200-hPa Ozone Mixing Ratio and Geopotential Height & Cross-Sections

200-hPa maps:
          200-hPa Ozone mixing ratio
● The location of the local maximum of the ozone mixing ratio gradient (where local = 10˚ from Goose Bay, NL, Canada).
● Location of Goose Bay, NL, Canada.
/ Cross section parallel to the gradient vector extending 1000 km from ●
The 1500 km range ring from Goose Bay.
≈ 200-hPa geopotential height.

Cross Sections:
        Ozone mixing ratio
        Relative humidity
— Potential temperature (every 5 K).
— The dynamic tropopause (2 PVU contour).
— Cross-section normal wind (m/s).
★ The location of the local minimum in the dynamic tropopause potential temperature from previous map.
● Largest potential temperature gradient within 5˚ of local min potential temperature.
