1. 1. Zeeman Doppler Imaging of the eclipsing binary UV Piscium

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Axel Hahlin; [2020]
   Keywords : Magnetic fields; polarisation; eclipsing binary;

   Abstract : Magnetic fields are important for multiple physical processes in and around stars, for these reasons improving the understanding of how they are generated and maintained is of great value. In this work the magnetic field structure of the eclipsing binary UV Piscium is investigated. READ MORE

3. 2. Searching for atmospheric signals in states of low Antarctic sea ice concentration

   University essay from Stockholms universitet/Meteorologiska institutionen (MISU)

   Author : Aiden Jönsson; [2018]
   Keywords : Sea ice; atmospheric circulation; Antarctic; polar; moisture transport;

   Abstract : The Antarctic sea ice region is relatively stable in extent from year to year and sees little long-term variability, the primary driver for its seasonal advance and retreat being the seasonal changes in advection of heat through the atmosphere. However, observations show a slight positive trend in its extent over recent decades. READ MORE

   Abstract : Tanks are storage vessels for liquids. They can have different appearances; some are short and wide, others are tall and slim, some are small, others are large. In this thesis a tank of 6 m in both diameter and height has been used to obtain numerical results of the stresses in the tank. READ MORE

6. 5. Eastern Tropical Pacific ITCZ and Lightning Activity

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Freja Söderberg; [2014]
   Keywords : Intertropical convergence zone; Lightning activity; Eastern tropical Pacific;

   Abstract : This study has been performed as a pilot study for a project regarding the meridional migration of the Intertropical Convergence Zone (ITCZ) and its relationship with lightning activity in the Eastern Tropical Pacific (ETP). Objectives of this study were to analyze and improve lightning data to be used for such a study and to decide on a method and proper time scale of data analysis and ITCZ index development for this study.
