How Well Do High Resolution Ocean Models Simulate Local Turbulent Mixing?

Abstract information

The sea surface temperature of the tropical ocean impacts upon the whole climate and global atmosphere. In this video, MARTA MROZOWSKA explores how well ocean models reproduce near-inertial waves that deepen the mixed layer in the tropical sea via turbulent mixing. Running two ocean models of the tropical Atlantic, the research identified, among other things, that the simulated near-inertial currents are too weak and do not induce the observed turbulent mixing. Continuing research will draw on the new database of turbulence observations from Kiel's GEOMAR ocean research institute.

Researcher

Marta Mrozowska is currently finalizing her doctoral research at the University of Copenhagen’s Niels Bohr Institute with a thesis entitled “Upper Ocean Turbulence in Observations and Storm Resolving Climate Models”. Having previously completed her MSc (2021) and BSc (2019) at the University of Copenhagen, Mrozowska’s research interests include climate modeling and cross disciplinary oceanography. Between 2016 and 2021, Mzozowska helped to inspire young people’s interest in physics as a student instructor at the Niels Bohr Institute’s Ungdomslaboratoriet (ULAB).

Institution information

University of Copenhagen

With its more than 530 years, the University of Copenhagen is one of the oldest universities in Northern Europe. Being the largest institution of education and research in Denmark, the University has gone through numerous changes through the ages. The University of Copenhagen was inaugurated on 1 June 1479, after King Christian I was granted approval for its establishment by Pope Sixtus IV. Based on a German model, the university consisted of four faculties: Theology, Law, Medicine and Philosophy.
