Irina joined ECMWF in 2010, and is now leading the Physical Processes Team. Her research has so far covered boundary layer clouds and the factors controlling their distribution, aerosol-cloud interactions, turbulent diffusion in stable conditions, orographic drag and land-atmosphere coupling. Irina used a whole spectrum of models (from idealized theoretical models, to Large Eddy, meso-scale and global NWP models), but also a wide range of datasets (in situ observations, satellite data and reanalysis) to address questions ranging from process understanding to aspects of subgrid parameterizations and model evaluation.
At ECMWF, Irina's work aims at improving the representation both stable and cloudy boundary layers in the Integrated Forecasting System, and at understanding the impact of surface drag on the large scale atmospheric circulation. In recent years, Irina played an instrumental role in reviving the interest of the international community for the drag processes, and the orographic drag in particular, by highlighting their importance for the large-scale circulation and the uncertainties related to their representation in models. Irina is also now coordinating polar prediction related activities at ECMWF, particularly in the context of the ongoing WMO Year of Polar Prediction and the H2020 project APPLICATE.
