The 2019 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Iris Thurnherr for the poster/PICO entitled:
How air-sea interactions are modulated by synoptic weather systems: a stable water isotope perspective (Thurnherr, I.; Aemisegger, F.; Graf, P.; Pfahl, S.; Hartmuth, K.; Jansing, L.; Böttcher, M.; Gehring, J.; Berne, A.; Sodemann, H.; Gorodetskaya, I.; Wernli, H.)

Iris Thurnherr is a PhD student in the Atmoshperic Dynamics group at ETH Zurich, Switzerland. Her research focuses on stable water isotope (SWI) meteorology, field measurements of SWIs and SWI modeling in numerical weather models. During her PhD, she is investigating air-sea interactions using ship-based SWI measurements in water vapour from the Southern and Atlantic Ocean.
In her PICO presentation at EGU 2019, she presented the use of SWI measurements in water vapour to characterise air-sea interaction in the cold and warm sectors of extratropical cyclones and showed that ocean evaporation, precipitation and water vapour deposition on the ocean surface triggered by the advection of cold and warm air masses leave distinct SWI signals in marine boundary layer air masses.
