  1. 1. An investigation into ocean thermodynamics and water-mass transformation

    Författare :Magnus Hieronymus; Nycander Jonas; Stephen Griffies; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean thermodynamics; water-mass transformation; buoyancy; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : This thesis presents oceanic budgets of potential temperature, salinity and buoyancy as well as a novel way of diagnosing water-mass transformation in salinity-temperature space. The buoyancy of seawater is given by a nonlinear function of temperature, salinity and pressure and much of the work in this thesis revolves around how fluxes of heat and salinity influence the buoyancy of seawater through these nonlinearities.

  3. 2. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes

    Författare :Christian Nohr; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Water and Heat budgets; Deep-water mixing; Internal Wavedrag; Dynamical Sea Ice production; Sea Ice dynamics;

    Sammanfattning : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. LÄS MER

  4. 3. Freshwater processes and water mass transformation in the Arctic Ocean

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

    Sammanfattning : 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. LÄS MER

  5. 4. The interplay between atmosphere, hydrology and land use by environmental modelling

    Författare :Fabio Pereira; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land use changes; expansion of sugarcane; hydrological cycle; coupled models;

    Sammanfattning : Interactions between land surface and atmosphere induced by human activities and natural environmental dynamics act on a time scale that varies from seconds to millions of years. It is by exchanging heat, water, energy and carbon that land surface and atmospheric processes are closely interrelated and influence each other in reciprocal ways. LÄS MER

  7. 5. Water and heat exchange processes over the Baltic sea

    Författare :Anna Rutgersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Sammanfattning : Before we can reach understanding of the global climate and predict climate changes accurately we must be able to understand water and energy budgets. The atmosphere-water exchange processes are of great importance. LÄS MER
