Meryl WIMMER
Biography
Meryl WIMMER received the Ph.D. degree in atmospheric sciences from the Université Toulouse III – Paul Sabatier, France, in December 2021.
Her doctoral research, realized at Météo-France, was on the model error representation in AROME-EPS, the convection-permitting Ensemble Prediction System operational at Météo-France. During that research, she was interested in the sensitivity of the AROME model to uncertain parameters and in the optimization of perturbed parameters approaches in AROME-EPS.
In previous research, she has also worked on the impact of deep convection parameterization scheme on the jet stream and on an extratropical cyclone.
She is currently a CNES (Centre National d’Études Spatiales) post-doctoral researcher at the Laboratoire de Météorologie Dynamique in Paris, France, where she studies the sensitivity of Arctic Cyclones forecasts to cloud microphysics parameterization schemes.
