  1. 1. Implementation and Analysis of Air-Sea Exchange Processes in Atmosphere and Ocean Modelling

    Författare :Björn Carlsson; Anna Rutgersson; Ann-Sofi Smedman; Öyvind Saetra; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sensible heat flux; Latent heat flux; Momentum flux; Wind stress; Marine boundary layer; Air–Sea interaction; Swell; Climate model; Ocean model; Roughness parameter; Drag coefficient; Wave breaking; Meteorology; Meteorologi;

    Sammanfattning : To understand and to predict the weather and climate, numerical models are important tools and it is crucial that the controlling processes are described correctly. Since 70% of the global surface is covered with water the description how the ocean and atmosphere communicates has a considerable impact. LÄS MER

  2. 2. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

    Författare :Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

    Sammanfattning : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. LÄS MER

  3. 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.

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

    Författare :Erik Sahlée; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Turbulence Structure and Fluxes over Sea

    Författare :Erik Nilsson; Anna Rutgersson; Mark Kelly; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Boundary-layer; Air-sea interaction; turbulent fluxes; Meteorology; Meteorologi;

    Sammanfattning : Understanding the processes that control air-sea exchange of momentum, sensible heat and moisture (latent heat) is of great importance for atmospheric and oceanic modelling. In the atmosphere, for instance, cyclone intensity and track depends on these processes. LÄS MER
