Cold pools are an extremely relevant atmospheric phenomenon. Their gust front is the main cause of damages from convection and thunderstorms. They are a key factor in the organization of atmospheric convection by triggering subsequent convection. Scientifically, cold pools are now a very timely topic as they become resolved by the next generation of kilometer-scale weather and climate models. Join the project to help fill the corresponding observational gap.

You will benefit from the ground-breaking FESST@HH and FESSTVaL (www.fesstval.de) observational campaigns, which provide the first spatial measurements of near-surface cold pool evolution using dense station networks. Your research may involve:

• developing multivariate, machine-learning methods to detect cold pools in conventional surface observations andrem ote sensing data using FESSTVaL training datasets
• investigating the controlling factors that shape cold pool characteristics, such as strength or propagation speed
• characterise the full life cycle of cold pools with emphasis on the decay phase to derive constraints for model evaluation
• perform own targeted field work to complement the observational data setverifica tion and optimisation of the cold pool representation in the ICON model at convection resolving resolution together with the German Meteorological Service (DWD)

You will benefit from the vibrant research environment in Hamburg. As a PhD student, you can join the IMPRS or SICCS graduate schools. You will work closely with the neighbouring Max Planck Institute for Meteorology and the German Climate Computing Centre on cold pool simulations. The project is part of the OceanWeather project of the Hans Ertel Centre for Weather Research (HErZ). HErZ funds six universities to carry out basic research on current research topics of the DWD. Intensive collaboration with the DWD and the university partners, as well as access to DWD infrastructures, ensures a stimulating research environment at the highest level.
