a) Right-click the mouse button on the 'an_1x1.mv' icon and select the 'Visualise' menu item (see figure right)

After a few seconds, this will generate a map showing two parameters: mean-sea-level pressure (MSLP) and 3hrly max wind-gust at 10m (wgust10).

Use the play button to animate the map and follow the development and track of the storm.

You can use the 'Speed' menu to change the animation speed (each frame is every 3 hours).

 

b) Right-click the mouse button on the 'an_1x1.mv' icon and select the 'Edit' menu item (see figure right).

An edit window appears that shows a number of lines of 'Metview macro' code. During these exercises you can change some of these to alter the parameters and plot types.

titleTwo map types are available covering a different area

With mapType=0, the map will cover a smaller geographical area centred on the UK.

With mapType=1, the map will cover most of the North Atlantic

 

Change, mapType=0   to   mapType=1   then click the play button at the top of the window (please ask if you are not sure).

Animate the storm on this smaller geographical map.

  • Each team member can then choose their own parameters; look at the fields on different pressure levels; use the smaller geographical area (mapType=0) to compare with the observations.

    • Discuss the storm development and behaviour with your colleagues & team members.

     

    That completes the first exercise.

    If time:

    • You are encouraged to explore the storm development and passage using the other parameters available on other pressure levels
    Discuss the storm characteristics and development
    • .

    If you prefer to see multiple plots per page rather than overlay them, please use the an_2x2.mv macro.

    titleChange plot fields

    For the 'an_1x1.mv' icon, the plot contents can be changed by editing the plot1 variable in the macro. By default the 10m wind is shown.

    To alter the plotted field, right-click and choose 'Edit'.

    It is possible to overlay multiple fields like this:

    You will find a list of available parameters in the macro.

    After editing the macro text, you can optionally save using the 'File' menu and 'Save'.

    Display the plot by clicking:

    titleChange plot appearance

     The number of maps appearing in the plot layout can be 1, 2, 3 or 4.

    Macro an_2x2.mv demonstrates how to plot a four-map layout in a similar fashion to the one-map layout. The only difference here is that you need to define four plots instead of one.

    Right-click on the icon and select 'Edit'. Change the plot layout like this:

    Two map types are available covering a different area.

    With mapType=0, the map will cover a smaller geographical area centred on the UK.

    With mapType=1, the map will cover most of the North Atlantic
