    • Atmospheric response to removal of Southern Hemisphere sea ice - a model study 

      Ravnestad, Kristen Myklebust (Master thesis, 2010-06-01)
      The atmospheric response to the removal of Southern Hemisphere sea ice is studied using the ICTP AGCM (SPEEDY) model with an uncoupled ocean. The results show large increases in surface heat flux from the ocean to the ...
    • Atmospheric response to zonally averaged sea surface temperatures in the North Atlantic - a model study 

      Fagerli, Stig-Arild (Master thesis, 2008-05-29)
      A less dynamically active ocean will most likely lead to a more zonal sea surface temperature (SST) distribution. In order to identify if, and how such an effect affects the atmospheric variability, idealized experiments ...
