| Abstract | This course covers the basics of atmospheric physics, which consist of: cloud and precipitation formation especially prediction of thunderstorm development, aerosol physics as well as artificial weather modification.

| Learning objective | Students are able - to explain the mechanisms of thunderstorm formation using knowledge of thermodynamics and cloud microphysics. - to evaluate the significance of clouds and aerosol particles for artificial weather modification. | |||||||||||||||||||||||
| Content | The course starts with introducing selected concepts of thermodynamics for atmospheric processes: The students learn the concept of the thermodynamic equilibrium and derive the Clausius-Clayperon equation from the first law of thermodynamics. This equation is central for the phase transitions in clouds. Students also learn to classify radiosondes with the help the thermodynamic charts (tephigrams) and to identify cloud base, cloud top, available convective energy in them. Atmospheric mixing processes are introduced for fog formation. The concept of the air parcel is used to understand convection. Aerosol particles are introduced in terms of their physical properties and their role in cloud formation based on Köhler theory. Thereafter cloud microphysical processes including ice nucleation are discussed. With these basics, the different forms of precipitation formation (convective vs. stratiform) is discussed as well as the formation and different stages of severe convective storms. The concepts are applied to understand and judge the validity of different proposed articifical weather modification ideas. | |||||||||||||||||||||||

| Prerequisites / Notice | 50% of the time we use the concept of "flipped classroom" (en.wikipedia.org/wiki/Flipped_classroom), which we introduce at the beginning. We offer a lab tour, in which we demonstrate how some of the processes discussed in the lectures are measured with instruments. There is a additional tutorial right after each lecture to give you the chance to ask further questions and discuss the exercises. The participation is recommended but voluntary. | |||||||||||||||||||||||

| 701-1235-00L | Cloud Microphysics Number of participants limited to 16. Priority is given to PhD students majoring in Atmospheric and Climate Sciences, and remaining open spaces will be offered to the following groups: - PhD student Environmental sciences - MSc in Atmospheric and climate science - MSc in Environmental sciences All participants will be on the waiting list at first. Enrollment is possible until September 22nd, 2021. The waiting list is active until October 1st, 2021. All students will be informed on September 16th, if they can participate in the lecture. The lecture takes place if a minimum of 5 students register for it. | 4 credits | 2V + 1U | U. Lohmann, N. Shardt | ||||||||||||||||||||
| Abstract | Clouds are a fascinating atmospheric phenomenon central to the hydrological cycle and the Earth`s climate. Interactions between cloud particles can result in precipitation, glaciation or evaporation of the cloud depending on its microstructure and microphysical processes. | |||||||||||||||||||||||
| Learning objective | The learning objective of this course is that students understand the formation of clouds and precipitation and can apply learned principles to interpret atmospheric observations of clouds and precipitation. | |||||||||||||||||||||||

| Lecture notes | This course will be designed as a reading course in 1-2 small groups of 8 students maximum. It will be based on the textbook below. The students are expected to read chapters of this textbook prior to the class so that open issues, fascinating and/or difficult aspects can be discussed in depth. | |||||||||||||||||||||||
