The role of Turbulence in the Physics of Clouds

Objective

Earth’s dominant cloud type per area covered is Stratocumulus. These low-level, shallow, and Earth’s dominant cloud type per area covered is Stratocumulus. These low-level, shallow, and horizontally spread-out clouds cover one-fifth of the Earth’s surface. Changes in cloud cover may amplify rather than mitigate global warming but the magnitude of this is highly uncertain. One of the greatest challenges in climate science is to predict how clouds in general, and stratocumuli in particular, will change in a warming world. TurPhyCloud brings together 4 teams from Experimental and Theoretical Physics and Meteorology to address the full range of processes governing the formation of these clouds across scales, with particular attention to the role of turbulence. The team will (i) deliver high resolution in-situ measurements with unprecedented spatial resolution, from two field campaigns at Utö Atmospheric and Marine Research Station in the Baltic Sea capturing the full complexity of processes in midlatitude stratocumulus from submicrons to kilometres, (ii) derive statistical models for the turbulent processes of the cloud microphysics, not resolved by large-eddy simulations in a way that exceeds current parameterizations, in accuracy and resolution, (iii) will use their superdroplet method to incorporate the statistical models and use this to (iv) develop a new Microphysics Informed Large-Eddy-Simulation (MiLES) model, guided and verified by the results from the campaigns. The tested and verified MiLES will be embedded in weather and climate models. As a result, TurPhyCloud by a combination of unique measurements with realistic simulations of the MiLES model, will develop major advances in our understanding of how cloud-microphysical processes in stratocumulus interact with radiation and turbulence. TurPhyCloud will reduce uncertainties in climate projections and weather predictions through breakthroughs in measuring, modelling, and understanding stratocumulus dynamics.

Keywords

Project’s keywords as indicated by the project coordinator. Not to be confused with the EuroSciVoc taxonomy (Fields of science)

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
