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. Repeat using mapType=2 to see the smaller region over France. These different regions will be used in the following exercises. Animate the storm on this smaller geographical map. |

Click the play button Image Added at the top of the window to run this macro with the existing plots as shown above. Each plot can be a single field or overlays of different fields. 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". | Info |

Animating. If only one field on the 2x2 plot animates, make sure the menu item 'Animation -> Animate all scenes' is selected. Plotting may be slow depending on the computer used. This reads a lot of data files. |
