Right-click on an_1x1.mv icon and select 'Edit'.
In the edit window that appears you can see the map types available covering a different area:
...
With mapType=0, the map covers a large area centred on the Atlantic suitable for plotting the analyses and track of the storm (this area is only available for the analyses).
With mapType=1, the map also covers the Atlantic but a smaller area than for the analyses. This is because the forecast data in the following exercises does not cover as large a geographical area as the analyses.
With mapType=2 , the map covers a much smaller region centred over France.
Change, mapType=0 to mapType=1 then click the play button 
at the top of the window.

Wind parameters can be shown either as arrows or as wind flags ('barbs') by adding '.flag' to the end of variable name e.g. "wind10.flag".
