For this exercise, you will use the Metview icons in the folder 'HRES_forecast' shown above.

hres_1x1.mv & hres_2x2.mv : these work in a similar way to the same icons used in the previous task where parameters from a single lead time can be plotted either in a single frame or 4 frames per page.hres_xs.mv                                        : this plots a vertical cross section and can be used to compare the vertical structure of Hurricane Nadine and the cut-off low.

     : for this exercise, this icon can be used to overlay the forecast track of Nadine (and not the track from the analyses as in Exercise 1)

• "vo850", "mslp"        : vorticity at 850hPa and MSLP – low level signature of Nadine and disturbance associated with the cut-off low.
• "r700", "mslp",          : MSLP + relative humidity at 700hPa – with mid-level humidity of the systems.
• "pv320K", "mslp"     : 320K potential vorticity (PV) + MSLP – upper level conditions, upper level jet and the cut-off low signature in PV, interaction between Nadine and the cut-off low.
• "wind850", "w700" : winds at 850hPa + vertical velocity at 700hPa (+MSLP) – focus on moist and warm air in the lower levels and associated vertical motion.
• "t2", "mslp"                : 2m-temperature and MSLP – low level signature of Nadine and temperature.
• "mslp", "wind10"     : MSLP + 10m winds – interesting for Nadine's tracking and primary circulation.
• "t500","z500"               : geopotential + temperature at 500hPa – large scale patterns, mid-troposphere position of warm Nadine and the cold Atlantic cut-off low.
• "eqpt850", "z850"     : geopotential + equivalent potential temperature at 850hPa – lower level conditions, detection of fronts.

Q. How strongly does Nadine appear to interact with the cut-off low?
Q. What is the fate of the cut-off low and what synoptic conditions did it create over France?
