AbstractThe Planetary Boundary Layer (PBL) constitutes the lower part of the atmosphere, is characterized by turbulent mixing and ensures the exchange of energy, mass and momentum between the Earth’s surface and the atmosphere. The course provides the theoretical background for understanding the structure and dynamics of the PBL. Idealized concepts are reviewed and contrasted to real world applications.
ObjectiveStudents are able to:
- Name the basic approaches needed to describe planetary boundary layer flows and associated turbulent exchange processes.
- Apply these concepts to answer comprehension questions and solve simple problems related to the structure and dynamics of the PBL.
- Independently judge the applicability of learned concepts and tools to real-world situations.
Content- Introduction
- PBL structure and stability
- Turbulence and turbulent transport
- Scaling and similarity theory
- Spectral characteristics
- Conservation equations in a turbulent flow
- Closure problem and closure assumptions
- Rough surfaces and the roughness sublayer
- Complex terrain
