a) Task 1: 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) Task 2: 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. | Panel |

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. Task 3: Change the fields plotted to include the wind arrows. Make sure you have the Edit window showing. | Code Block |

As above, click the play button and then animate the map that appears. You might also want to change the mapType back to 'mapType=1' to show the larger geographical area. 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.
If you prefer to see multiple plots per page rather than overlay them, please use the an_2x2.mv macro. |
