The Microphysics of Clouds research group at the Institute of Geophysics is searching for a PhD student to work in a project entitled ”Stochastic versus deterministic origin of warm rain” funded by the Polish National Science Centre.
Good understanding of rain production in clouds is necessary for numerical weather forecasting and for future climate prediction. There are some fundamental unresolved questions about the production of rain in liquid-water clouds. Rain in clouds is produced through collisions of cloud droplets. Some ”lucky droplets” can grow much faster than average droplets, thus leading to faster productionofrain. Ourresearchgroupstudiescloudsusinganovelnumericalmodel,Universityof Warsaw Lagrangian Cloud Model (UWLCM). The PhD student will apply the UWLCM to study the ”lucky droplets” effect.
The PhD student will have an opportunity to improve her/his programming skills by developing the UWLCM. UWLCM uses the Large Eddy Simulation model for ﬂuid ﬂow and a recently-developed Monte Carlo approach to Lagrangian modeling of water droplets (the superdroplet method). To achieve high performance, calculations are done simultaneously on CPUs and on GPU accelerators. The model is coded in C++ and uses OpenMP for multithreading and CUDA for GPU support. Implementation for distributed memory systems is currently being developed using Message Passing Interface. Computations will be performed on modern supercomputers, such as Prometheus at the Cyfronet AGH center.
