2. Project A02: 1 PhD student position, Reference: SFB1114-A02-a
Multiscale data and asymptotic model assimilation for atmospheric flows

Job description:

To take advantage of the observational record in numerical weather forecasts one merges the history of previous forecasts with past and up-to-date observations through data assimilation procedures. The resulting effective dynamical system incorporates the spacio-temporal hierarchies of characteristic scales from both the atmospheric flow simulation model and the observation system. This project aims at building a coherent mathematical framework for multiscale analyses of such systems based, among others, on stochastic modeling, Bayesian inference, and multiple scales asymptotics. The work programme for the present position is centered on the multiscale analysis of weather prediction / data assimilation systems. Successful candidates are expected to pursue mathematical and interdisciplinary research on the international level, to publish the results in international scientific journals and to present the results on national and international conferences and workshops.
