.AilinBrakstad (Bjerknessenteret) applies a method of total matrix intercomparison to water mass properties to trace the Denmark Strait overflow water in the Nordic Seas. #IGPworkshop #oceanography

Jie Huang (Woods Hole Oceanographic Institution (WHOI) & Tsinghua University) investigates upstream sources of the North Icelandic Jet - a potential pathway between the Greenland and Iceland seas. #IGPworkshop #oceanography #potentialspicity

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. #IGPresearch #oceanography

Jake Opher (British Antarctic Survey 🐧 & UEA School of Environmental Sciences): - Denmark Strait overflow water has an annual cycle of salinity - Probably derives from lighter classes of DSOW source water #IGPworkshop #oceanography

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

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 #meteorology #YOPP #polarprediction

Andy Elvidge (UEA School of Environmental Sciences): #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 #IGPworkshop #meteorology #YOPP

Next, Ian Renfrew shows key features of atmospheric boundary layer in two cases of #ColdAirOutbreak over the Iceland sea. #IGPworkshop #meteorology #YOPP #polarprediction

More evaluation of operational and coupled versions of Met Office Science #UnifiedModel is presented by Chris Barrell #IGPworkshop #meteorology #YOPP #polarprediction

Some great analysis of boundary-layer mass, heat & moisture budgets calculated from radiosonde data by Chris Barrell #IGPworkshop #meteorology

Christiane Duscha (Geofysisk institutt) shows some early results of analysing #WindCube #lidar data, challenges during the #IGP campaign and how data can be corrected. #IGPworkshop #meteorology #YOPP #polarprediction

Alexandra Touzeau (Geofysisk institutt) presents aircraft measurements of water vapour #isotopes #IGPworkshop #meteorology #YOPP #polarprediction

Heidi Golid joins us from Geofysisk institutt 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. #IGPworkshop #meteorology #YOPP #polarprediction

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

Annick Terpstra (Geofysisk institutt & UEA School of Environmental Sciences): 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

And for dessert we have some more oceanography modelling of frontogenesis in the Denmark Strait done by Mike Spall and Bob Pickart Woods Hole Oceanographic Institution (WHOI) #IGPworkshop #oceanography MITgcm
