments, described below.
