TO BE DONE (flowchart as last year?0

• Study track & development of Hurricane Nadine and the N.Atlantic cut-off low
• Study HRES & ENS forecasts of the time
• Study HRES & ENS forecasts using the 2016 ECMWF ensemble forecast
• .... PCA analysis ..
• ...etc...

...

After a pause, this will generate a map showing mean-sea-level pressure (MSLP).

Now drag the mv_track.mv icon onto the map. This will add the track of Nadine. Note that although the track shows the Although the full track of the tropical storm is shown 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.

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.

#Available parameters:
# mslp,t2,wind10,speed10,sst
# t,z,pt,eqpt [850,700,500,200]
# wind,speed,r[925,850,700,500,200]
# w700, vo850, pv320K

The surface fields (single level) are: MSLP (mean-sea-level-pressure), 2-metre temperature (t2), 10-metre wind arrows (wind10), wind-speed at 10m (sqrt(u^2+v^2): speed10), sea-surface temperature (sst).

The upper level fields are: temperature (t), geopotential (z), potential temperature (pt), equivalent potential temperature (eqpt), wind arrows (wind), wind-speed (speed), relative humidity (r).

These fields have a list of available pressure levels in square brackets.

To plot upper level fields, specify the pressure level after the name. e.g. z500 would plot geopotential at 500hPa.

Some extra fields are also provided: vertical velocity at 700hPa (w700), relative vorticity at 850hPa (vo850) and potential vorticity at 320K.

Wind fields are normally plotted as coloured arrows. To plot them as wind barbs add the suffix 'f'. e.g. wind10f will plot 10m wind as barbs.
