1. 1. The exchange of sensible and latent heat over the sea

   Författare :Erik Sahlée; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary-layer; Air-sea interaction; turbulent fluxes; parameterization; Meteorology; Meteorologi;

   Sammanfattning : Analysis of the neutral exchange coefficients for latent and sensible heat, CEN and CHN, based on measurements from the Östergarnsholms site in the Baltic Sea has been made. The data set used for the CHN study was based on the very accurate MIUU-instrument. LÄS MER

3. 2. Språket och skolämnet svenska som andraspråk : Om elevers språk och skolans språksyn

   Författare :Anna Sahlée; Catharina Nyström Höög; Åke Viberg; Kjell Lars Berge; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Conception of language; text; Swedish as a second language; national test; policy for education; text analysis; student language; language as system; language as activity; systemic functional grammar; Nordiska språk; Scandinavian Languages;

   Sammanfattning : Since the school subject Swedish as a second language was established in the Swedish school system in the mid-1990s, the organization of the subject has varied widely across schools, and the outcomes have been poor. This thesis investigates these problems linguistically. LÄS MER

4. 3. Fluxes of Sensible and Latent Heat and Carbon Dioxide in the Marine Atmospheric Boundary Layer

   Författare :Erik Sahlée; Ann-Sofi Smedman; Anna Rutgersson; Sören Larsen; Uppsala universitet; []
   Nyckelord :Meteorology; Sensible heat flux; Latent heat flux; Carbon dioxide; Turbulent exchange; Global heat fluxes; Marine boundary layer; Air-sea interaction; Meteorologi;

   Sammanfattning : Oceans cover about 70% of the earth’s surface. They are the largest source of the atmospheric water vapour and act as enormous heat reservoirs. Thus in order to predict the future weather and climate it is of great importance to understand the processes governing the exchange of water vapour and heat between the ocean and atmosphere.

5. 4. Mechanisms controlling air-sea gas exchange in the Baltic Sea

   Författare :Lucía Gutiérrez-Loza; Anna Rutgersson; Erik Sahlée; Marcus Wallin; John Prytherch; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Air-sea gas exchange; Baltic Sea; CO2 flux; methane flux;

   Sammanfattning : Carbon plays a major role in physical and biogeochemical processes in the atmosphere, the biosphere, and the ocean. CO2 and CH4 are two of the most common carbon-containing compounds in the atmosphere, also recognized as major greenhouse gases. LÄS MER

7. 5. On mechanisms controlling air-sea gas exchange

   Författare :Lucía Gutiérrez-Loza; Anna Rutgersson; Erik Sahlée; Marcus B. Wallin; Tom Bell; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Air-sea gas exchange; eddy covariance; gas transfer velocity; Baltic Sea; Meteorologi; Meteorology;

   Sammanfattning : Carbon is essential to the Earth’s system functioning, playing a major role in physical and biogeochemical processes in the atmosphere, the terrestrial biosphere, and the oceans. The concentration of carbon-based greenhouse gases in the atmosphere, such as carbon dioxide (CO2) and methane (CH4), has been increasing since the industrial era. LÄS MER
