And for dessert we have some more oceanography modelling of frontogenesis in the Denmark Strait done by Mike Spall and Bob Pickart @WHOI

Annick Terpstra (@Geofysen & @ueaenv): most previous cold air outbreak & polar low climatologies depend too much on the SST pattern and can lead to misleading results.
Annick presents new synthesis of a refined CAO metric and mesoscale cyclone tracking.

The final session of #IGPworkshop starts with @meteodenny (@CollegeofEMPS) presenting recent work on North Atlantic polar mesoscale cyclones in #ERA5 and ERA-Interim reanalyses

Heidi Golid joins us from @Geofysen via skype to show the COSMO model validation against aircraft observations. Model accuracy increases with decreasing lead time and finer resolution. Optimal lead time +9 to +18 h.

Christiane Duscha (@Geofysen) shows some early results of analysing #WindCube #lidar data, challenges during the #IGP campaign and how data can be corrected.

Some great analysis of boundary-layer mass, heat & moisture budgets calculated from radiosonde data by @c_barrell

More evaluation of operational and coupled versions of @MetOffice_Sci #UnifiedModel is presented by @c_barrell

Next, @polarpredictian shows key features of atmospheric boundary layer in two cases of #ColdAirOutbreak over the Iceland sea.

Andy Elvidge (@ueaenv): #UnifiedModel surface turbulent heat fluxes have a positive bias compared to #IGP obs. Why? MIZ #seaice is too smooth. Also poor representation of surface roughness. Similar model biases are likely in @ECMWF #IFS

Day 2 of #IGPworkshop is kicked off by the overview of aircraft observations of surface heat fluxes over the marginal ice zone presented by Andy Elvidge

And now it's time to continue the #IGPworkshop discussion in a pub!

Jake Opher (@BAS_News & @ueaenv):
- Denmark Strait overflow water has an annual cycle of salinity
- Probably derives from lighter classes of DSOW source water

Stefanie Semper: Iceland-Faroe Slope Jet shows up in drifter trajectories and numerical models. It exhibits 3 cores of overflow water, has a dense transport mode similar to the NIJ, and shows no significant evolution of the transport mode in T or S.

Jie Huang (@WHOI & @Tsinghua_Uni) investigates upstream sources of the North Icelandic Jet - a potential pathway between the Greenland and Iceland seas.
