Personal profile

Personal profile

Janneke Ettema (1978) is an assistant professor in 'Natural hazards and Climate Change' at the Earth Systems Analysis department in the Faculty of Geo-information and Earth Observation (ITC) of University of Twente, the Netherlands. Janneke Ettema earned a PhD degree (2010) in Meteorology from the Institute of Marine and Atmospheric research Utrecht (IMAU) at Utrecht University in the Netherlands and a MSc degree in Soil, Water and Atmosphere (specialization Meteorology) from the Wageningen University, the Netherlands (2001). Between finishing her MSc and starting a PhD, Janneke worked 2 years at the Royal Netherlands Meteorological Institute (KNMI) in De Bilt, the Netherlands on extreme wind assessment for the Dutch dike system. Additionally, she worked as consultant at the European Medium-Range Weather Forecasts (ECMWF ) in Reading, UK, where she focused on development and evaluation of a soil moisture data assimilation to improve the weather forecasting system for Europe. For her PhD, she studied the present-day climate and surface mass balance of Greenland and its ice sheet under the supervision of Prof. Dr. Michiel van den Broeke, Prof. Dr. Hans Oerlemans and Dr. Erik van Meijgaard (KNMI). By using an advanced regional atmospheric climate model (RACMO), changes in spatial and temporal distribution of atmospheric and surface processes could be analysed over the period 1957-2008. An unprecedented high horizontal resolution of 11 km led to new insights in the spatial patterns and temporal trends in surface mass fluxes that contribute to the total growth/loss of ice mass over the ice sheet. At ITC, her professional view has widened to hydro-meteorological hazards and climate change. The role of the meteorological processes in hazard related topics is her main focus. Hazards are often caused by extreme weather events, it is essential to get better understanding of the underlying triggering atmospheric processes and their relation to e.g. local land use.


Janneke lectures MSc-topics as meteorological processes, meteorological hazards, atmospheric modelling and climate change. She supervises MSc students in the field of hydro-meteorological hazards and climate change, e.g. on impact changing drought conditions on risk assessment and monitoring extreme Indonesian rainfall events.

Research interests


Janneke's main research interest is the making of the link between meteorological processes and hydro-meteorological hazards world-wide. Her main focus is on modelling of land-atmosphere interactions and applications in climate, hazard and water resources studies E.g. within Marie Curie project CHANGES, she co-supervises a PhD-student working on the translation of changing meteorological triggering conditions for flood and landslide modelling. Getting a better understanding of the meteorological triggering conditions of hydro-meteorological hazard will provide insight on how downscaling of future climate scenarios could be optimized. Additionally, she is involved in climate scenario development for countries in Southeast Asia.
