„Mountain Meteorology - Models, Observations, Processes“

• Date fixed: Thursday, 5.10.2023 and Friday, 6.10.2023
• each talk will be based on at least 2 publications
• one is suggested by an advisor (see below), the other will be added by the student
• 30 min presentation, 10-15 minutes discussion
• Language: English or Deutsch
• all participants attend all presentations
• all participants contribute to the discussions

We expect all students who want to take part to:

1. Select one paper and register with the given advisor and Tobias Zinner until 15 August 2023.
2. Look for a second paper connected to your selection
   • use Web of Knowledge/ Web of Science or Google Scholar
   • Link to LMU Bib search
   • Link to E-Medien-Login (use your LMU-Kennung)
   • University databases for geosciences
3. Discuss with your advisor the literature you plan to use for your presentation soon, well in time before the final preparation of the slide material.
4. Talk to your advisor at least one more time before the seminar. At this meeting you should go through the final presentation material in time for last changes. Consequently, this should take place shortly before the seminar in October.
