Challenge: A poor understanding of the drivers of wind stress patterns over seas at scales of atmospheric convection
Change: Combinining ultra-high resolution satellite observations, simulations and local measurements of surface roughness and wind
Impact: More accurate wind stress formulations leading to improved high-resolution weather models and better understanding of satellite radar data.
Job description

The presence of rich flow structures in the atmosphere and ocean down to the scales of atmospheric convection O (100 m - 10 km) has sparked renewed interest across atmospheric and ocean scientists in recent years. How does this diverse wind structure influence the exchange of energy and momentum through the air-sea interface, and impact weather and climate? Marine cumulus clouds, especially during rain, are one of the drivers of large wind variability and leave a clear imprint on ocean surface roughness seen in high-resolution Synthetic Aperture Radar (SAR) imagery. These multi-scale, heterogeneous wind patterns may change the surface wind stress in ways we do not understand. Using ultra-high resolution satellite observations of ocean surface roughness, combined with large-eddy simulation (LES) and in-situ mooring/buoy data and ship-borne wind lidar, you will work closely together as a team to:

• Develop spatial maps of near-surface wind and wind stress from SAR, LES and wind lidar
• Quantify the influence of (sub)mesoscale spatial heterogeneity in wind, stability and surface roughness on wind stress
• Validate and improve formulations of wind stress
• Study the sensitivity of the atmosphere to (sub)mesoscale spatial heterogeneity in wind stress

You will be guided by Dr. Louise Nuijens, with expertise in wind-convection coupling using observations and LES, and by Dr. Paco Lopez-Dekker, with expertise in SAR retrievals and boundary layer processes. Your research will aid the development of space-borne wind stress retrievals and scale-aware surface flux parameterizations through connections to ESA, KNMI and ECMWF.
