GC Rieber Climate Institute (Climate Processes Group): Physical climate knowledge to address societal challenges
The group focus the efforts on theoretical, numerical, statistical and observational studies of diverse climate shaping processes over multitude of spatial and time scales. The key element of these studies is an upscaling approach. We look at local processes and effects as they occur or percieved at local scales and seek for robust connections with large-scale climate processes and fundamental climate physics. This approach naturally splits the research in the following lines:
- High-resolution data: Technological solutions made a revolution in accessibility, diversity, density and, eventually, in the cost of environmental data. Significant mathematical and algorithmic advances are needed to develop: algorithmes to work with, to certify and to fuse new generation of high-resolution satellite data products, regular and citezens' observational networks, ground-born remote sensing instruments; methods to assimilate the high-resolution observations into climate models and statistical assessments.
- High-resolution modeling: Improved access to computational resources (inc. destop computing) unlocked the door for user-oriented environmental projects. Local physical processes in interaction, inter-scale dynamics and PBL data assimilation require: much better understanding; simulation of the planetary boundary layer dynamics with the large-eddy simulation technique.
- High-resolution user-oriented climate services: Post-modern environmentalism engages with society through “hot spots” focusing the public attention. Knowledge transfer is effective through resonant studies referring to the Traditional Environmental Knowledg. Studies of high-impact weather/climate phenomena require: high-resolution and visualizations; research on the links between the local and regional/global climate anomalies, uncertainty of the local climate projections, merging the modeling and observed climate statistics to detail the projects; co-design and co-development of market-oriented climate services with end-users.
At present, the group operates with: the Norwegian Earth System model and the Bergen Climate Model in cooperation with Bjerknes Centre for Climate Research; the large-eddy simulation model PALM in cooperation with the PALM Group; and the meteorological temperature profiler MTP-5HE.
