Theses Topics

Students are welcome at IAP. Topics for bachlor or master theses can be found in the following list. If you are interested or have any questions, please contact the persons mentioned below each project.

  1. Analysis of the dependence of mid-latitude noctilucent clouds (NLC) on ambient winds based on local lidar and radar soundings. In this study a quantitative analysis of the correlation between wind parameters and the occurrence of NLC is desired. So far, qualitative analyses clearly indicate the dependence of NLC on "favorable" winds, but quantitative studies at mid-latitudes are pending. (Dr. M. Gerding, Optics)
  2. Analysis of the sensitivity of different IR cameras for cloud detection. Clouds differ by their radiative temperature (i.e. their height) and optical thickness. In this study different IR cameras shall be tested and compared with respect to their qualification for cloud detection. Visual range cameras,  weather models and active cloud detectors will provide complementary data. (Dr. M. Gerding, Optics)
  3. High-resolution volumetric radar observations of polar mesospheric summer echoes (PMSE) with the Middle Atmosphere Alomar Radar System (MAARSY): visualization, analysis and characterization of 4D radar images of polar mesospheric summer echoes. (Prof. J. L. Chau and Dr. M. Urco, Radar)
  4. Statistical analysis of the mesopause dynamics at different latitudes: Multi-year wind data from 8 to 100 km in height are available from IAP radar measurements. They cover the latitudes: 49 °S, 12 °S, 5 °S, 54 °N, 69 °N. The project includes the analysis of mean winds and dominant planetary waves and tides at these latitudes and their comparisons (Dr. J. F. Conte, Radar)
  5. DNS simulations of Kelvin-Helmholtz instabilities with Dedalus: In this project, numerical investigations of mesoscale instabilities at different Reynolds numbers and stratification rates are to be carried out. (Prof. J. L. Chau, Radar)
  6. The derivation of electron number densities from cross-polarized radar measurements: The Saura MF radar with its operating frequency (3MHz), a modular structure and polarization configuration is able to determine the electron density of the lower ionosphere by the measurement of absorption and Faraday rotation. This project aims to combine both absorption and Faraday information with regularization techniques to derive improved electron density profiles. (Dr. T. Renkwitz, Radar)
  7. Subseasonal prediction with machine learning: Use machine learning to predict/reconstruct some easy variables such as minimum/maximum temperature and wind speed some weeks ahead using reanalysis data, model simulations and instrumental observations. (Dr. M. Amiramjadi, Modelling)
  8. Statistical properties of sudden stratospheric warmings: The statistical properties of these large-scale circulation patterns are determined from reanalysis data – a valuable information source for local observations. (Dr. Ch. Zülicke, Modelling)
  9. Kinetic helicity – a tool for analysis of gravity waves and stratified turbulence: The kinetic helicity is the product of velocity and vorticity. We will conduct theoretical studies of this parameter and use simulation data to quantify its consequences on mesoscale dynamics (Dr. V. Avsarkisov, Modelling)
  10. Optimization of background determination for improvement of lidar measurements: A time series of a point measurement in Kühlungsborn or Alomar is artificially generated from wind/temperature fields of the global model KMCM. With them, different approaches for the determination of background fields are tested, which can be used in lidar measurements.(Dr. Urs Schaefer Rolffs, Modelling, und Dr. Irina Strelnikova, Optics)
