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.
#IGPworkshop #meteorology
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

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

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

.@AilinBrakstad (@BjerknesBCCR) applies a method of total matrix intercomparison to water mass properties to trace the Denmark Strait overflow water in the Nordic Seas.

Kent Moore (@UofT): recent #seaice retreat reduces the air-sea interaction over the Iceland & Greenland seas. New results from @CopernicusECMWF #ERA5. East Greenland current is being exposed to the atmospheric forcing. Impact on the DSOW formation to be determined.
#IGPworkshop
Change in #seaice and SST is important both for Iceland Sea and Greenland Sea gyres. However, reduced sea ice in the Greenland Sea counter-intuitively leads to larger sensible heat flux.

Next, @JamesPope10 starts the #atmospheric session of #IGPworkshop by showing nested simulations of @MetOffice_Sci #UnifiedModel
Bob Pickart (@WHOI) presents a revised picture of Denmark Strait water circulation: boluses vs pulses modes of variability, warm floodings, baroclinic instability of the NIIC front.
Blending observations with @MITgcm simulations.

Deep water formation and circulation in the north-west Iceland Sea (Eggvin Offset) presented by @SiljeSkjelsvik #IGPworkshop #YOPP #oceanography
Kjetil Våge (@Geofysen): using data from several campaigns, we can say that the Iceland Sea may have been more important as a source of dense water to the NIJ and the Denmark Strait in the past decades. Recent warming and reduced sea ice => less atmos forcing #IGPworkshop #YOPP
Stefanie Semper (@Geofysen): the North Atlantic Jet is visible in mooring data, exhibits a double-core structure. Contributes to the Denmark Strait overflow. Shows no consistent link to atmospheric forcing, but may be subject to barotropic or baroclinic instabilities #IGPworkshop
Next up in #IGPworkshop it's Stefanie Semper talking about the emergence and evolution of the North Icelandic Jet
#YOPP #polarprediction #oceanography
Oh, to be a drone on the wall of #INFORMNJ #IGPworkshop where dynamic duo of @ARMA_INT @nickinglis and President-elect @JCStearns_CRM trail blaze info practitioners deep into the data-in-the-wild thicket.
