651-4053-05L | Boundary Layer Meteorology | 4 credits | 3G | M. Rotach, P. Calanca | |

Abstract | The Planetary Boundary Layer (PBL) constitutes the interface between the atmosphere and the Earth's surface. Theory on transport processes in the PBL and their dynamics is provided. The course starts by providing the theoretical background and reviewing idealized concepts. These are contrasted to real world applications and discussed in the context of current research issues. | ||||

Objective | Overall goals of this course are given below. Focus is on the theoretical background and idealized concepts. Students have basic knowledge on atmospheric turbulence and theoretical as well as practical approaches to treat Planetary Boundary Layer flows. They are familiar with the relevant processes (turbulent transport, forcing) within, and typical states of the Planetary Boundary Layer. Idealized concepts are known as well as their adaptations under real surface conditions (as for example over complex topography). | ||||

Content | - Introduction - Turbulence - Statistical tratment of turbulence, turbulent transport - Conservation equations in a turbulent flow - Closure problem and closure assumptions - Scaling and similarity theory - Spectral characteristics - Concepts for non-ideal boundary layer conditions | ||||
