For these tasks, use the metview icons in the row labelled 'Analysis' an_1x1.mv : this plots horizontal maps of parameters from the ECMWF analyses overlaid on one plot. an_2x2.mv : this plots horizontal maps of parameters from the ECMWF analyses four plots to a page (two by two). an_xs.mv : this plots vertical cross-sections of parameters from the ECMWF analyses. |
Task 1: Mean-sea-level pressure and track
Right-click the mouse button on the 'an_1x1.mv' icon and select the 'Visualise' menu item (see figure right)
...
Now drag the mv_track.mv icon onto the map. This will add the track of Nadine. Note that although the track shows the full track of the tropical storm from the 10-09-2012 to 04-10-2016, the ECMWF analyses (for the purpose of this study) only show 15-09-2012 to 25-09-2012.
In the plot window, use the play button in the animation controls
to animate the map and follow the development and track of Hurricane Nadine....

Please close any unused plot windows if using a virtual machine. This case study uses high resolution data over a relatively large domain. Multiple plot windows can therefore require significant amounts of computer memory which can be a problem for virtual machines with restricted memory. |
Task 2: MSLP and 500hPa geopotential height
Right-click the mouse button on the 'an_1x1.mv' icon and select the 'Edit' menu item.
An edit window appears that shows the Metview macro code used to generate the plot. During these exercises you can change the top lines of these macros to alter the choice of parameters and plot types.

> 1 : Nadine MSLP and T2m (or better SST) tracking 15-20 september
> 2 : Satellite views on the 20th (provided by Etienne, if possible to put on the VM)
> 3 : Studying of the horizontal maps (analysis + forecasts)
