Die folgende Liste der Themen ist als Anhalt gedacht: • Modell eines Tornados: Drehimpulserhaltung, Unterdruck, herleiten wie groß die Windgeschwindigkeit und Unterdruck sind. • Magnetfeld Erde: Ausrechnen welche Sonnenteilchen/Kosmische Strahlen abgelenkt werden. Wie gefährlich wäre der Sonnenwind (vor allem coronal mass ejections) für Astronauten? • Autounfall: Ausrechnen bei welcher Geschwindigkeit ein Airbag noch Sinn macht bei einem Frontal-Zusammenstoß. • Alternative Energie: Ausrechnen wie viel Windmühlen und wie viel m^2 Sonnenzellen man braucht, damit Deutschland 100 Prozent auf neuerbare Energiequellen umgeschaltet ist. • Raketengleichung: Herleitung und Anwendung. Warum war die Saturn V Rakete so riesig, obwohl man mit einem Mini-Lunar Module von der Mond wegkommen konnte? • Flugzeugflügel: wieso können Flugzeuge fliegen? • Tsunamis: Shallow water equation für die Analyse von Tsunamis. Warum (und unter welchen Umständen) sind Tsunamis so gewaltig? • Blitze (Gewitter): Wie funktionieren sie ungefähr, und wie kann man die Lautstärke berechnen. Vielleicht eine Abschätzung davon, wie viel Hagelkörner man braucht um genügend Ladungs-Separation zu machen um überhaupt Blitze zu erzeugen. • GPS-Navigation: Spezielle und allgemein-Relativistische Effekte.
Goal
Die Studierenden sind in der Lage durch einfache mathematische bzw. physikalische Modelle selbstständig alltägliche physikalische Phänomene zu verstehen. Sie kennen Herangehensweisen bei der Bildung von Abschätzungen, durch die komplexe physikalische Phänomene durch geschickte Vereinfachungen und Annäherungen auf den Kernaspekt reduziert werden können. Sie sind in der Lage die weniger wichtigen Aspekte zu benennen, die vernachlässigt werden können, um so zu einem Verständnis zu kommen.

This lecture introduces all physical concepts of the fundamentals of Environmental Physics and it is accompanied by exercises and tutorials every week. The content spans: • The fundamentals about the Earth climate system and its compartments, flow, transport, and the global radiation balance. • Geophysical fluid dynamics, i.e. the fundamental laws of free and forced fluid movement and vorticity, and a practical guide to the first principles of turbulence. • Global circulation of atmosphere and ocean, boundary layer physics, and slow flow through porous media and of ice. • Gas and heat exchange between ocean and atmosphere. Global fluxes and cycles (energy, water, carbon). • Isotope fractionation and isotope methods to study the Earth environments, focus on water and carbon isotopes. • Introduction to models of environmental systems, basic principles of numerical climate modelling. • Basic principles of radiative transfer. Climate system radiative forcing and sensitivity. Global climate change past, present and future.
Goal
Students achieve a fundamental understanding of the key physical processes and interactions in the Earth surface system and its compartments, as well as of the human impact on these systems and the related societal implications. They are able to solve basic problems of environmental physics and interpret the results in the context of fundamental questions regarding the physics of the earth surface environments and the methodologies to observe and study those.

Code for registration will follow per e-mail to students registered here
General information
This platform – the physics department's exercise management system – serves for registration and for the electronic handling of the exercises (i.e., you can upload your solutions here).
The central platform for this lecture is the moodle page given above. There you will find the material for the lectures (lecture notes and slides, additional information and links) well in advance of the scheduled lecture times. You will also find exercise sheets with problems to solve for download there (but the upload of solutions is via this site here).
Videos for asynchronous study from the Covid years will also be made available via the moodle site. These videos will not be updated and are only meant as a backup for students who may not be able to attend in person at some dates.
Remarks on the contents
„Aquatic Physics“ or „Physics of Aquatic Systems“ is a part of environmental physics that deals with physical processes in natural waters such as oceans, lakes, rivers, and groundwater. The importance of studying the hydrosphere follows on the one hand from the sheer size of the oceans and their pivotal role in the climate system, on the other hand from the limited fresh water reserves and the related societal problems. The focus of this lecture lies on the most important continental water reservoirs, lakes and groundwaters. However, fundamentals of physical oceanography are also treated.
In the first part of the lecture, the physical properties of water and the aquatic systems, as well as the physical processes in these systems are treated. The laws of fluid dynamics (e.g., Navier-Stokes), as well as the theory of transport processes (e.g., advection, (turbulent) diffusion, heat and gas exchange), which are known from the general lecture on environmental physics (MKEP4) are applied to these special systems.
The second part of the lecture deals with the application of environmental tracer methods to study aquatic systems, the so-called isotope hydrology. In this part, various tracers (e.g., stable isotopes, 3H, noble and transient gases, 14C) and the basics of the respective methods are introduced and it is shown how these methods can be applied to determine physical parameters of aquatic systems.
The lecture "Physics of Aquatic Systems" is part of the Master programme in physics. However, it can also be heard by Bachelor students. Knowledge from the general lecture on environmental physics (MKEP4) is useful, but it is possible to hear this lecture in parallel to MKEP4.

Content
• Fundamentals of physical oceanography, limnology, and hydrogeology • Heat and mass transfer between water and atmosphere • Flow and transport in surface and ground water • Tracer methods in the hydrological cycle
Goal
Students achieve an advanced understanding of the physical processes in aquatic systems, the methods to study them, and their role in the climate system. They are able to solve advanced problems and interpret the results in the context of current questions in research and application. They can assess and use current scientific literature to further develop their knowledge base, enabling them to conduct independent master research projects in physics of aquatic systems.
