An Integrated View of Boundary Layers and Turbulence: Theories, Experimental Data, and Numerical Models

The boundary layer near the Earth’s surface is the region in which we spend most of our lives. The scales of turbulent motions in atmospheric and oceanic boundary layers are typically smaller than the horizontal grid spacing of regional and global models, calling for parameterization schemes describing the net effect of these subgrid-scale motions. My vision is to bridge the theoretical understanding of turbulent boundary layers and the demands from regional and global models. 

EOL Seminar Series: Dr. Emma Järvinen "Understanding the interaction of solar radiation with cirrus ice crystals – implications for the radiative transfer and climate modelling"

There exists still a great uncertainty in understanding the magnitude and even the sign of the cirrus short wave radiative effect. Partly, this is due to the difficulties of modelling and parametrizing the radiative properties of usually non-spherical ice crystals that tend to be found in various shapes and sizes in the atmosphere. Furthermore, recent modelling and laboratory studies have given evidence that including microscale complexities, such as surface roughness, will further change the ice crystal light scattering properties.
