Luise Schulte – Arctic mixed-phase clouds in the ECMWF model during the MOSAiC campaign
January 28 @ 16:00 - 17:00
CESOC continues the seminar series “My Research” this Winter term 2024/25 with a series of talks given by scientists from University of Bonn, University of Cologne and Research Centre Jülich.
This semester, we are excited to announce that the seminar series will be in a hybrid format and hosted by the different CESOC partners and it will also be streamed online (via zoom). The seminars will take place on Tuesdays on a bi-weekly basis at 16:00 hr.
on Tuesday, 28 Jan. 2025 at 16:00 (CET)
Luise Schulte
a Step-UP fellow at ECMWF and the Institute for Geophysics and Meteorology, University of Cologne, talking on their work
“Arctic mixed-phase clouds in the ECMWF model during the MOSAiC campaign”
It is open to any interested person within the CESOC research disciplines (any Earth system sciences, mathematics or computer science).
Please contact info[@]cesoc.net, if you would like to participate.
Full Schedule is available here!
Abstract:
How well do weather and climate models represent Arctic clouds? This talk introduces the role of clouds in the Arctic climate system and provides insight into why the prediction of clouds is challenging. We present results of our research in evaluating the representation of Arctic clouds in the ECMWF Integrated Forecasting System (IFS) using data from the year-long MOSAiC campaign. We explore how assumptions in cloud microphysics and sea-ice conditions influence the model’s predictions of supercooled liquid cloud water in cold temperatures and demonstrate the impact on surface radiation and temperature profiles. Our findings identify pathways to reduce biases in Arctic cloud representation and emphasise the value of long-term observations in refining Arctic cloud predictions.
