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

   Sammanfattning : Airborne measurements performed within the framework of NOPEX (Northern Hemisphere Land Surface Climate Processes Experiment) have been used to study processes related to fluxes of momentum, heat, and moisture in the boundary layer in the Swedish boreal region. The NOPEX area is characterized as heterogeneous with respect to vegetation. LÄS MER

3. 2. Boundary Layer Parametrization in Numerical Weather Prediction Models

   Författare :Jacob Svensson; Gunilla Svensson; Michael Tjernström; Patrick Samuelsson; Stockholms universitet; []

   Sammanfattning : Numerical weather prediction (NWP) and climate models have shown to have a challenge to correctly simulate stable boundary layers and diurnal cycles. This aim of this study is to evaluate, describe and give suggestions for improvements of the descriptions of stable boundary layers in operational NWP models. Two papers are included. LÄS MER
