2. 16. Ridged sea ice modelling in climate applications

   Author : Sebastian Mårtensson; Markus Meier; Kristofer Döös; Peter A. Lundberg; Frank Kauker; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic ocean; Baltic Sea; sea ice; ice dynamics; numerical modelling; climate; ice deformation; ice compression; physical and biogeochemical interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. READ MORE

4. 17. Unraveling the thermohaline structure of the Southern Ocean using functional data analysis

   Author : Etienne Pauthenet; Fabien Roquet; Jonas Nycander; Alberto Naveira Garabato; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; Front; Water mass; Antarctic Polar Front; Descriptive Physical Oceanography; Functional Principal Component Analysis; Elephant Seal; Biologging; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : The Southern Ocean connects the Indian, Pacific and Atlantic Oceans and provides a direct pathway to exchange mass, heat and salt across the Global Ocean, therefore playing an important role in the global climate system. Due to the complexity of its structure and the general inadequacy of its sampling, both in time and space, it remains a challenge to describe and visualize the three dimensional pattern of its circulation and the associated tracer distribution (temperature, salinity, oxygen or nutrients).

5. 18. Freshwater processes and water mass transformation in the Arctic Ocean

   Author : Per Pemberton; Markus Meier; Johan Nilsson; Igor Polyakov; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : This thesis explores freshwater-related processes and water mass transformation in the Arctic Ocean. Knowledge of these processes is important from both a local and a global perspective. Globally, because the export of cold and low saline water and sea ice might influence the North Atlantic and global meridional overturning circulation. READ MORE

6. 19. Atmospheric dynamics and the hydrologic cycle in warm climates

   Author : Henrik Carlson; Rodrigo Caballero; Johan Nilsson; Jonathan L. Mitchell; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superrotation; early Eocene; warm climates; Madden-Julian Oscillation; the hydrologic cycle; vegetation sensitivity; large-scale circulation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Past warm climates represent one extreme of Earth's known climate states. Here, we study warm climates in both idealized simulations and full-complexity general circulation model (GCM) simulations of the early Eocene epoch, approximately 50 million years ago. READ MORE

7. 20. A large-eddy simulation perspective on Arctic airmass transformation and low-level cloud evolution

   Author : Antonios Dimitrelos; Annica Ekman; Caballero Rodrigo; Rune Grand Graversen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; mixed phase clouds; sea ice; Arctic amplification; atmospheric energy transport; CCN; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

   Abstract : The Arctic is currently warming faster than other regions of the Earth. Many processes and feedbacks contribute to the enhanced warming. Among these are the radiative effects of clouds. READ MORE
